Accuracy and Resource Estimations for Quantum Chemistry on a Near-term Quantum Computer
Michael Kühn, Sebastian Zanker, Peter Deglmann +2
The study and prediction of chemical reactivity is one of the most important application areas of molecular quantum chemistry. Large-scale, fully error-tolerant quantum computers c…
Finding the ground state of the Hubbard model by variational methods on a quantum computer with gate errors
Jan-Michael Reiner, Frank Wilhelm-Mauch, Gerd Schön +1
A key goal of digital quantum computing is the simulation of fermionic systems such as molecules or the Hubbard model. Unfortunately, for present and near-future quantum computers…
Probing the Tavis-Cummings level splitting with intermediate-scale superconducting circuits
Ping Yang, Jan David Brehm, Juha Leppäkangas +7
We demonstrate the local control of up to eight two-level systems interacting strongly with a microwave cavity. Following calibration, the frequency of each individual two-level sy…
Gap-independent cooling and hybrid quantum-classical annealing
L. S. Theis, Peter K. Schuhmacher, M. Marthaler +1
In this letter we present an efficient gap-independent cooling scheme for a quantum annealer that benefits from finite temperatures. We choose a system based on superconducting flu…
Resonance inversion in a superconducting cavity coupled to artificial atoms and a microwave background
Juha Leppäkangas, Jan David Brehm, Ping Yang +4
We demonstrate how heating of an environment can invert the line shape of a driven cavity. We consider a superconducting coplanar cavity coupled to multiple artificial atoms. The m…
Effects of gate errors in digital quantum simulations of fermionic systems
Jan-Michael Reiner, Sebastian Zanker, Iris Schwenk +4
Digital quantum simulations offer exciting perspectives for the study of fermionic systems such as molecules or lattice models. However, with quantum error correction still being o…
