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

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 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 ...

Quantum communication has long promised unbreakable encryption, but the hardware has struggled to escape the lab. A new generation of laser-written glass chips is changing that equation, carving three ...

Researchers at the University of Science and Technology of China (USTC) demonstrated a quantum repeater module that addresses a key scalability bottleneck in fiber-based quantum networks.

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

The punishingly cold temperatures and fragile quantum states at the heart of a quantum computer put extreme constraints on the electronics that support them. So far, quantum computing companies have ...
