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…
Energy-Efficient Satellite Wake-Up via Bosonic Identification: The Role of Synchronization
Gökhan Elmas, Janis Nötzel
The information-theoretic concept of identification describes a sender-receiver architecture in which the receiver only checks whether a particular message was sent or not, thereby…
Fundamental Limits of Eavesdropper Detection and Localization in Optical Fiber via Stimulated Brillouin Scattering
Kiran Adhikari, Janis Nötzel
Recent work investigated the use of Stimulated Brillouin Scattering (SBS) to measure changes in fiber parameters, thereby enhancing the security of a Quantum Key Distribution (QKD)…
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…
Private Communication over a Bosonic Compound Channel
Florian Seitz, Matteo Rosati, Ãngeles Vázquez-Castro +1
It is a common belief that quantum key distribution systems are the one and only information-theoretically secure physical layer security protocol that enables secure data transmis…
