Analog Circuit-QED Simulator of Quantum Spin Dynamics Through the Extended Bose-Hubbard Model
Ivan V. Dudinets, Jaehee Kim, Tomás Ramos +3
We propose and validate a framework for analog simulation of the Heisenberg spin model using a circuit quantum electrodynamics (circuit-QED) platform. To this end, we develop a con…
All-to-all connectivity of Rydberg-atom-based quantum processors with messenger qubits
Ivan V. Dudinets, Stanislav S. Straupe, Aleksey K. Fedorov +1
Rydberg atom arrays are a front-running platform for quantum processors. A major challenge threatening the scalability of this platform is the limited qubit connectivity due to the…
Recursion method for quench dynamics: strengths and limitations
Ilya Shirokov, Viacheslav Khrushchev, Filipp Uskov +3
The recursion method, which solves coupled Heisenberg equations in a Lanczos operator basis, has recently emerged as a powerful nonperturbative tool for computing dynamical correla…
Fermionic transport through a driven quantum point contact: breakdown of Floquet thermalization beyond a critical driving frequency
Ivan V. Dudinets, Oleg Lychkovskiy
We study a quantum system that consists of two fermionic chains coupled by a driven quantum point contact (QPC). The QPC contains a bond with a periodically varying tunneling ampli…
Entangled Probability Distributions for Center-of-Mass Tomography
Ivan V. Dudinets, Margarita A. Man'ko, Vladimir I. Man'ko
We review the formalism of center-of-mass tomograms that allows us to describe quantum states in terms of probability distribution functions. We introduce the concept of separable…
Center of mass tomography and Wigner function for multimode photon states
Ivan Dudinets, Vladimir Manko
Tomographic probability representation of multimode electromagnetic field states in the scheme of center-of-mass tomography is reviewed. Both connection of the field state Wigner f…
