Qblox Secures $26 Million Series A to Scale Quantum Control Stack
Dutch quantum technology company Qblox has closed a $26 million Series A round led by Quantonation and Invest-NL, funding the expansion of its modular, scalable quantum control stack technology.
Qblox, a Dutch company developing quantum control stack technology, has closed a $26 million Series A funding round. The investment was led by Quantonation and the Invest-NL Deep Tech fund, with additional participation from QDNL participations and the European Innovation Council (EIC). This is the company's first external equity investment.
The control stack is the layer of hardware and software that sits between a quantum processor and the classical systems used to operate it. It translates instructions into the precise signals required to manipulate qubits and read their states. As quantum computers grow in size and complexity, the demands on the control stack grow accordingly. Qblox's approach is modular and scalable, designed to keep pace with that growth without requiring wholesale replacement of existing infrastructure.
Niels Bultink, co-founder and CEO of Qblox, described the significance of the raise in the context of the company's trajectory. "It has always been clear to us that quantum technology should be seen as a value chain where we work with dedication on one crucial layer of the stack, currently serving over one hundred customers. Almost uniquely in the industry, this has allowed us to grow the company exponentially fueled by revenue rather than investments. With our first equity investment, we secure our long-term growth, positioning Qblox as the enabler for industrial-scale quantum systems."
The company's control solutions already serve more than 100 customers globally, across a range of quantum computing platforms. That installed base is notable. Most quantum hardware companies operate at pilot scale; Qblox's commercial traction suggests the control stack market is maturing ahead of the broader industry.
Oliver Tonneau, Partner at Quantonation, commented on the investment. "We have closely followed Qblox's impressive journey over the past four years. Their expertise in control stack development, and their unique modular and scalable technology make them a standout player in the field. We look forward to seeing the impact of this investment on their continued progress."
The Series A will fund expanded R&D, product development, and team growth. Longer term, Qblox's technology is positioned as foundational infrastructure for industrial-scale quantum systems, the layer that makes it possible for quantum processors to be deployed reliably outside specialist research environments.
The funding also reflects continued investor confidence in the European quantum ecosystem. Quantonation, Invest-NL, QDNL, and the EIC are among the most active backers of quantum technology development on the continent, and their collective participation signals broad institutional support for Qblox's approach.
Identity infrastructure sits at the boundary of most enterprise security models. For IAM engineers and security architects, post-quantum migration of SAML assertions and OIDC tokens requires understanding where quantum vulnerability actually lives and what major identity providers support today.
The concern that post-quantum TLS will slow down HTTPS connections is widespread and, in most production environments, wrong. This analysis covers Cloudflare deployment data, Chrome GREASE findings, Apple PQ3 numbers, and the four variables that actually determine production impact.
Classical optical repeaters work by measuring the incoming signal and re-amplifying it. Measure, copy, transmit. This is precisely what quantum networks cannot do. The no-cloning theorem, proved by Wootters and Zurek in 1982, establishes that an unknown quantum state cannot be copied. Quantum repeaters solve this constraint through entanglement swapping — without ever measuring the quantum state being transmitted.

PKI is the trust architecture underlying TLS, code signing, SSH, and most of enterprise security. RSA and ECDSA sign every link in the chain. Shor’s algorithm breaks both. Here is what that means and what replaces it.
The quantum threat to VPN security is present-tense: adversaries are capturing encrypted sessions now. This article explains which layer of a VPN tunnel is vulnerable, how ML-KEM addresses it, and which providers have shipped production post-quantum implementations.
At most enterprise security conferences in 2026, quantum computing and artificial intelligence share a stage. This article maps where the capabilities diverge, where they converge, and what the difference means for security architecture decisions.
A practitioner holding a CISSP, a CISM, and a GIAC GSEC in 2026 has credentials that satisfy most employer qualification frameworks. Put that same practitioner in charge of their organisation’s post-quantum cryptography migration programme and they will find that none of those credentials tells them how to select between ML-KEM-768 and ML-KEM-1024.
Four NIST standards were finalised in August 2024. They do not tell you which one to deploy first, which protocol represents the fastest migration path in your environment, or whether hybrid schemes are a destination or a waypoint. This is the practical decision framework for security architects in 2026.
The honest answer is that neither body offers what a quantum security professional actually needs. That is not a criticism. It is a statement of timing: NIST finalised ML-KEM, ML-DSA, SLH-DSA, and FN-DSA as standards in August and October 2024. Certification curricula operate on multi-year review cycles. What follows is a role-by-role assessment of which body's credentials serve quantum security professionals best given where the curricula actually are today.
The two terms are not interchangeable, and treating them as if they were produces real planning errors. NIST's Cryptography Resource Center uses post-quantum cryptography to mean classical algorithms running on standard hardware that resist quantum attacks. Quantum cryptography most commonly refers to quantum key distribution, which requires dedicated quantum optical hardware. They are fundamentally different migration paths.
In 1994, Peter Shor published a mathematical proof: on a quantum computer of sufficient size, integer factorisation and the discrete logarithm problem collapse from computationally infeasible to afternoon job. RSA security rests on the first problem. Every form of elliptic curve cryptography rests on the second. Both fall to the same core technique.
A quantum computer breaks the key exchange step of end-to-end encryption, not the bulk message cipher. The risk profile varies by application design. Signal and Apple iMessage have already shipped post-quantum key exchange. PGP email has not.
What a quantum security engineer actually does, what the role pays in 2026 in the US and UK, what skills matter at interview, and where the career leads. For the cybersecurity professional considering a pivot and the hiring manager writing the job description.
The news cycle treats quantum computing as either an existential emergency arriving next year or a distant curiosity with no current relevance. Both framings are wrong. What follows is an evidence-based answer to a precise question: when will a quantum computer become capable of breaking the encryption that protects internet communications, and what does that timeline mean for decisions you need to make now?
If you run a small business and someone has told you that quantum computers will soon break your encryption, the natural question is: does this actually affect me, and what do I need to do about it? The honest answer is more nuanced than either "nothing to worry about" or "you need an immediate security overhaul." The threat is real. For most small businesses, the response is measured and manageable.
No single qualification solves the quantum security problem in 2026. The certification market has not caught up to NIST’s post-quantum standards. Here is how to build the right combination, and in what order.
Zero Trust Architecture removes implicit network trust. Post-quantum cryptography migration removes algorithm vulnerability to a future quantum adversary. A ZTA deployed without PQC migration has cryptographic guarantees that expire in the 2033 to 2035 window, simultaneously across every pillar.
Google's Willow chip and IBM's Nighthawk processor are genuine scientific milestones. Neither changes the 2033-2035 Q-Day central estimate. Understanding why requires a short tour of what these announcements actually showed — and what they did not.
Available quantum security training clusters at opposite extremes: PhD-depth theory with no migration connection, or awareness briefings that explain Q-Day without equipping anyone to act. A rigorous practitioner curriculum sits between those positions. This article defines what it must contain.
There is no single EU quantum security regulation. There is instead a cluster of four general cybersecurity instruments whose requirements for cryptographic controls happen to include quantum vulnerabilities within their scope. This article maps what NIS2, DORA, the EU AI Act, and the Cyber Resilience Act each require in relation to quantum security.
Google's Willow chip in December 2024 confirmed below-threshold quantum error correction in hardware for the first time. Understanding what it demonstrated, and what it did not, is essential context for any Q-Day planning conversation. This article explains why error correction is the gating factor for Q-Day and what the Willow result changes.
Underwriter questionnaires are beginning to incorporate quantum security posture into risk assessment. This article maps what a credible answer looks like, and how DORA's ICT risk management framework shapes what an insurer expects to see from EU financial entities.
Less than the briefings suggest, but more than the sceptics acknowledge. This article works through the hardware landscape as it stands in 2026, assesses what published results mean when read carefully, and separates the engineering milestones that matter from the noise.
NIST published FIPS 203, 204, and 205 in August 2024. DORA entered full enforcement in January 2025. The regulatory infrastructure exists. The CPD infrastructure does not yet match it. This article maps the frameworks that do exist, identifies where quantum security competency sits within each, and sets out what a complete quantum security CPD record looks like in 2026.
Every security professional has read the headlines about national quantum programmes. What most enterprise security teams have not done is translate those headlines into a specific threat model for their organisation. This article does that translation, using official sources only, and draws a clear line between what the intelligence community has confirmed and what requires labelling as a planning assumption.
The IBM Nighthawk and Google Willow announcements attracted more executive-level attention than any quantum hardware development in years. Both results are genuine progress. Neither changes the 2033–2035 Q-Day central estimate that security planners rely on. This article compares four architecturally distinct approaches and frames progress against the metric that actually matters: fault-tolerant logical qubits.
Security teams at financial institutions, critical infrastructure operators, and defence contractors typically carry memberships with ISC(2), ISACA, or BCS. Those associations do important work. They also cannot serve as specialist quantum security communities, and in 2026 that distinction has started to matter in ways that are operationally concrete rather than theoretical.
Quantum security training is a buyer's market in the worst sense: provider marketing has converged on the same vocabulary regardless of actual quality. This article is a quality framework you can apply to any programme — verifiable from a curriculum document, a sample session, or a direct conversation with the programme team.
The standard reassurance that older data is encrypted and therefore protected does not hold against a CRQC running Shor's algorithm. This article explains why 2018-era TLS archives carry a specific and growing risk reaching its credible lower bound in 2030, and what risk management options remain for organisations that cannot re-encrypt historical archives.
The quantum threat does not map uniformly onto cryptography. Shor's algorithm breaks asymmetric cryptography completely. Grover's algorithm weakens symmetric cryptography. Those two outcomes require different responses on different timescales. This article explains the distinction and what it means for migration planning.
Hardware announcements in quantum computing follow a reliable pattern: a large headline number, a spectacular benchmark, and a wave of coverage about what it means for encryption. The coverage rarely explains the one piece of information that would let a security professional make a sensible risk judgement: the difference between a physical qubit and a logical qubit.
Critical national infrastructure is a different post-quantum problem. The data lifetimes are longer, the patching cycles are slower, and the disruption potential of a future decryption event is not a data breach notification. It is a power cut.
Every time you sign a contract digitally, download a software update, or visit a website over HTTPS, a digital signature is working in the background. The mathematics underpinning those signatures has a problem: a future quantum computer will be able to break it. NIST published its transition timeline in November 2024, and the clock is now running.
If you are evaluating hybrid post-quantum TLS deployment for production infrastructure, this article provides the numbers: CPU cycles, key sizes, bandwidth overhead per TLS handshake, real-world latency data from Cloudflare and Chrome deployments at scale, and the QUIC-specific constraints practitioners routinely underestimate.
Government security programmes increasingly encounter QKD in briefings and vendor pitches, often without a clear picture of where it has been deployed, what problems emerged, and why two leading government cybersecurity agencies have explicitly declined to endorse it. This article provides that picture.
Most post-quantum migration guidance directs organisations to ML-DSA for all signature needs. For firmware signing pipelines, long-lived code signing infrastructure, and document archiving with 50-year retention requirements, however, defaulting to ML-DSA without evaluating the alternatives leaves a technically superior option on the table. XMSS and LMS produce smaller signatures than ML-DSA-87 and carry the most conservative security assumption available in any deployed signature scheme today.
Writing about quantum threats to blockchain almost always starts at Layer 1: Shor's algorithm breaks secp256k1, Bitcoin and Ethereum wallet keys are at risk, the community needs to migrate. What it omits is where most on-chain economic activity actually runs today. Arbitrum and Optimism together process more transactions per day than Ethereum mainnet. These Layer 2 rollup systems sit on top of the ECDSA vulnerability, and they introduce a different and more complex PQC migration surface than Layer 1 alone.
Post-quantum VPN migration is not a single task. Enterprise VPN infrastructure spans three distinct protocol families, each with a different standardisation path, different integration mechanism for ML-KEM, and different maturity level in enterprise vendor implementations.
The terminology around quantum security has drifted badly enough that practitioners working from plausible-sounding assumptions are making procurement decisions, technical designs, and board presentations based on claims that do not hold up. Nine misconceptions, each with a concrete consequence when acted upon.
Most organisations do not have a cryptography problem. They have a hardcoded cryptography problem. The distinction matters because the solution to the first is algorithm replacement, and the solution to the second is architecture redesign. Post-quantum migration forces both, but the architectural work is what takes years and what the PQC literature consistently underweights.
Before 2021, most cyber insurance questionnaires asked whether you had a firewall and an incident response plan. Then ransomware losses climbed steeply enough to move underwriters. The same mechanism exists for post-quantum cryptography. Loss events have not occurred yet, but the architecture of how quantum risk enters the insurance market is visible now.
When Apple launched iMessage PQ3 in February 2024, coverage declared that iPhones were now quantum-safe. When Google deployed hybrid post-quantum TLS through Chrome, similar statements followed. Both claims require qualification. Post-quantum on mobile is not a single thing. It describes at least four distinct cryptographic layers on a device, each with a different migration status.
Signal, iMessage, and WhatsApp all made post-quantum announcements between 2023 and 2024. Each application addressed a specific cryptographic component. None of them addressed everything. Understanding what changed, what remains classically vulnerable, and why the distinction matters requires looking at the actual protocol mechanics rather than the press releases.
