DOI: 10.1007/s11587-021-00662-5
Abstract: In this paper, we first introduce four new generalized quantum integrals of two variables functions which are called $$T_{q}$$ -integrals. We also give some examples of each of these given integrals. Then we establish corresponding… read more here.

DOI: 10.1103/physreva.104.052417
Abstract: Variational quantum algorithms that are used for quantum machine learning rely on the ability to automatically differentiate parametrized quantum circuits with respect to underlying parameters. Here, we propose the rules for differentiating quantum circuits (unitaries)… read more here.

DOI: 10.1142/s0217751x20501791
Abstract: In this work we study the Higgs mechanism and the Debye shielding for the Bopp–Podolsky theory of electrodynamics. We find that not only the massless sector of the Podolsky theory acquires a mass in both… read more here.

DOI: 10.1364/oe.487883
Abstract: Nonlocal observables of spacelike separated quantum systems in combination with their measurements contribute greatly to quantum theory and its applications. We present a nonlocal generalized quantum measurement protocol for measuring product observables, assisted by a… read more here.
