Optically-Heralded Entanglement of Superconducting Systems in Quantum Networks
Stefan Krastanov, Hamza Raniwala, Jeffrey Holzgrafe +4
Networking superconducting quantum computers is a longstanding challenge in quantum science. The typical approach has been to cascade transducers: converting to optical frequencies…
Matchgate benchmarking: Scalable benchmarking of a continuous family of many-qubit gates
Jonas Helsen, Sepehr Nezami, Matthew Reagor +1
We propose a method to reliably and efficiently extract the fidelity of many-qubit quantum circuits composed of continuously parametrized two-qubit gates called matchgates. This me…
Estimating expectation values using approximate quantum states
Marco Paini, Amir Kalev, Dan Padilha +1
We introduce an approximate description of an -qubit state, which contains sufficient information to estimate the expectation value of any observable to a precision that is uppe…
Quantum limits on noise for a class of nonlinear amplifiers
Jeffrey M. Epstein, K. Birgitta Whaley, Joshua Combes
Nonlinear amplifiers such as the transistor are ubiquitous in classical technology, but their quantum analogues are not well understood. We introduce a class of nonlinear amplifier…
Deconvolving Pulsar Signals with Cyclic Spectroscopy: A Systematic Evaluation
Timothy Dolch, Daniel R. Stinebring, Glenn Jones +8
Radio pulsar signals are significantly perturbed by their propagation through the ionized interstellar medium. In addition to the frequency-dependent pulse times of arrival due to…
Observation of Weyl fermions in a magnetic non-centrosymmetric crystal
Daniel S. Sanchez, Guoqing Chang, Ilya Belopolski +15
Characterized by the absence of inversion symmetry, non-centrosymmetric materials are of great interest because they exhibit ferroelectricity, second harmonic generation, emergent…
