Toward Photon-Efficient Key Distribution over Optical Channels
Yuval Kochman, Ligong Wang, Gregory W. Wornell
This work considers the distribution of a secret key over an optical (bosonic) channel in the regime of high photon efficiency, i.e., when the number of secret key bits generated p…
Compression in the Space of Permutations
Da Wang, Arya Mazumdar, Gregory Wornell
We investigate lossy compression (source coding) of data in the form of permutations. This problem has direct applications in the storage of ordinal data or rankings, and in the an…
Throughput-Smoothness Trade-offs in Multicasting of an Ordered Packet Stream
Gauri Joshi, Yuval Kochman, Gregory Wornell
An increasing number of streaming applications need packets to be strictly in-order at the receiver. This paper provides a framework for analyzing in-order packet delivery in such…
The Effect of Block-wise Feedback on the Throughput-Delay Trade-off in Streaming
Gauri Joshi, Yuval Kochman, Gregory Wornell
Unlike traditional file transfer where only total delay matters, streaming applications impose delay constraints on each packet and require them to be in order. To achieve fast in-…
A refined analysis of the Poisson channel in the high-photon-efficiency regime
Ligong Wang, Gregory W. Wornell
We study the discrete-time Poisson channel under the constraint that its average input power (in photons per channel use) must not exceed some constant E. We consider the wideband,…
