Boundary-driven quantum systems near the Zeno limit: steady states and long-time behavior
Eric A. Carlen, David A. Huse, Joel L. Lebowitz
We study composite open quantum systems with a finite-dimensional state space governed by a Lindblad equation wh…
Crystalline Spectral Form Factors
Dmitrii A. Trunin, David A. Huse
We investigate crystalline-like behavior of the spectral form factor in unitary quantum systems with extremely strong eigenvalue repulsion. Using a low-temperature Coulomb gas as a…
Roughening Transition in Quantum Circuits
Hyunsoo Ha, David A. Huse, Grace M. Sommers
We explore a roughening phase transition that occurs in the entanglement dynamics of certain quantum circuits. Viewing entanglement as the free energy of a membrane in a circuit-de…
Observation of a Fault Tolerance Threshold with Concatenated Codes
Grace M. Sommers, Michael Foss-Feig, David Hayes +2
We introduce a fault-tolerant protocol for code concatenation of a generalized Shor code using a butterfly network architecture with high noise thresholds and low ancilla overhead…
Stationary states of boundary driven quantum systems: some exact results
Eric A. Carlen, David a. Huse, Joel L. Lebowitz
We study finite-dimensional open quantum systems whose density matrix evolves via a Lindbladian, . Here is the Hamiltonian of the isolated system a…
Dynamically generated concatenated codes and their phase diagrams
Grace M. Sommers, David A. Huse, Michael J. Gullans
We formulate code concatenation as the action of a unitary quantum circuit on an expanding tree geometry and find that for certain classes of gates, applied identically at each nod…
Molecular Entanglement Witness by Absorption Spectroscopy in Cavity QED
Weijun Wu, Francesca Fassioli, David A. Huse +1
Producing and maintaining molecular entanglement at room temperature and detecting multipartite entanglement features of macroscopic molecular systems remain key challenges for und…
Quantum coarsening and collective dynamics on a programmable simulator
Tom Manovitz, Sophie H. Li, Sepehr Ebadi +15
Understanding the collective quantum dynamics of nonequilibrium many-body systems is an outstanding challenge in quantum science. In particular, dynamics driven by quantum fluctuat…
Quantum and classical coarsening and their interplay with the Kibble-Zurek mechanism
Rhine Samajdar, David A. Huse
Understanding the out-of-equilibrium dynamics of a closed quantum system driven across a quantum phase transition is an important problem with widespread implications for quantum s…
Macroscopic and Microscopic Thermal Equilibrium
Sheldon Goldstein, David A. Huse, Joel L. Lebowitz +1
We study the nature of and approach to thermal equilibrium in isolated quantum systems. An individual isolated macroscopic quantum system in a pure or mixed state is regarded as be…
