Over the past several decades, quantum information science has emerged to seek answers
to the question: can we gain some advantage by storing, transmitting and processing …

How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

One of the key applications for quantum computers will be the simulation of other quantum
systems that arise in chemistry, materials science, etc., in order to accelerate the process of …

Key static and dynamic properties of matter—from creation in the Big Bang to evolution into
subatomic and astrophysical environments—arise from the underlying fundamental …

Gate set tomography (GST) is a protocol for detailed, predictive characterization of logic
operations (gates) on quantum computing processors. Early versions of GST emerged …

Quantum simulators are controllable quantum systems that can be used to simulate other
quantum systems. Being able to tackle problems that are intractable on classical computers …

Quantum control is concerned with active manipulation of physical and chemical processes
on the atomic and molecular scale. This work presents a perspective of progress in the field …

Quantum computers are poised to radically outperform their classical counterparts by
manipulating coherent quantum systems. A realistic quantum computer will experience …

Noise is the central obstacle to building large-scale quantum computers. Quantum systems
with sufficiently uncorrelated and weak noise could be used to solve computational …

Quantum computers can now run interesting programs, but each processor's capability—the
set of programs that it can run successfully—is limited by hardware errors. These errors can …
