The variational quantum eigensolver (or VQE), first developed by Peruzzo et al.(2014), has
received significant attention from the research community in recent years. It uses the …

As we begin to reach the limits of classical computing, quantum computing has emerged as
a technology that has captured the imagination of the scientific world. While for many years …

Quantum information processing is steadily progressing from a purely academic discipline
towards applications throughout science and industry. Transitioning from lab-based, proof-of …

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 …

Quantum simulation of chemistry and materials is predicted to be an important application
for both near-term and fault-tolerant quantum devices. However, at present, develo** and …

We report the first electronic structure calculation performed on a quantum computer without
exponentially costly precompilation. We use a programmable array of superconducting …

Using quantum devices supported by classical computational resources is a promising
approach to quantum-enabled computation. One powerful example of such a hybrid …

In this work we investigate methods to improve the efficiency and scalability of quantum
algorithms for quantum chemistry applications. We propose a transformation of the …

Limited quantum memory is one of the most important constraints for near-term quantum
devices. Understanding whether a small quantum computer can simulate a larger quantum …

We discuss encodings of fermionic many-body systems by qubits in the presence of
symmetries. Such encodings eliminate redundant degrees of freedom in a way that …
