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 particula…
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…
