Informational Mpemba Effect for Fast State Purification in Non-Hermitian System
C. G. Feyisa, Huan-Yu Ku, J. -S. You +1
Quantum systems are inherently fragile to environmental fluctuations or decoherence, limiting their advantages in applications of quantum information and quantum computation. State…
Excitation transfer and many-body dark states in waveguide quantum electrodynamics
Wei Chen, Guin-Dar Lin, H. H. Jen
In one-dimensional waveguide quantum electrodynamics systems, quantum emitters interact through infinite-range, dispersive, and dissipative dipole-dipole interactions mediated by g…
High-fidelity multipartite entanglement creation in non-Hermitian qubits
C. -Y. Liu, C. G. Feyisa, Muhammad S. Hasan +1
Non-Hermitian quantum systems showcase many distinct and intriguing features with no Hermitian counterparts. One of them is the exceptional point which marks the PT (parity and tim…
Robustness of tripartite entangled states in passive PT-symmetric qubits
C. G. Feyisa, Cheng-Yu Liu, Muhammad S. Hasan +3
Non-Hermitian quantum systems have attracted significant interest in recent years due to the presence of unique spectral singularities known as exceptional points (EPs), where eige…
Accelerating multipartite entanglement generation in non-Hermitian superconducting qubits
Chimdessa Gashu Feyisa, J. S. You, Huan-Yu Ku +1
Open quantum systems are susceptible to losses in information, energy, and particles due to their surrounding environment. One novel strategy to mitigate these losses is to transfo…
