High-dimensional quantum key distribution (QKD) and entanglement harness quantum systems with more than two levels—qudits—to enhance information capacity, security and resilience against noise. By ...

The type of system employing continuous variables, such as light field quadrature for signal modulation, is an important branch for quantum key distribution. Achieving a high key rate using quantum ...

A new type of hologram technology has been developed that uses the motion of light as a key, revealing information only under specific conditions. This is gaining attention as a novel approach that ...

If you’ve managed secure cryptographic infrastructure, you know the challenges of physical secure rooms, from the high cost of SCIF-standard facilities to the operational burdens of multi-operator ...

Most people assume that turning on two-factor authentication is enough to protect their accounts. It’s a big improvement. But it’s not enough. If someone can take control of your phone number, trick ...
