Surface charges in a Rydberg atom-nanowaveguide hybrid quantum system
Aswathy Raj, Anna Kortel, Krishna Jadeja +4
Hybrid quantum platforms based on highly excited Rydberg atoms coupled to nanophotonics devices offer a promising route toward scalable quantum networks and integrated quantum tech…
Excitation of Rb Rydberg atoms to nS and nD states (n68) via an optical nanofiber
Alexey Vylegzhanin, Dylan J. Brown, Aswathy Raj +5
Cold Rydberg atoms are a promising platform for quantum technologies and combining them with optical waveguides has the potential to create robust quantum information devices. Here…
Persistence of Topological Phases in Non-Hermitian Quantum Walks
Vikash Mittal, Aswathy Raj, Sanjib Dey +1
Discrete-time quantum walks are known to exhibit exotic topological states and phases. Physical realization of quantum walks in a noisy environment may destroy these phases. We inv…
Controlling decoherence via -symmetric non-Hermitian open quantum systems
Sanjib Dey, Aswathy Raj, Sandeep K. Goyal
We have studied the effect of a non-Hermitian Bosonic bath on the dynamics of a two-level spin system. The non-Hermitian Hamiltonian of the bath is chosen such that it converges to…
