An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

Researchers from the Austrian Academy of Sciences and the University of Vienna have demonstrated a precise method for reversing time in a quantum system, achieving an average fidelity of more than 95% ...

Add Yahoo as a preferred source to see more of our stories on Google. For years, physicists have been trying to design clocks that can measure tiny durations of time with extreme precision. Quantum ...

Many systems obey simple, linear rules: If you pull twice as hard on a spring, it stretches twice as far. However, when we introduce very large forces or complicated interactions, that linear rule ...
