Mutually unbiased bases for quantum degrees of freedom are central to all theoretical
investigations and practical exploitations of complementary properties. Much is known about …

The development of quantum walks in the context of quantum computation, as
generalisations of random walk techniques, has led rapidly to several new quantum …

Linear optics underpins fundamental tests of quantum mechanics and quantum
technologies. We demonstrate a single reprogrammable optical circuit that is sufficient to …

Quantum information theory is a branch of science at the frontier of physics, mathematics,
and information science, and offers a variety of solutions that are impossible using classical …

This book gives a unified introduction to the rapidly develo** area of finite tight frames.
Fifteen years ago, the existence of equal-norm tight frames of n> d vectors for Rd and Cd …

In Hadamard Matrices and Their Applications, KJ Horadam provides the first unified account
of cocyclic Hadamard matrices and their applications in signal and data processing. This …

This paper has two tightly intertwined aims:(i) to introduce an intuitive and universal
graphical calculus for multi-qubit systems, the ZX-calculus, which greatly simplifies …

Absolutely maximally entangled (AME) states are those multipartite quantum states that
carry absolute maximum entanglement in all possible bipartitions. AME states are known to …

Nuclear Magnetic Resonance (NMR, also known as Magnetic Resonance Spectroscopy;
MRS, in an in-vivo setting) enables one to probe the structure and dynamics of matter in a …

We consider the long-time limit of out-of-time-order correlators (OTOCs) in two classes of
quantum lattice models with time evolution governed by local unitary quantum circuits and …
