Theoretical physicists in the US have discovered a "speed limit" on the time taken for quantum information to spread through ...

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser ...

"Time measurement always has to do with entropy," explains Marcus Huber. In every closed physical system, entropy increases and it becomes more and more disordered. It is precisely this development ...
