Three Qubit Randomized Benchmarking
David C. McKay, Sarah Sheldon, John A. Smolin +2
As quantum circuits increase in size, it is critical to establish scalable multiqubit fidelity metrics. Here we investigate three-qubit randomized benchmarking (RB) with fixed-freq…
Quantum optimization using variational algorithms on near-term quantum devices
Nikolaj Moll, Panagiotis Barkoutsos, Lev S. Bishop +15
Universal fault-tolerant quantum computers will require error-free execution of long sequences of quantum gate operations, which is expected to involve millions of physical qubits.…
Quantifying Coherence and Entanglement via Simple Measurements
Graeme Smith, John A. Smolin, Xiao Yuan +3
Coherence and entanglement are fundamental properties of quantum systems, promising to power the near future quantum computers, sensors and simulators. Yet, their experimental dete…
Open Quantum Assembly Language
Andrew W. Cross, Lev S. Bishop, John A. Smolin +1
This document describes a quantum assembly language (QASM) called OpenQASM that is used to implement experiments with low depth quantum circuits. OpenQASM represents universal phys…
