Continuous Hamiltonian dynamics on digital quantum computers without discretization error
Etienne Granet, Henrik Dreyer
We introduce an algorithm to compute Hamiltonian dynamics on digital quantum computers that requires only a finite circuit depth to reach an arbitrary precision, i.e. achieves zero…
Robust Extraction of Thermal Observables from State Sampling and Real-Time Dynamics on Quantum Computers
Khaldoon Ghanem, Alexander Schuckert, Henrik Dreyer
Simulating properties of quantum materials is one of the most promising applications of quantum computation, both near- and long-term. While real-time dynamics can be straightforwa…
Non-Abelian Topological Order and Anyons on a Trapped-Ion Processor
Mohsin Iqbal, Nathanan Tantivasadakarn, Ruben Verresen +15
Non-Abelian topological order (TO) is a coveted state of matter with remarkable properties, including quasiparticles that can remember the sequence in which they are exchanged. The…
Experimental demonstration of the advantage of adaptive quantum circuits
Michael Foss-Feig, Arkin Tikku, Tsung-Cheng Lu +16
Adaptive quantum circuits employ unitary gates assisted by mid-circuit measurement, classical computation on the measurement outcome, and the conditional application of future unit…
Topological Order from Measurements and Feed-Forward on a Trapped Ion Quantum Computer
Mohsin Iqbal, Nathanan Tantivasadakarn, Thomas M. Gatterman +13
Quantum systems evolve in time in one of two ways: through the Schrödinger equation or wavefunction collapse. So far, deterministic control of quantum many-body systems in the lab…
Volume-law to area-law entanglement transition in a non-unitary periodic Gaussian circuit
Etienne Granet, Carolyn Zhang, Henrik Dreyer
We consider Gaussian quantum circuits that alternate unitary gates and post-selected weak measurements, with spatial translation symmetry and time periodicity. We show analytically…
