We calculate the communication capacity of a broadband electromagnetic waveguide as a function of its spatial dimensions and input power. We analyze the two cases in which either all the available modes or only a single directional mode are employed. The results are compared with those for the free-space bosonic channel.

Analysis of a single-mode waveguide at sub-terahertz frequencies as a communication channel

We study experimentally the transmission of an electromagnetic waveguide in the frequency range from 160 to 300 GHz. Photo-mixing is used to excite and detect the fundamental TE10 mode in a

Capacities of linear quantum optical systems

This work focuses on communication of classical information, the extension to quantum information being straightforward, and shows that diffraction is formally described as a memory channel.

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

Enhanced quantum communication via optical refocusing

We consider the problem of quantum communication mediated by a passive optical refocusing system. The model captures the basic features of all those situations in which a signal is either refocused

A general framework is proposed which makes use of a natural underlying symplectic structure, to relate the entropy of a quantum mesoscopic system to the scattering matrix.

The physical limits of communication or Why any sufficiently advanced technology is indistinguishable from noise

It is shown that if electromagnetic radiation is used as a transmission medium, the most information-efficient format for a given message is indistinguishable from blackbody radiation.

It has recently been suggested in this journal by Benford that “Lurkers” in the form of interstellar exploration probes could be present in the solar system. Similarly, extraterrestrial intelligence

Broadband channel capacities

We study the communication capacities of bosonic broadband channels in the presence of different sources of noise. In particular we analyze lossy channels in the presence of white noise and thermal

Entanglement assisted capacity of the broadband Lossy channel.

The entanglement assisted capacity of a multimode bosonic channel with loss is calculated, where the superdense coding effect can be used to transmit more bits than those that can be stored in the message sent down the channel.

Classical capacity of the lossy bosonic channel: the exact solution.

The classical capacity of the lossy bosonic channel is calculated exactly. It is shown that its Holevo information is not superadditive, and that a coherent-state encoding achieves capacity. The

It is shown that the capacity of a classical-quantum channel with arbitrary (possibly mixed) states equals the maximum of the entropy bound with respect to all a priori distributions. This completes

Quantum limits on bosonic communication rates

The capacity C of a communication channel is the maximum rate at which information can be transmitted without error from the channel's input to its output. The authors review quantum limits on the

The possible amount of information transfer between any source and any user via a quantum system is bounded through the quantum entropy function, which shows that infinite information transfer implies infinite entropy.

The quantum analog of the classical paraxial diffraction theory for quasimonochromatic scalar waves is developed, which describes the propagation of arbitrary quantum states as a boundary-value problem suitable for communication system analysis.

Apodization theory is concerned with the determination of the distribution of light over the exit pupil of an optical system required in order to achieve a suppression of the side lobes of the

Entanglement-assisted capacity of a quantum channel and the reverse Shannon theorem

In the classical analog of entanglement-assisted communication - communication over a discrete memoryless channel (DMC) between parties who share prior random information - one parameter is sufficient, i.e., that in the presence of prior shared random information, all DMCs of equal capacity can simulate one another with unit asymptotic efficiency.
