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…
Engineering Large Stark Shifts for Control of Individual Clock State Qubits
Aaron C. Lee, Jacob Smith, Philip Richerme +4
In quantum information science, the external control of qubits must be balanced with the extreme isolation of the qubits from the environment. Atomic qubit systems typically mitiga…
Experimental Realization of a Quantum Integer-Spin Chain with Controllable Interactions
C. Senko, P. Richerme, J. Smith +4
The physics of interacting integer-spin chains has been a topic of intense theoretical interest, particularly in the context of symmetry-protected topological phases. However, ther…
Coherent Imaging Spectroscopy of a Quantum Many-Body Spin System
C. Senko, J. Smith, P. Richerme +3
Quantum simulators, in which well controlled quantum systems are used to reproduce the dynamics of less understood ones, have the potential to explore physics that is inaccessible…
Beat note stabilization of mode-locked lasers for quantum information processing
R. Islam, W. C. Campbell, T. Choi +18
We stabilize a chosen radiofrequency beat note between two optical fields derived from the same mode-locked laser pulse train, in order to coherently manipulate quantum information…
Experimental Performance of a Quantum Simulator: Optimizing Adiabatic Evolution and Identifying Many-Body Ground States
Philip Richerme, Crystal Senko, Jacob Smith +3
We use local adiabatic evolution to experimentally create and determine the ground state spin ordering of a fully-connected Ising model with up to 14 spins. Local adiabatic evoluti…
Emergence and Frustration of Magnetic Order with Variable-Range Interactions in a Trapped Ion Quantum Simulator
R. Islam, C. Senko, W. C. Campbell +7
Frustration, or the competition between interacting components of a network, is often responsible for the complexity of many body systems, from social and neural networks to protei…
