Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

The operation and performance of quantum computers relies on the ability to realize and control entanglement between multiple qubits. Yet entanglement between many qubits is inherently susceptible to ...

A new study takes the GHZ paradox, which describes how quantum theory can't be described by local realistic descriptions, to ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

You are watching a long-standing assumption in physics and engineering quietly fall apart. Researchers at Northwestern ...

Bruce Yabsley works for the School of Physics at the University of Sydney, and receives funding from the Australian Research Council. He is a member of the ATLAS Collaboration at CERN, in Geneva, ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew. When you purchase through links on our site, we may earn an ...

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 ...

Scientists have for the first time observed quantum entanglement — a state in which particles intermingle, losing their individuality so they can no longer be described separately — between quarks.
