Line defects in infinite networks of resistors
Róbert Németh, József Cserti, Gábor Széchenyi
We study infinite resistor networks perturbed by line defects, in which the resistances are periodically modified along a single line. Using the Sherman-Morrison identity applied t…

Training iterated protocols for distillation of GHZ states with variational quantum algorithms
Áron Rozgonyi, Gábor Széchenyi, Orsolya Kálmán +1
We present optimized distillation schemes for preparing Greenberger-Horne-Zeilinger (GHZ) states. Our approach relies on training variational quantum circuits with white noise affe…

Bichromatic Rabi Control of Semiconductor Qubits
Valentin John, Francesco Borsoi, Zoltán György +9
Electrically driven spin resonance is a powerful technique for controlling semiconductor spin qubits. However, it faces challenges in qubit addressability and off-resonance driving…
