Grid-state deformation in a no-jump non-Hermitian bosonic dimer
B. M. Rodriguez-Lara, H. Ghaemi-Dizicheh, S. Dehdashti +3
We study the no-jump evolution of ideal grid states in a lossy bosonic dimer with differential decay. The effective non-Hermitian quadratic dynamics induces a complex symplectic fl…
Generalized Kerr-Cat Qubit Codes
Alonso Viladomat, Shahram Dehdashti, Amin Kargarian +2
We present a systematic study of Schrödinger cat codes constructed from Kerr-type coherent states, including displaced Kerr coherent states and Barut--Girardello Kerr coherent sta…
Non-Hermitian three-mode couplers
B. M. Rodriguez-Lara, H. Ghaemi-Dizicheh, S. Dehdashti +3
Photonic systems with exceptional points, where eigenvalues and corresponding eigenstates coalesce, have attracted interest due to their topological features and enhanced sensitivi…
Robustness of WDM technique for the co-propagation of quantum with classical signals in an optical fiber
Sumit Chaudhary, Shahram Dehdashti, Igor Litvin +1
Many quantum communication systems operate based on weak light pulses which by design are assumed to operate in isolation from regular data traffic. With the widespread availabilit…
Higher-order exceptional points in a non-reciprocal waveguide beam splitter
Hamed Ghaemi-Dizicheh, Shahram Dehdashti, Andreas Hanke +2
Non-Hermitian systems have attracted significant interest because of their intriguing and useful properties, including exceptional points (EPs), where eigenvalues and the correspon…
