Quantum dynamics of semiconductor quantum dot Josephson junctions
Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3
Josephson junctions constructed from superconductor-semiconductor-superconductor heterostructures have been used to realize a variety of voltage-tunable superconducting quantum dev…
Nonadiabatic quantum control of quantum dot arrays with fixed exchange using Cartan decomposition
David W. Kanaar, Utkan Güngördü, J. P. Kestner
In semiconductor spin qubits which typically interact through short-range exchange coupling, shuttling of spin is a practical way to generate quantum operations between distant qub…
Majorana bound states with chiral magnetic textures
Utkan Güngördü, Alexey A. Kovalev
The aim of this Tutorial is to give a pedagogical introduction into realizations of Majorana fermions, usually termed as Majorana bound states (MBS), in condensed matter systems wi…
Two-qubit CZ gates robust against charge noise in silicon while compensating for crosstalk using neural network
David W. Kanaar, Utkan Güngördü, J. P. Kestner
The fidelity of two-qubit gates using silicon spin qubits is limited by charge noise. When attempting to dynamically compensate for charge noise using local echo pulses, crosstalk…
Robust quantum gates using smooth pulses and physics-informed neural networks
Utkan Güngördü, J. P. Kestner
The presence of decoherence in quantum computers necessitates the suppression of noise. Dynamically corrected gates via specially designed control pulses offer a path forward, but…
Simulated Randomized Benchmarking of a Dynamically Corrected Cross-Resonance Gate
R. K. L. Colmenar, Utkan Güngördü, J. P. Kestner
We theoretically consider a cross-resonance (CR) gate implemented by pulse sequences proposed by Calderon-Vargas & Kestner, Phys. Rev. Lett. 118, 150502 (2017). These sequences mit…
