Unified Theory of Ghost Imaging with Gaussian-State Light
Baris I. Erkmen, Jeffrey H. Shapiro
The theory of ghost imaging is developed in a Gaussian-state framework that both encompasses prior work - on thermal-state and biphoton-state imagers - and provides a complete unde…
The Entropy Photon-Number Inequality and its Consequences
Saikat Guha, Baris I. Erkmen, Jeffrey H. Shapiro
Determining the ultimate classical information carrying capacity of electromagnetic waves requires quantum-mechanical analysis to properly account for the bosonic nature of these w…
Classical capacity of bosonic broadcast communication and a new minimum output entropy conjecture
Saikat Guha, Jeffrey H. Shapiro, Baris I. Erkmen
Previous work on the classical information capacities of bosonic channels has established the capacity of the single-user pure-loss channel, bounded the capacity of the single-user…
Classical Information Capacity of the Bosonic Broadcast Channel
Saikat Guha, Jeffrey H. Shapiro
We show that when coherent-state encoding is employed in conjunction with coherent detection, the Bosonic broadcast channel is equivalent to a classical degraded Gaussian broadcast…
Continuous-time cross-phase modulation and quantum computation
Jeffrey H. Shapiro, Mohsen Razavi
The weak nonlinear Kerr interaction between single photons and intense laser fields has been recently proposed as a basis for distributed optics-based solutions to few-qubit applic…
