Securing a wireless link with MDI-QKD

Relying in part on techniques used to sharpen up images from ground-based telescopes, researchers in China have implemented a type of secure quantum communications protocol—known as measurement-device-independent quantum key distribution (MDI-QKD)—across a wireless link connecting […]

Quantum teleportation with 90% accuracy over 44 km

Researchers at California Institute of Technology have achieved conditional quantum teleportation of time-bin qubits at the telecommunication wavelength of 1536.5 nm. They measured teleportation fidelities of ≥ 90% that are consistent with an analytical model […]

Experimental Bell Tests with Reinforcement Learning

Terra Quantum, a Swiss startup, and University of Basel have developed a combination of reinforcement learning and simulated annealing for setting up efficient Bell tests useful for quantum cryptography.  Finding optical setups producing measurement results […]

Kudelski new focus on Quantum Security

Kudelski Security, the cybersecurity division within the Swiss Kudelski Group, announced today the launch of a new focus on Quantum Security, including expanded research and advisory services that enable security leaders and product and system […]

IBM Cloud delivers Quantum-Safe Cryptography

IBM today announced a series of cloud services and technologies designed to help clients maintain the highest available level of cryptographic key encryption protection to help protect existing data in the Cloud and prepare for future threats that […]

Hybrid quantum-classical scheme for prime factorization

Researchers have reported a quantum-classical hybrid scheme for factorization of bi-prime numbers (which are odd and square-free) using IBM’s quantum processors. The hybrid scheme has involved both classical optimization techniques and adiabatic quantum optimization techniques, […]
