Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

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 ...

In 2024, a quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber ...

Keeping perfect time is far trickier than it sounds. The world’s best clocks that ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist ...

Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a separate line of theoretical work suggesting that time crystals, exotic quantum ...

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

Quantum computing technology is complex, getting off the ground and maturing. There is promise of things to come. potentially changing the computing paradigm.

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

A breakthrough optical design allows quantum computers to read information in parallel, a key step toward building ...
