But could one of physics’s most mind-bending states of matter become a workhorse for quantum technology? For the first time, researchers have successfully coupled a continuous time crystal-a quantum ...

At each sampling time instant, one observes system output and action to form discrete-time rewards. The sampled input-output data are collected along the trajectory of the dynamical system in ...

Sigma-delta converters are in wide use among applications that demand high precision and accuracy. A variant of the sigma-delta architecture, called the continuous-time sigma delta (CT-S?), has found ...
