Phase transition in magic with random quantum circuits
Pradeep Niroula, Christopher David White, Qingfeng Wang +5
Magic is a property of quantum states that enables universal fault-tolerant quantum computing using simple sets of gate operations. Understanding the mechanisms by which magic is c…
Thermal Multi-scale Entanglement Renormalization Ansatz for Variational Gibbs State Preparation
Troy J. Sewell, Christopher David White, Brian Swingle
Many simulation tasks require that one first prepare a system's Gibbs state. We present a family of quantum circuits for variational preparation of thermal Gibbs states on a quantu…
Open-system spin transport and operator weight dissipation in spin chains
Yongchan Yoo, Christopher David White, Brian Swingle
We use non-equilibrium steady states to study the effect of dissipation-assisted operator evolution (DAOE) on the scaling behavior of transport in one-dimensional spin chains. We c…
Mana and thermalization: probing the feasibility of near-Clifford Hamiltonian simulation
Troy J. Sewell, Christopher David White
Quantum hydrodynamics is the emergent classical dynamics governing transport of conserved quantities in generic strongly-interacting quantum systems. Recent matrix product operator…
Localization crossover and subdiffusive transport in a classical facilitated network model of a disordered, interacting quantum spin chain
Kai Klocke, Christopher David White, Michael Buchhold
We consider the random-field Heisenberg model, a paradigmatic model for many-body localization (MBL), and add a Markovian dephasing bath coupled to the Anderson orbitals of the mod…
Effective dissipation rate in a Liouvillian graph picture of high-temperature quantum hydrodynamics
Christopher David White
At high temperature, generic strongly interacting spin systems are expected to display hydrodynamics: local transport of conserved quantities, governed by classical partial differe…
