Nonlinear dynamical Casimir effect and Unruh entanglement in waveguide QED with parametrically modulated coupling
Egor S. Vyatkin, Alexander V. Poshakinskiy, Alexander N. Poddubny
We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide. This motion can be implemented mechanically or simulated via the modulation of t…
Inverted fine structure of a 6H-SiC qubit enabling robust spin-photon interface
I. D. Breev, Z. Shang, A. V. Poshakinskiy +11
Optically controllable solid-state spin qubits are one of the basic building blocks for applied quantum technology. Efficient extraction of emitted photons and a robust spin-photon…
Dimerization of many-body subradiant states in waveguide quantum electrodynamics
Alexander V. Poshakinskiy, Alexander N. Poddubny
We study theoretically subradiant states in the array of atoms coupled to photons propagating in a one-dimensional waveguide focusing on the strongly interacting many-body regime w…
Quantum chaos driven by long-range waveguide-mediated interactions
Alexander V. Poshakinskiy, Janet Zhong, Alexander N. Poddubny
We study theoretically quantum states of a pair of photons interacting with a finite periodic array of two-level atoms in a waveguide. Our calculation reveals two-polariton eigenst…
Radiative topological biphoton states in modulated qubit arrays
Yongguan Ke, Janet Zhong, Alexander V. Poshakinskiy +3
We study topological properties of bound pairs of photons in spatially-modulated qubit arrays (arrays of two-level atoms) coupled to a waveguide. While bound pairs behave like Bloc…
Photon-mediated localization in two-level qubit arrays
Janet Zhong, Nikita A. Olekhno, Yongguan Ke +4
We predict the existence of a novel interaction-induced spatial localization in a periodic array of qubits coupled to a waveguide. This localization can be described as a quantum a…
