A universal fault-tolerant quantum computer that can efficiently solve problems such as
integer factorization and unstructured database search requires millions of qubits with low …

Advances in isolating, controlling and entangling quantum systems are transforming what
was once a curious feature of quantum mechanics into a vehicle for disruptive scientific and …

Quantum assembly languages are machine-independent languages that traditionally
describe quantum computation in the circuit model. Open quantum assembly language …

This document describes a quantum assembly language (QASM) called OpenQASM that is
used to implement experiments with low depth quantum circuits. OpenQASM represents …

Dynamical decoupling (DD) is perhaps the simplest and least resource-intensive error-
suppression strategy for improving quantum computer performance. Here we report on a …

Quantum computers may provide good solutions to combinatorial optimization problems by
leveraging the Quantum Approximate Optimization Algorithm (QAOA). The QAOA is often …

Quantum volume (QV) has become the de-facto standard benchmark to quantify the
capability of noisy intermediate-scale quantum (NISQ) devices. While QV values are often …

There is an increasing interest in quantum algorithms for problems of integer programming
and combinatorial optimization. Classical solvers for such problems employ relaxations …

Quantum computers promise tremendous impact across applications—and have shown
great strides in hardware engineering—but remain notoriously error prone. Careful design of …

We introduce Mitiq, a Python package for error mitigation on noisy quantum computers. Error
mitigation techniques can reduce the impact of noise on near-term quantum computers with …
