-state Potts ice
Mark Potts, S. A. Parameswaran, Roderich Moessner
Classical and quantum spin ice arguably provide the simplest route towards spin liquids and their emergent gauge fields. state Potts ice models have been constructed that gener…
Rigorous error bounds for dissipative thermal state preparation from weak system-bath coupling
Christopher Ong, S. A. Parameswaran, Benedikt Placke +1
Thermal state preparation is a central challenge in the simulation of quantum many-body systems. Yet, provably efficient algorithms for this task were only introduced recently [Che…
Towards Efficient Quantum Thermal State Preparation via Local Driving: Lindbladian Simulation with Provable Guarantees
Dominik Hahn, S. A. Parameswaran, Benedikt Placke
Preparing the thermal density matrix corresponding to a given Hamiltonian is a task of central interest across quantum many-body physics, and is partic…
Solvable Quantum Circuits in Tree+1 Dimensions
Oliver Breach, Benedikt Placke, Pieter W. Claeys +1
We devise tractable models of unitary quantum many-body dynamics on tree graphs, as a first step towards a deeper understanding of dynamics in non-Euclidean spaces. To this end, we…
Slow measurement-only dynamics of entanglement in Pauli subsystem codes
Benedikt Placke, S. A. Parameswaran
We study the non-unitary dynamics of a class of quantum circuits based on stochastically measuring check operators of subsystem quantum error-correcting codes, such as the Bacon-Sh…
