Time crystals really don't like to play by the rules. That could be a good thing for quantum computing.
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-...
Qubit layout on ibmq_manhattan and ibmq_brooklyn chips with its 65 qubits (for the former, whole-device entanglement was demonstrated recently).The 57 black qubits are used for the simulations of discrete time crystals. Credit:Science Advances(2022). DOI: 10.1126/sciadv.abm7652 When you hear ...
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 ...
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
In the future it may even be possible to look at time itself, including the possibility of constructing the boundary between time going forward and back, as theory suggests. "It is an entire universe of study," Volovik says. The scientists observed the time quasicrystal and its transition to...
The spontaneous breaking of time translation symmetry has led to the discovery of a new phase of matter - the discrete time crystal. Discrete time crystals exhibit rigid subharmonic oscillations, which result from a combination of many-body interactions, collective synchronization, and ergodicity breakin...
Time Crystals in Quantum Computing 来自 Semantic Scholar 喜欢 0 阅读量: 3 作者: G Rajna 摘要: The breakthrough was made in the lab of Andrea Alù, director of the ASRC's Photonics Initiative. Alù and his colleagues from The City College of New York, University of Texas at Austin and ...
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...
The quantum internet1,2—in synergy with the internet that we use today—promises an enabling platform for next-generation information processing, including exponentially speed-up distributed computation, secure communication, and high-precision metrology. For fiber-based quantum networks, the distance ove...
