“Quantum Safe Networks: Threats, Best Practices and Use Cases”

The range of quantum technologies is quite broad, encompassing far more than just quantum computing. Nokia is putting quantum mechanics to use as a tool for communication, privacy and detection, as well as computation. Nokia categorizes quantum technologies into four distinct areas: Quantum computing harnesses the quantum states of individual particles, called qubits, to perform complex calculations no classical computer could ever match. Our researchers are investigating topological and photonic approaches to quantum computing, as well as researching new quantum algorithms. Quantum networks carry quantum information. We are researching how these networks can create a quantum internet connecting quantum computers and sensors, as well as how quantum mechanics can unlock new possibilities in communication. Quantum security technologies will safeguard data and communications from the inevitable threat of quantum computers being used for malicious purposes. Nokia security experts are developing a new generation of encryption to prevent future quantum attacks, as well as researching communications technology that will lock information behind the immutable laws of physics. Quantum sensing will detect natural phenomena that we have never been able to measure before. We are researching both quantum photonic sensors and quantum magnetic-field sensors, which have several potential applications in optical and wireless communications, positioning services, and medicine.
