Chapter 45. Optical and Quantum Communications Optical and Quantum Communications
The central theme of our programs has been to advance the understanding of optical and quantum communication, radar, and sensing systems. Broadly speaking, this has entailed: (1) developing system-analytic models for important propagation, detection, and communication scenarios; (2) using these models to derive the fundamental limits on system performance; and (3) identifying, and establishing ...

متن کاملQuantum communications and beyond.
We introduce the concept of encoding and manipulation of information on single photons. This is exploited in the technique of quantum cryptography to distribute random bit strings in a secure way. More general quantum information processing requires a conditional interaction between separate photons. This can be achieved by exploiting the interference between two photons at a beam-splitter and ...
متن کاملQuantum Superluminal Communications Michai
Quantum nonlocality arising from entasgled states is the most fundamental and the most mysterious phenomenon in quantum mechanics, and it is in the core of quantum information theory. Fomally quantum nonlocality follows from the SchrMinger equation; however, its physical meaning is still unclear despite successful experimental confirmation,"] and applications to teleportation, cryptography and...
متن کاملExperimental Satellite Quantum Communications.
Quantum communication (QC), namely, the faithful transmission of generic quantum states, is a key ingredient of quantum information science. Here we demonstrate QC with polarization encoding from space to ground by exploiting satellite corner cube retroreflectors as quantum transmitters in orbit and the Matera Laser Ranging Observatory of the Italian Space Agency in Matera, Italy, as a quantum ...
