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 ...

A new theory suggests our universe and a time-reversed twin could emerge together. This quantum approach avoids singularities and offers an explanation for dark energy. Traditional cosmological models ...

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The ...
