D. Hatanaka, Hiroaki Takeshita, Motoki Kataoka +3 more·Oct 6, 2023
A coupled ring-waveguide structure is at the core of bosonic wave-based information processing systems, enabling advanced wave manipulations such as filtering, routing, and multiplexing. However, its miniaturization is challenging due to momentum con...
Phonon engineering of atomic-scale defects in superconducting quantum circuits
Mo Chen, John Clai Owens, Harald Putterman +2 more·Oct 5, 2023
Noise within solid-state systems at low temperatures can typically be traced back to material defects. In amorphous materials, these defects are broadly described by the tunneling two-level systems (TLSs) model. TLS have recently taken on further rel...
Problem-tailored Simulation of Energy Transport on Noisy Quantum Computers
I. Chen, Kl'ee Pollock, Yongxin Yao +2 more·Oct 5, 2023
The transport of conserved quantities like spin and charge is fundamental to characterizing the behavior of quantum many-body systems. Numerically simulating such dynamics is generically challenging, which motivates the consideration of quantum compu...

We apply the adaptive variational quantum imaginary time evolution (AVQITE) method to prepare ground states of one-dimensional spin $S=1$ models. We compare different spin-to-qubit encodings (standard binary, Gray, unary, and multiplet) with regard t...
Tunneling of fluxons via a Josephson resonant level
T. Vakhtel, P. Kurilovich, M. Pita-Vidal +3 more·Oct 4, 2023
Fluxons in a superconducting loop can be coherently coupled by quantum phase slips occurring at a weak link such as a Josephson junction. If Cooper pair tunneling at the junction occurs through a resonant level, $2\pi$ quantum phase slips are suppres...
Group-theoretic error mitigation enabled by classical shadows and symmetries
Andrew Zhao, A. Miyake·Oct 4, 2023
Estimating expectation values is a key subroutine in quantum algorithms. Near-term implementations face two major challenges: a limited number of samples required to learn a large collection of observables, and the accumulation of errors in devices w...
