Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, ...

An experiment with a toy universe made up of extremely cold atoms shows how time can emerge from quantum interactions, instead of existing by default ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study suggests trapped-ion atomic clocks could detect quantum superpositions of time, opening a path toward uniting quantum ...

The Laboratory team’s quantum “demon” uses information about a quantum system’s state and measurement results to drive similarly unusual processes, reversing the usual arrow of time in a quantum ...

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, ...
