Kaiserslautern, Germany -- April 4, 2025 - In an era where data security is paramount, the advent of quantum computing poses significant threats to traditional encryption methods. Continuous-Variable ...

Continuous-variable quantum key distribution (CV-QKD) utilises the continuous degrees of freedom of light—typically the amplitude and phase quadratures of coherent states—to establish ...

Researchers at DTU have successfully distributed a quantum-secure key using a method called continuous variable quantum key distribution (CV QKD). The researchers have managed to make the method work ...

Figure 1: Schematic of a quantum key distribution system. The transmitter (Alice) and receiver (Bob) generate composable keys by transmitting quantum states over an insecure quantum channel, ...

Successful new field tests of a continuous-variable quantum key distribution (CV-QKD) system over commercial fiber networks could pave the way to its use in metropolitan areas. That is the key ...

Quantum Key Distribution (QKD) utilizes the laws of quantum physics to securely distribute keys to communication partners. Until now, however, QKD has required relatively large dedicated 19-inch ...

Scientists in China have reported quantum key distribution (QKD) on a 50 kilometer-long commercial fiber network. The team, from Peking University and Beijing University of Posts and ...

Researchers have taken a big step towards securing information against hacking. They have succeeded in using quantum encryption to securely transfer information 100 kilometers via fiber optic cable -- ...

Researchers at DTU have succeeded in using quantum encryption to securely transfer information 100 kilometres via fibre optic cable - roughly equivalent to the distance between Oxford and London.
