Quantum information theory is built upon the realisation that quantum resources like
coherence and entanglement can be exploited for novel or enhanced ways of transmitting …

We present a theory of the superfluid weight in multiband attractive Hubbard models within
the Bardeen-Cooper-Schrieffer (BCS) mean-field framework. We show how to separate the …

A bstract We examine the circuit complexity of coherent states in a free scalar field theory,
applying Nielsen's geometric approach as in [1]. The complexity of the coherent states have …

Multipartite entanglement is one of the core concepts in quantum information science with
broad applications that span from condensed matter physics to quantum physics foundation …

One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

Work and quantum correlations are two fundamental resources in thermodynamics and
quantum information theory. In this work, we study how to use correlations among quantum …

There is no unique and widely accepted definition of the complexity measure (CM) of a
many-fermion wave function in the presence of interactions. The simplest many-fermion …

We develop a non-adiabatic generalization of holonomic quantum computation in which
high-speed universal quantum gates can be realized using non-Abelian geometric phases …

Quantum discord quantifies nonclassical correlations in a quantum system including those
not captured by entanglement. Thus, only states with zero discord exhibit strictly classical …

We describe a multiple electronic state adaptation of the mapping approach to surface
hopping introduced recently by Mannouch and Richardson [J. Chem. Phys. 158, 104111 …
