Our world, of course, changed in many other ways as well since the publication of the first
edition. The global pandemic impacted all areas of society and will probably transform how …

Recent work has explored using the stabilizer formalism to classically simulate quantum
circuits containing a few non-Clifford gates. The computational cost of such methods is …

Tensor networks represent the state-of-the-art in computational methods across many
disciplines, including the classical simulation of quantum many-body systems and quantum …

Abstract We introduce Strawberry Fields, an open-source quantum programming
architecture for light-based quantum computers, and detail its key features. Built in Python …

Abstract We introduce QuEST, the Quantum Exact Simulation Toolkit, and compare it to
ProjectQ, qHipster and a recent distributed implementation of Quantum++. QuEST is the first …

Hybrid quantum/classical variational algorithms can be implemented on noisy intermediate-
scale quantum computers and can be used to find solutions for combinatorial optimization …

We present Qibo, a new open-source software for fast evaluation of quantum circuits and
adiabatic evolution which takes full advantage of hardware accelerators. The growing …

Classical simulation of quantum computers will continue to play an essential role in the
progress of quantum information science, both for numerical studies of quantum algorithms …

In this paper, we eliminate the classical outer learning loop of the quantum approximate
optimization algorithm (QAOA) and present a strategy to find good parameters for QAOA …

Integer factorization has been one of the cornerstone applications of the field of quantum
computing since the discovery of an efficient algorithm for factoring by Peter Shor …
