Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure communication at scale, and to connect ...

When we look up at the night sky, we take for granted the 'space' that stretches out infinitely and the 'time' that flows ...

In a pioneering twist on quantum networking, physicists have proposed using entangled atomic clocks to probe how gravity’s bending of space-time affects the quantum world. The work—led by researchers ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...

Quantum entanglement has baffled physicists since Einstein, Podolsky, and Rosen first questioned whether the quantum ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

A proposed experiment could shed light on the unknown interplay of quantum theory and general relativity. Quantum theory in curved spacetime can be theoretically understood beyond the limit at which ...

IBM Research's Spacetime PEC protocol combines two error-handling techniques to slash quantum sampling overhead by up to 63x, validated on a 27-qubit processor.

The preparation of quantum states with long-range correlations and topological entanglement is a key objective for quantum simulators and processors. A common approach is the Sequential Quantum ...

A deep-underground experiment in Italy has challenged a decades-old theory that gravity may destroy quantum superpositions. After 62 days of measurements at Gran Sasso, researchers found no trace of ...
