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…
An Open-Source, Industrial-Strength Optimizing Compiler for Quantum Programs
Robert S. Smith, Eric C. Peterson, Mark G. Skilbeck +1
Quilc is an open-source, optimizing compiler for gate-based quantum programs written in Quil or QASM, two popular quantum programming languages. The compiler was designed with atte…
A quantum-classical cloud platform optimized for variational hybrid algorithms
Peter J. Karalekas, Nikolas A. Tezak, Eric C. Peterson +3
In order to support near-term applications of quantum computing, a new compute paradigm has emerged--the quantum-classical cloud--in which quantum computers (QPUs) work in tandem w…
