Quantum technologies represent a rapidly evolving field in which the specific properties of
quantum mechanical systems are exploited to enhance the performance of various …

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 …

The aim of this review is to provide quantum engineers with an introductory guide to the
central concepts and challenges in the rapidly accelerating field of superconducting …

Quantum coherence in natural and artificial spin systems is fundamental to applications
ranging from quantum information science to magnetic-resonance imaging and …

Decoherence in quantum bit circuits is presently a major limitation to their use for quantum
computing purposes. We present experiments, inspired from NMR, that characterize …

We theoretically investigate the influence of designed pulse sequences in restoring quantum
coherence lost due to background noise in superconducting qubits. We consider both 1/f …

Accurate characterization of the noise influencing a quantum system of interest has far-
reaching implications across quantum science, ranging from microscopic modeling of …

The interaction of solid-state qubits with environmental degrees of freedom strongly affects
the qubit dynamics, and leads to decoherence. In quantum information processing with solid …

We analyze and compare three different strategies, all aimed at controlling and eventually
halting decoherence. The first strategy hinges upon the quantum Zeno effect, the second …

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 …
