Demonstration of a scalable all-solid-state refrigerator exploiting diffusion geometries and limiting interfacial conductances at temperatures below 1 kelvin
Robert M. Young, Zachary Stegen, John X. Przybysz +32
Solid-state refrigerators using Normal-metal/Insulator/Superconductor (NIS) junctions have previously demonstrated excellent electron cooling but limited ability to cool phonons. T…
Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
High-Energy Collision of Quarks and Mesons in the Schwinger Model: From Tensor Networks to Circuit QED
Ron Belyansky, Seth Whitsitt, Niklas Mueller +4
With the aim of studying nonperturbative out-of-equilibrium dynamics of high-energy particle collisions on quantum simulators, we investigate the scattering dynamics of lattice qua…
Ultrastrong light-matter interaction in a multimode photonic crystal
Andrei Vrajitoarea, Ron Belyansky, Rex Lundgren +3
Harnessing the interaction between light and matter at the quantum level has been a central theme in atomic physics and quantum optics, with applications from quantum computation t…
Decoding conformal field theories: from supervised to unsupervised learning
En-Jui Kuo, Alireza Seif, Rex Lundgren +2
We use machine learning to classify rational two-dimensional conformal field theories. We first use the energy spectra of these minimal models to train a supervised learning algori…
Universal scattering with general dispersion relations
Yidan Wang, Michael J. Gullans, Xuesen Na +2
Many synthetic quantum systems allow particles to have dispersion relations that are neither linear nor quadratic functions. Here, we explore single-particle scattering in general…
Realizing and Probing Baryonic Excitations in Rydberg Atom Arrays
Fangli Liu, Seth Whitsitt, Przemyslaw Bienias +2
We propose a realization of mesonic and baryonic quasiparticle excitations in Rydberg atom arrays with programmable interactions. Recent experiments have shown that such systems po…
Observation of Domain Wall Confinement and Dynamics in a Quantum Simulator
W. L. Tan, P. Becker, F. Liu +11
Confinement is a ubiquitous mechanism in nature, whereby particles feel an attractive force that increases without bound as they separate. A prominent example is color confinement…
Real-time dynamics of string breaking in quantum spin chains
Roberto Verdel, Fangli Liu, Seth Whitsitt +2
String breaking is a central dynamical process in theories featuring confinement, where a string connecting two charges decays at the expense of the creation of new particle-antipa…
Torus Spectroscopy of the Gross-Neveu-Yukawa Quantum Field Theory: Free Dirac versus Chiral Ising Fixed Point
Michael Schuler, Stephan Hesselmann, Seth Whitsitt +3
We establish the universal torus low-energy spectra at the free Dirac fixed point and at the strongly coupled chiral Ising fixed point and their subtle crossover behaviour in the G…
Circuit Complexity across a Topological Phase Transition
Fangli Liu, Seth Whitsitt, Jonathan B. Curtis +5
We use Nielsen's geometric approach to quantify the circuit complexity in a one-dimensional Kitaev chain across a topological phase transition. We find that the circuit complexitie…
