Photonic quantum technologies represent a promising platform for several applications,
ranging from long-distance communications to the simulation of complex phenomena …

In this short review article, we aim to provide physicists not working within the quantum
computing community a hopefully easy-to-read introduction to the state of the art in the field …

Abstract Noisy Intermediate-Scale Quantum (NISQ) technology will be available in the near
future. Quantum computers with 50-100 qubits may be able to perform tasks which surpass …

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 …

Quantum software plays a critical role in exploiting the full potential of quantum computing
systems. As a result, it has been drawing increasing attention recently. This paper defines …

In this article, we review strong light-matter coupling at the interface of materials science,
quantum chemistry, and quantum photonics. The control of light and heat at thermodynamic …

To obtain estimates of electronic energies, the Variational Quantum Eigensolver (VQE)
technique performs separate measurements for multiple parts of the system Hamiltonian …

Quantum mechanics, the subfield of physics that describes the behavior of very small
(quantum) particles, provides the basis for a new paradigm of computing. First proposed in …

Quantum computers are available to use over the cloud, but the recent explosion of quantum
software platforms can be overwhelming for those deciding on which to use. In this paper …

A central component of variational quantum algorithms (VQAs) is the state-preparation
circuit, also known as ansatz or variational form. This circuit is most commonly designed …
