An external drive can improve the coherence of a quantum many-body system by averaging out noise sources. It also be used to realize models that are inaccessible in static limit, through Floquet Hamiltonian engineering. The full possibilities for combining these tools remain unexplored. We develop requirements needed pulse sequence decouple from an field without altering intended dynamics. Demonstrating this technique experimentally ion-trap platform, we show it provide large improvement...
Prethermal time crystal Characterizing and understanding different phases of matter in equilibrium is usually associated with the process thermalization, where system equilibrates. Recent efforts probing nonequilibrium systems have revealed that periodic driving can suppress natural tendency for equilibration yet still form new, phases. Kyprianidis et al. used a quantum simulator composed 25 trapped ion qubits spins to observe such phase matter: disorder-free prethermal discrete crystal. The...
Humans operating in dynamic environments with limited visibility are susceptible to collisions moving objects, occupational hazards, and/or other agents, which can result personal injuries or fatalities. Most existing research has focused on using vibrotactile cues address this challenge. In work, we propose a fundamentally new approach that utilizes variable impedance an active exoskeleton guide humans away from hazards and towards safe areas. This framework combines artificial potential...
Quantum networking protocols relying on interference and precise time-of-flight measurements require high-precision clock synchronization. This study describes the design, implementation, characterization of two optical time transfer methods in a metropolitan-scale quantum research testbed. With active electronic stabilization, sub-picosecond deviation (TDEV) was achieved at integration times between 1 105 s over 53 km deployed fiber. Over same periods, 10-ps level TDEV observed using White...
<title>Abstract</title> The spontaneous formation of particle pairs is one the most intriguing phenomena in nature. A canonical example when potential energy between two elementary particles increases with their separation, as if were confined to another by a tense string. When separation exceeds critical value, new can form, which causes string break. String-breaking dynamics quantum chromodynamics, theory strong force, play fundamental role high-energy collisions and evolution matter early...
Abstract Universality and scaling laws are hallmarks of equilibrium phase transitions critical phenomena 1-3 . However, extending these concepts to non-equilibrium systems is an outstanding challenge. Despite recent progress in the study dynamical phases 4,5 , universality classes for far less understood than those 6 In this work, using a trapped-ion quantum simulator with single-ion resolution, we investigate nature fluctuations following quench point. We probe spin after series quenches...
