Resonances control when multiterminal Josephson currents reduce to two-terminal couplings
A. Barış Özgüler
Multiterminal Josephson junctions, in which one weak link couples three or more superconductors, are studied as hosts of topological Andreev bands, multi-pair supercurrents and tun…
Performance evaluation of variational quantum eigensolver and quantum dynamics algorithms on the advection-diffusion equation
A. Barış Özgüler
Near-term quantum algorithms are a promising route to solving partial differential equations, but gauging their true potential requires separating algorithmic performance from samp…
Dynamics of qudit gates and effects of spectator modes on optimal control pulses
A. Barış Özgüler, Joshua A. Job
Qudit gates for high-dimensional quantum computing can be synthesized with high precision using numerical quantum optimal control techniques. Large circuits are broken down into mo…
Numerical Gate Synthesis for Quantum Heuristics on Bosonic Quantum Processors
A. Barış Özgüler, Davide Venturelli
There is a recent surge of interest and insights regarding the interplay of quantum optimal control and variational quantum algorithms. We study the framework in the context of qud…
Benchmarking variational quantum eigensolvers for the square-octagon-lattice Kitaev model
Andy C. Y. Li, M. Sohaib Alam, Thomas Iadecola +8
Quantum spin systems may offer the first opportunities for beyond-classical quantum computations of scientific interest. While general quantum simulation algorithms likely require…
Impacts of Noise and Structure on Quantum Information Encoded in a Quantum Memory
Matthew Otten, Keshav Kapoor, A. Barış Özgüler +4
As larger, higher-quality quantum devices are built and demonstrated in quantum information applications, such as quantum computation and quantum communication, the need for high-q…
Response of a quantum disordered spin system to a local periodic drive
A. Barış Özgüler, Canran Xu, Maxim G. Vavilov
We consider a one-dimensional spin chain system with quenched disorder and in the presence of a local periodic drive. We study the time evolution of the system in the Floquet basis…
Steering random spin systems to speed up the quantum adiabatic algorithm
A. Barış Özgüler, Robert Joynt, Maxim G. Vavilov
A general time-dependent quantum system can be driven fast from its initial ground state to its final ground state without generating transitions by adding a steering term to the H…
