Scaling the Automated Discovery of Quantum Circuits via Reinforcement Learning with Gadgets
Jan Olle, Oleg M. Yevtushenko, Florian Marquardt
Reinforcement Learning (RL) has established itself as a powerful tool for designing quantum circuits, which are essential for processing quantum information. RL applications have t…
Localization, fractality, and ergodicity in a monitored qubit
Paul Pöpperl, Igor V. Gornyi, David B. Saakian +1
We study the statistical properties of a single two-level system (qubit) subject to repetitive ancilla-based measurements. This setup is a fundamental minimal model for exploring t…
RKKY to Kondo crossover in Helical Edge of a Topological Insulator
Pol Alonso-Cuevillas Ferrer, Oleg M. Yevtushenko, Andreas Weichselbaum
Two spatially separated magnetic impurities coupled to itinerant electrons give rise to a dynamically generated exchange (RKKY) inter-impurity interaction that competes with the in…
Semiconductor-based electron flying qubits: Review on recent progress accelerated by numerical modelling
Hermann Edlbauer, Junliang Wang, Thierry Crozes +20
The progress of charge manipulation in semiconductor-based nanoscale devices opened up a novel route to realise a flying qubit with a single electron. In the present review, we int…
Suppression of ballistic helical transport by isotropic dynamical magnetic impurities
Oleg M. Yevtushenko, Vladimir I. Yudson
Dynamical magnetic impurities (MI) are considered as a possible origin for suppression of the ballistic helical transport on edges of 2D topological insulators. The MIs provide a s…
Protected helical transport in magnetically doped quantum wires: Beyond the one-dimensional paradigm
F. Stäbler, A. M. Tsvelik, O. M. Yevtushenko
One-dimensional (1D) quantum wires, which are functionalized by magnetic ad-atoms, can host ballistic helical transport. Helicity protects transport from an undesirable influence o…
