A major obstacle in the way of practical quantum computing is achieving scalable and robust high-fidelity entangling gates. To this end, quantum control has become an essential tool, as it can make the entangling interaction resilient to sources of noi…
We theoretically demonstrate a scheme to obtain an attosecond pulse train with subpetahertz helicity modulation, based on high harmonic generation driven by detuned two-color fields. As the waveform of the detuned two-color field varies with time, the …
Characterizing an isolated attosecond pulse (IAP) is essential for its potential applications. A complete characterization of an IAP ultimately requires the determination of its electric field in both time and space domains. However, previous methods, …
A scheme to entangle two cavity modes and squeeze magnon mode in a magnon–cavity QED system is presented, where the two microwave cavity modes are coupled to a massive yttrium iron garnet sphere. The nonlinearity used in our system originates from para…
In this paper, the propagation dynamics of the Pearcey Gaussian beam modeled by the fractional Schrödinger equation in linear potential have been investigated. Different from the propagation properties of the Pearcey Gaussian beam described by the stan…
We address the effects of quenched disorder averaging in the time-evolution of systems of ultracold atoms in optical lattices in the presence of noise, imposed by an environment. For bosonic systems governed by the Bose–Hubbard Hamiltonian, we quantify…
We study the possibility of generation of photo-induced image currents at a distance from the surface of nano-sized metal clusters by using the time-dependent perturbation theory. We reveal that the wave function of an electron excited to the image sta…
In order to infer the expected temperature of the two-stage cooling experiment onboard the Chinese space station (CSS) through ground experiments, we apply the direct simulation Monte Carlo algorithm to construct a simulation model suitable for both th…
Atom interferometers that employ atoms in superpositions of different electronic states are sensitive to any noise that affects these superposed states differently. Resilience to such noise results from using superpositions where the atomic states diff…
The treatment of time-dependent dynamics of quantum systems involving multiple states poses considerable technical challenges. One of the most efficient approaches in treating such systems is the Morris–Shore (MS) transformation which decomposes the mu…
