All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Catalysts open up new reaction pathways that can speed up chemical reactions while not
consuming the catalyst. A similar phenomenon has been discovered in quantum information …

Note from the Research Highlights Co-Chairs: A Research Highlights paper appearing in
Communications is usually peer-reviewed prior to publication. The following paper is …

Quantum information processing is the emerging field that defines and realizes computing
devices that make use of quantum mechanical principles such as the superposition …

The last decade has witnessed remarkable progress in the development of quantum
technologies. Although fault-tolerant devices likely remain years away, the noisy …

Quantum computers promise to efficiently solve not only problems believed to be intractable
for classical computers, but also problems for which verifying the solution is also considered …

This article surveys quantum computational complexity, with a focus on three fundamental
notions: polynomial-time quantum computations, the efficient verification of quantum proofs …

Nonlocality was discovered by John Bell in 1964, in the context of the debates about
quantum theory, but is a phenomenon that can be studied in its own right. Its observation …

Following the first paper on quantum algorithms for SDP-solving by Brand\~ ao and Svore in
2016, rapid developments has been made on quantum optimization algorithms. Recently …

Over 50 years ago, Lovász proved that two graphs are isomorphic if and only if they admit
the same number of homomorphisms from any graph. Other equivalence relations on …
