Entanglement is a property in quantum mechanics that seemed so unbelievable and so lacking in detail that, 66 years ago this spring, Einstein called it "spooky action at a distance." But a mathematician at Case Western Reserve ...

In a game of one-upmanship, a Chinese team of physicists has figured out how to entangle eight photons simultaneously and to observe them in action; the previous record was six. In a paper published in arXiv, the team from ...
Quantum physics has a reputation for being mysterious and mathematically challenging. That makes it all the more surprising that a new technique to detect quantum behaviour relies on a familiar tool: a "zip" program you might ...

(Phys.org)—Two Chinese teams working with quantum encryption and entanglement have achieved two more goals toward building a quantum space-based communication network. In the first experiment, one team succeeded in sending ...
Every Friday afternoon for several years in the 1970s, a group of underemployed quantum physicists met at Lawrence Berkeley Laboratory, in Northern California, to talk about a subject so peculiar it was rarely discussed in ...
