A quantum analog of Huffman coding
Samuel L. Braunstein, Christopher A. Fuchs, Daniel Gottesman +1
We analyze a generalization of Huffman coding to the quantum case. In particular, we notice various difficulties in using instantaneous codes for quantum communication. Nevertheles…
Efficient Quantum Key Distribution
M. Ardehali, H. F. Chau, Hoi-Kwong Lo
We devise a simple modification that essentially doubles the efficiency of a well-known quantum key distribution scheme proposed by Bennett and Brassard (BB84). Our scheme assigns…
Unconditional Security Of Quantum Key Distribution Over Arbitrarily Long Distances
Hoi-Kwong Lo, H. F. Chau
Quantum key distribution is widely thought to offer unconditional security in communication between two users. Unfortunately, a widely accepted proof of its security in the presenc…
