The discovery of quantum mechanics opened the door to fundamentally new ways of communicating, processing, and protecting data. With a quantum revolution well underway, long unimaginable opportunities ...

For decades, entanglement has been the hallmark of quantum weirdness, a ghostly connection between particles that Einstein famously called "spooky action at a distance." It is at the heart of quantum ...

For years, scientists have imagined a future where secure quantum links circle the planet from space. Satellites would create pairs of entangled photons and send them down to distant stations on Earth ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Jim Baggott is a science writer based in Cape Town, South Africa. He is co-author with John Heilbron of Quantum Drama. Quantum mechanics is an extraordinarily successful scientific theory, on which ...

Researchers developed a chip-scale platform that efficiently generates entangled photons, advancing scalable quantum tech for computing, cryptography, and sensing. (Nanowerk News) Entangled photons ...

Physicists have provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, can be inextricably linked, in ...
