Observation of Improved Accuracy over Classical Sparse Ground-State Solvers using a Quantum Computer
William Kirby, Bibek Pokharel, Javier Robledo Moreno +25
Demonstrating quantum advantage over classical algorithms for ground state energy problems is an outstanding open problem in quantum computation. We experimentally demonstrate that…
Efficient Quantum Gibbs Sampling with Local Circuits
Dominik Hahn, Ryan Sweke, Abhinav Deshpande +1
The problem of simulating the thermal behavior of quantum systems remains a central open challenge in quantum computing. Unlike well-established quantum algorithms for unitary dyna…
Bounds on Autonomous Quantum Error Correction
Oles Shtanko, Yu-Jie Liu, Simon Lieu +2
Autonomous quantum memories are a way to passively protect quantum information using engineered dissipation that creates an ``always-on'' decoder. We analyze Markovian autonomous d…
Uncovering Local Integrability in Quantum Many-Body Dynamics
Oles Shtanko, Derek S. Wang, Haimeng Zhang +4
Interacting many-body quantum systems and their dynamics, while fundamental to modern science and technology, are formidable to simulate and understand. However, by discovering the…
Maximizing free energy gain
Artemy Kolchinsky, Iman Marvian, Can Gokler +6
Maximizing the amount of work harvested from an environment is important for a wide variety of biological and technological processes, from energy-harvesting processes such as phot…
Realization of Two-dimensional Discrete Time Crystals with Anisotropic Heisenberg Coupling
Eric D. Switzer, Niall Robertson, Nathan Keenan +7
A discrete time crystal (DTC) is the paradigmatic example of a phase of matter that occurs exclusively in systems out of equilibrium. This phenomenon is characterized by the sponta…
