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. Ferrie
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...

Time crystals really don't like to play by the rules. That could be a good thing for quantum computing.
between distant qubits suffers from spurious interactions and disorder. Here, the authors report up to an order of magnitude enhancement in the quality factor of a swap operation of eigenstates in a quantum dot chain, by using a periodic driving protocol inspired by discrete time crystals. ...
Over four years ago, other collaborators and Iuncovered a thermodynamics problem, as did two other groups at the same time. Thermodynamicists often consider small systems that interact with large environments, like a magnolia flower releasing its perfume into the air. The two systems—magnolia flowe...
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 ...
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...
particles such aselectronsand photons that are given either a charge or polarization to act as a 0, 1 or any of the possible states in between. The ability of these units, calledqubits, to be in more than one state at a time is what gives quantum computers much of their processing ...
Two sets of physicists, one group based at Harvard and the other at the University of Maryland, have reported the discovery of time crystals, a state of matter whose existence seems to trash the notion of cause-and-effect. The Harvard group describes time crystals this way: They are substanc...
