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…
Testing eigenstate decoherence hypothesis in a model of collisional decoherence
Ivan V. Dudinets, Igor Ermakov, Oleg Lychkovskiy
The eigenstate decoherence hypothesis (EDH) asserts that each individual eigenstate of a large closed system is locally classical-like. We test this hypothesis for a heavy particle…
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…
Tomography on f-oscillators
I. V. Dudinets, V. I. Man'ko, G. Marmo +1
Symplectic tomographies of classical and quantum states are shortly reviewed. The concept of nonlinear f-oscillators and their properties are recalled. The tomographic probability…
The replica method and entropy for mixture of two-mode even and odd schrödinger cat states
Ivan V. Dudinetc, Vladimir I. Man'ko
The replica method for calculating the von Neumann entropy is reviewed. Explicit expression for the entropy of the mixed coherent states and is obtained using this meth…
