Special Issue Information

The idea of harnessing the laws of quantum physics for information storage, transfer, and processing have been around for some forty years. In addition to theoretically exploring the new possibilities, great effort has been devoted to the experimental realizations of theoretical proposals. There are several fields of experimental physics where researchers have been developing devices. It has turned out that photons and interaction between photons and atoms, or nano- or mezo-scale atomic systems, play a central role in actual practical realizations. This research field is precisely the scope of Quantum Optics. In this Special Issue, we would like to collect research papers which describe quantum information storage, transfer or processing schemes or devices whose working principle lays in the field of Quantum Optics.

In this article, we evaluate the efficiency of two shortcuts to adiabaticity for the STIRAP system, in the presence of Ornstein–Uhlenbeck noise in the energy levels. The shortcuts under consideration preserve the interactions of the original Hamiltonian, without adding extra counterdiabatic terms, which directly connect the initial and target states. The first shortcut is such that the mixing angle is a polynomial function of time, while the second shortcut is derived from Gaussian pulses. Extensive numerical simulations indicate that both shortcuts perform quite well and robustly even in the presence of relatively large noise amplitudes, while their performance is decreased with increasing noise correlation time. For similar pulse amplitudes and durations, the efficiency of classical STIRAP is highly degraded even in the absence of noise. When using pulses with similar areas for the two STIRAP shortcuts, the shortcut derived from Gaussian pulses appears to be more efficient. Since STIRAP is an essential tool for the implementation of emerging quantum technologies, the present work is expected to find application in this broad research field. Full article
