Open system probes of renormalization group flow
Andrew Keefe, Brenden Bowen, Saptarshi Biswas +3
Open system probes can provide an efficient means to characterize quantum many-body systems by employing them as engineered environments. The key idea is to map long-range spatial…
High-fidelity iSWAP gate with Double Transmon Coupler
Tarush Tiwari, Sudhir K. Sahu, Guilhem Ribeill +6
Entangling operations are at the heart of all approaches to quantum information processing. Parametric gates, in particular, offer a versatile solution to strongly couple off-reson…
Practical Limits to Single-Mode Vacuum Squeezing with a SNAIL Parametric Amplifier
Theodore Shaw, Debsuvra Mukhopadhyay, Zhuoqun Hao +4
We characterize single-mode vacuum squeezing generated by a SNAIL Parametric Amplifier (SPA) operated under conditions representative of practical sensing and qubit-readout experim…
Long-range waveguide-quantum electrodynamics with left-handed transmission lines
P. Goswami, J. Liu, C. A. González-Gutiérrez +1
While engineering long-range light-matter interactions is the principal aim in waveguide-QED, ironically most of the building blocks rest on local short-range couplings, such as ne…
Hybrid superinductance with Al/InAs
Junseok Oh, Ido Levy, Tyler Cowan +4
We report microwave spectroscopy of Josephson junctions chains made from an epitaxial Al/InAs heterostructure. The chains exhibit superinductance, with characteristic wave impedanc…
Coherent and compact van der Waals transmon qubits
Jesse Balgley, Jinho Park, Xuanjing Chu +9
State-of-the-art superconducting qubits rely on a limited set of thin-film materials. Expanding their materials palette can improve performance, extend operating regimes, and intro…
Unified trajectory criterion for quantum and classical non-Markovianity
Le Hu, Archana Kamal
We propose a simple criterion for non-Markovianity: a quantum master equation is non-Markovian if and only if its \textit{trajectory set} contains a \textit{self-intersecting traje…
Tutorial: Understanding quantum Zeno and anti-Zeno regimes
Sacha Greenfield, Archana Kamal, Justin Dressel +1
The quantum Zeno effect is a striking feature of quantum mechanics with foundational implications and practical applications in quantum control, error suppression, and error correc…
Quantifying spectral signatures of non-Markovianity beyond the Born-Redfield master equation
A. Keefe, N. Agarwal, A. Kamal
Memory or time-non-local effects in open quantum dynamics pose theoretical as well as practical challenges in the understanding and control of noisy quantum systems. While there ha…
Open system dynamics in interacting quantum field theories
Brenden Bowen, Nishant Agarwal, Archana Kamal
A quantum system that interacts with an environment generally undergoes nonunitary evolution described by a non-Markovian or Markovian master equation. In this paper, we construct…
