We explore the boundary time-crystal transition at the level of quantum trajectories which result from continuous monitoring. This Letter is motivated by recent experiments [G. Ferioli, A. Glicenstein, I. Ferrier-Barbut, and A. Browaeys, Nat. Phys. 19, 1345 (2023)] realizing this many-...

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...

Even normal crystals, which you can observe in salt formations or snowflakes, defy the laws of physics: atoms shouldn’t “prefer” one point in space over another. But time crystals take it a step further: their atoms don’t just prefer being in different points in space, they do so at...
intriguing type of quantum system known as a discrete time crystal (DTC). Whereas normal, material crystals display a fixed-dimensional periodicity in their structure, DTCs repeat their properties in time, with cycles that have an integer multiple of the period of the force that causes the ...
Google May Have Created an Unruly New State of Matter: Time Crystals Presented by Presented byScience Pop Mech Pro: Science Google May Have Created an Unruly New State of Matter: Time Crystals Time crystals really don't like to play by the rules. That could be a good thing for quantum co...
Universal quantum computers are potentially an ideal setting for simulating many-body quantum dynamics that is out of reach for classical digital computers. We use state-of-the-art IBM quantum computers to study paradigmatic examples of condensed matter
Time crystals enter the real world of condensed matter Peter Hannaford, a physicist at Swinburne University of Technology in Melbourne, Australia, who was not involved in the research, describes the result as being important for the field of time crystals, as the QuTech-led team unambiguously demo...
CRYSTALS-DILITHIUM, Falcon, and SPHINCS+ are the new digital signature systems. “ Reviewers noted the high efficiency of the first two, and NIST recommends CRYSTALS-Dilithium as the primary algorithm, with FALCON for applications that need smaller signatures than Dilithium can provide. The third,...
