Time-optimal control fields for quantum systems with multiple avoided crossings
(American Physical Society, 2015-10)
We study time-optimal protocols for controlling quantum systems which show several avoided level crossings in their energy spectrum. The structure of the spectrum allows us to generate a robust guess which is time-optimal ...
A fractional-dimensional space approach to the study of shallow-donor states in symmetric-coupled GaAs-Ga1-xAlxAs multiple quantum wells
(Elsevier Science BvAmsterdamHolanda, 2001)
Nonlinear polaritons in II–VI MQW heterostructures
(2000)
The linear propagation of femtosecond pulses in the growth direction of excited II–VI semiconductor MQW heterostructures is studied by combining calculations of the nonlinear absorption of quantum wells from many-body ...
Classical-quantum correspondence in atomic ionization by midinfrared pulses: Multiple peak and interference structures
(American Physical Society, 2013-01)
Atomic ionization by strong and ultrashort laser pulses with frequencies in the midinfrared spectral region have revealed novel features such as the low-energy structures. We have performed fully three-dimensional quantum ...
Design Space Exploration in the Mapping of Reversible Circuits to IBM Quantum Computers
(Ieee Computer Soc, 2020-01-01)
With more and more powerful quantum computers becoming available, there is an increasing interest in the efficient mapping of a given quantum circuit to a particular quantum computer (so-called technology mapping). In most ...
Twisted deformations vs. cocycle deformations for quantum groups
(World Scientific, 2020-12-12)
In this paper we study two deformation procedures for quantum groups: deformations by twists, that we call “comultiplication twisting”, as they modify the coalgebra structure, while keeping the algebra one — and deformations ...
Multiple Quantum Wells for P T -Symmetric Phononic Crystals
(American Physical Society, 2016-11)
We demonstrate that the parity-time symmetry for sound is realized in laser-pumped multiple-quantum-well structures. Breaking of the parity-time symmetry for the phonons with wave vectors corresponding to the Bragg condition ...
