In this review recent investigations are summarized of many-body quantum systems with
long-range interactions, which are currently realized in Rydberg atom arrays, dipolar …

Adiabatic quantum computing (AQC) started as an approach to solving optimization
problems and has evolved into an important universal alternative to the standard circuit …

Quantum annealing is a new-generation tool of information technology, which helps in
solving combinatorial optimization problems with high precision, based on the concepts of …

Among various algorithms designed to exploit the specific properties of quantum computers
with respect to classical ones, the quantum adiabatic algorithm is a versatile proposition to …

We study first-order quantum phase transitions in models where the mean-field treatment is
exact, and in particular the exponentially fast closure of the energy gap with the system size …

This paper deals with fully connected mean-field models of quantum spins with p-body
ferromagnetic interactions and a transverse field. For p= 2 this corresponds to the quantum …

We derive a systematic approach to the thermodynamics of quantum systems based on the
underlying symmetry groups. We first show that the entropy of a system can be described in …

The cavity method is a well-established technique for solving classical spin models on
sparse random graphs (mean-field models with finite connectivity). Laumann [Phys. Rev. B …

Quantum annealing correction (QAC) is a method that combines encoding with energy
penalties and decoding to suppress and correct errors that degrade the performance of …
