Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, ...

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending ...

To push beyond this boundary, the team developed a quantum repeater system capable of creating memory–memory entanglement between two separate nodes. By linking these nodes through entanglement ...

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is that a malicious third party could steal the key by hacking the devices the ...

Company sends quantum-encrypted data through 1,032-kilometer fiber-optic network at more than 10,000 times previous speed record. As a result, Terra Quantum sets world records in both data ...

Quantum key distribution promises ultra-secure communication by using the strange rules of quantum physics to detect eavesdroppers instantly. But even the most secure quantum link can falter if the ...

Korean researchers have successfully established the world’s first “Measurement Protection (MP)” theory that enables stable Quantum Key Distribution (QKD) without need for measurement correction of ...

Beijing University. Chinese scientists have built the world's first large-scale quantum key distribution (QKD) network based on integrated ...

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated ...
