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…
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…
Local Sensing with the Multi-Level AC Stark Effect
Andre Schneider, Jochen Braumüller, Lingzhen Guo +5
Analyzing weak microwave signals in the GHz regime is a challenging task if the signal level is very low and the photon energy widely undefined. A superconducting qubit can detect…
