The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

The efficiency of the future devices for quantum information processing is limited mostly by
the finite decoherence rates of the individual qubits and quantum gates. Recently …

Remarkable progress towards realizing quantum computation has been achieved using
natural and artificial atoms as qubits. This paper presents a brief overview of the current …

We present a general method to efficiently design optimal control sequences for non-
Markovian open quantum systems, and illustrate it by optimizing the shape of a laser pulse …

We study the limits of bipartite entanglement distribution using a chain of quantum repeaters
that have quantum memories. To generate end-to-end entanglement, each node can …

Single photons, often called flying qubits, have enormous promise to realize scalable
quantum technologies ranging from an unhackable communication network to quantum …

Non-Markovian dynamics arising from the strong coupling of a system to a structured
environment is essential in many applications of quantum mechanics and emerging …

As Hamiltonian models underpin the study and analysis of physical and chemical
processes, it is crucial that they are faithful to the system they represent. However …

Single photon emission (SPE) by a solid-state source requires presence of a distinct two-
level quantum system, usually provided by point defects. Here we note that a number of …

The goal of this article is to review the progress of three-electron spin qubits from their
inception to the state of the art. We direct the main focus towards the exchange-only qubit …
