Observation of a prethermal discrete time crystal
Antonis Kyprianidis, Francisco Machado, William Morong +9
The conventional framework for defining and understanding phases of matter requires thermodynamic equilibrium. Extensions to non-equilibrium systems have led to surprising insights…
Programmable Quantum Simulations of Spin Systems with Trapped Ions
C. Monroe, W. C. Campbell, L. -M. Duan +10
Laser-cooled and trapped atomic ions form an ideal standard for the simulation of interacting quantum spin models. Effective spins are represented by appropriate internal energy le…
Quantum Approximate Optimization of the Long-Range Ising Model with a Trapped-Ion Quantum Simulator
G. Pagano, A. Bapat, P. Becker +13
Quantum computers and simulators may offer significant advantages over their classical counterparts, providing insights into quantum many-body systems and possibly improving perfor…
Cryogenic Trapped-Ion System for Large Scale Quantum Simulation
G. Pagano, P. W. Hess, H. B. Kaplan +9
We present a cryogenic ion trapping system designed for large scale quantum simulation of spin models. Our apparatus is based on a segmented-blade ion trap enclosed in a 4 K cryost…
Observation of a Many-Body Dynamical Phase Transition with a 53-Qubit Quantum Simulator
J. Zhang, G. Pagano, P. W. Hess +6
A quantum simulator is a restricted class of quantum computer that controls the interactions between quantum bits in a way that can be mapped to certain difficult quantum many-body…
Non-thermalization in trapped atomic ion spin chains
P. W. Hess, P. Becker, H. B. Kaplan +10
Linear arrays of trapped and laser cooled atomic ions are a versatile platform for studying emergent phenomena in strongly-interacting many-body systems. Effective spins are encode…
Observation of a Discrete Time Crystal
J. Zhang, P. W. Hess, A. Kyprianidis +9
Spontaneous symmetry breaking is a fundamental concept in many areas of physics, ranging from cosmology and particle physics to condensed matter. A prime example is the breaking of…
Observation of Prethermalization in Long-Range Interacting Spin Chains
B. Neyenhuis, J. Smith, A. C. Lee +6
Statistical mechanics can predict thermal equilibrium states for most classical systems, but for an isolated quantum system there is no general understanding on how equilibrium sta…
Many-body localization in a quantum simulator with programmable random disorder
Jacob Smith, Aaron Lee, Philip Richerme +6
When a system thermalizes it loses all local memory of its initial conditions. This is a general feature of open systems and is well described by equilibrium statistical mechanics.…
