Pre- and post-selection paradoxes in quantum walks
Autor: T Kopyciuk, M Lewandowski, P Kurzyński
Publikováno v: New Journal of Physics, Vol 21, Iss 10, p 103054 (2019)
Many features of single-partite quantum walks can be simulated by classical waves. However, it was recently experimentally shown that some temporal sequences of measurements on a quantum walker do not admit a classical description in terms of macro-r

Nonclassical oscillations in pre- and post-selected quantum walks
Autor: T. Kopyciuk, Xiao-Xiao Chen, Jia-Zhi Yang, Jian Li, Zhe Meng, Paweł Kurzyński, An-Ning Zhang
Quantum walks are counterparts of classical random walks. They spread faster, which can be exploited in information processing tasks, and constitute a versatile simulation platform for many quantum systems. Yet, some of their properties can be emulat

Deexcitation of one-dimensional Rydberg atoms with a chirped train of half-cycle pulses
Autor: T. Kopyciuk
Publikováno v: Physics Letters A. 374:3464-3467
A protocol for deexcitation of one-dimensional high Rydberg states with the use of a chirped train of half-cycle pulses is given. It is found that the parameters of the efficiently deexciting train are directly related to the phenomenon of the dynami

Localization of a half-cycle pulse-induced Rydberg wave packet in phase space: An analytical description
Autor: M. Sobczak, T. Kopyciuk, R. Parzyński
Publikováno v: Physics Letters A. 352:505-510
We calculate analytically the position–momentum uncertainty product for a freely evolving wave packet produced by a unidirectional half-cycle pulse (HCP) or a pair of HCP's in a one-dimensional (1D) hydrogen atom. Our analytical treatment is shown
