The mathematics of optimal control of quantum systems is of great interest in connection with
fundamental problems of physics as well as with existing and prospective applications to …

All quantum systems are subject to noise from the environment or external controls. This
noise is a major obstacle to the realization of quantum technology. For example, noise limits …

In this work we analyze the implementation of a control-phase gate through the resonance
between the∣ 11⟩ and∣ 20⟩ states of two statically coupled transmons. We find that there …

We examine the effectiveness and resilience of achieving quantum gates employing three
approaches stemming from quantum control methods: counterdiabatic driving, Floquet …

The density matrix is a widely used tool in quantum mechanics. In order to determine its
evolution with respect to time, the Liouville-von Neumann equation must be solved …

With this special issue of the European Physical Journal B we pay homage to the scientific
career of Eberhard Kurt Ulrich (Hardy) Gross (see Fig. 1), on occasion of his 65th birthday …

Математические задачи оптимального управления квантовыми системами привлекают
высокий интерес в связи как с фундаментальными проблемами физики, так и с …

Quantum cascade lasers (QCLs) are relatively novel sources of mid-infrared and terahertz
radiation. In their envisaged applications advanced operating modes, such as frequency …

Optimal two-qubit operation is of significance to quantum information processing. An efficient
scheme is proposed for realizing the shortcut to adiabatic two-qubit state swap in a …
