Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings show that a quantum process can appear memoryless from one perspective while ...

Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has ...

Time feels like the most basic feature of reality. Seconds tick, days pass, and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
