Fast thermal state preparation beyond native interactions
Alexander van Lomwel, Paul M. Schindler, Modesto Orozco-Ruiz +3
While questions on quantum simulation of ground state physics are mostly focussed on the realization of effective interactions, most work on quantum simulation of thermal physics e…
Walsh-Floquet Theory of Periodic Kick Drives
James Walkling, Marin Bukov
Periodic kick drives are ubiquitous in digital quantum control, computation, and simulation, and are instrumental in studies of chaos and thermalization for their efficient represe…
Parametric instabilities in a 2D periodically-driven bosonic system: Beyond the weakly-interacting regime
T. Boulier, J. Maslek, M. Bukov +6
We experimentally investigate the effects of parametric instabilities on the short-time heating process of periodically-driven bosons in 2D optical lattices with a continuous trans…
Geometric Speed Limit of Accessible Many-Body State Preparation
Marin Bukov, Dries Sels, Anatoli Polkovnikov
We analyze state preparation within a restricted space of local control parameters between adiabatically connected states of control Hamiltonians. We formulate a conjecture that th…
Glassy Phase of Optimal Quantum Control
Alexandre G. R. Day, Marin Bukov, Phillip Weinberg +2
We study the problem of preparing a quantum many-body system from an initial to a target state by optimizing the fidelity over the family of bang-bang protocols. We present compell…
