Quantum information processing relies on the precise control of non-classical states in the presence of many uncontrolled environmental degrees of freedom. The interactions between the relevant degrees of freedom and the environment are often viewed as detrimental, as they dissipate energy and decohere ...
A circuit board made from time crystals would involve thousands of atoms almost as cold as absolute zero, one of the conditions required for quantum phenomena to unfold. Krzysztof Sacha at the Jagiellonian University in Poland and his colleagues developed a mathematical blueprint for such “temporal...

As a rare example of a system in which Bose–Einstein condensation and superfluidity are reported at room temperature, polariton lasers are interesting for fundamental research and offer potential for applications in classical and quantum information technologies. In the past 10 years, new material ...
Keywords: quantum walks; spatial-multiplexing; time-multiplexing; spatial light modulators 1. Introduction The quantum walk is one of the most striking manifestations of how quantum interference leads to a strong departure between quantum and classical phenomena [1]. In its discrete version, namely, ...

Before long, astute observers spotted distinct similarities between discrete time crystals in quantum systems and so-called parametric resonators, a concept in classical physics reaching back to work by Michael Faraday in 1831. The connection between these two bodies of work remained, however, opaque....
144 While not mature enough to solve “real-world” problems for at least another decade, they held promise for an exponential speed-up to some scientific and engineering systems. Researchers still need to home in on whether turbulence is such a problem that is hard for a classical computer ...
