As we begin to reach the limits of classical computing, quantum computing has emerged as
a technology that has captured the imagination of the scientific world. While for many years …

Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

Quantum computing (QC) stands apart from traditional computing systems by employing
revolutionary techniques for processing information. It leverages the power of quantum bits …

Digital quantum computers provide a computational framework for solving the Schrödinger
equation for a variety of many‐particle systems. Quantum computing algorithms for the …

The operator entanglement (OE) is a key quantifier of the complexity of a reduced density
matrix. In out-of-equilibrium situations, eg, after a quantum quench of a product state, it is …

We show that a micromaser is an excellent model of quantum battery. A highly excited, pure,
and effectively steady state of the cavity mode, charged by coherent qubits, can be achieved …

Quantum computing is considered as a next-generation information processing technology.
The basic element of a quantum computing system is a quantum bit, often called a qubit …

The many-body physics at quantum phase transitions shows a subtle interplay between
quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we …

We study the dynamics of entanglement in the quantum Ising chain with dephasing
dissipation in a Lindblad master equation form. We consider two unravelings which preserve …

Energy transfer in small nano-sized systems can be very different from that in their
macroscopic counterparts due to reduced dimensionality, interaction with surfaces, disorder …
