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 ...

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 ...

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

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to work on innovative new ways to encrypt information. One such method is ...

Quantum key distribution (QKD) exploits the intrinsic properties of quantum mechanics to enable the secure exchange of cryptographic keys between distant parties. By utilising quantum states of light, ...

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 ...

Quantum secure communication uses quantum mechanisms to secure classical (non-quantum) communication and is fundamental to national information security and socioeconomic development. One of the ...
