Quantum dynamics of two interacting PT-symmetric non-Hermitian qubits: enhancement of quantum annealing
Yana Komissarova, Mikhail V. Fistul, Ilya M. Eremin
Quantum information platforms enable analog quantum simulations, such as quantum annealing, offering a promising route to solving complex combinatorial optimization problems. Here,…
Nematic Phase Transitions in 1D Flat Band Condensates
Yeongjun Kim, Oleg I. Utesov, Alexei Andreanov +2
We investigate the ground-state properties of one-dimensional Gross-Pitaevskii flat-band lattices which are parametrized through their compact localized state (CLS) amplitudes. We…
Bose condensation and Bogoliubov excitation in resonator-embedded superconducting qubit network
Patrick Navez, Valentina Di Meo, Berardo Ruggiero +12
Superconducting qubit networks (SQNs) embedded in a low-dissipative resonator is a promising device allowing one not only to establish the collective quantum dynamics on a macrosco…
Time molecules with periodically driven interacting qubits
K. V. Shulga, I. Vakulchyk, Y. Nakamura +2
We provide numerical evidence for a temporal quantum-mechanical interference phenomenon: time molecules (TM). A variety of such stroboscopic states are observed in the dynamics of…
