Quantum cryptography: Public key distribution and coin tossing
A protocol for coin-tossing by exchange of quantum messages is presented, which is secure against traditional kinds of cheating, even by an opponent with unlimited computing power, but ironically can be subverted by use of a still subtler quantum phenomenon, the Einstein-Podolsky-Rosen paradox.

Logical reversibility of computation
This result makes plausible the existence of thermodynamically reversible computers which could perform useful computations at useful speed while dissipating considerably less than kT of energy per logical step. Expand
Efficient estimation of free energy differences from Monte Carlo data
Abstract Near-optimal strategies are developed for estimating the free energy difference between two canonical ensembles, given a Metropolis-type Monte Carlo program for sampling each one. TheExpand
The thermodynamics of computation—a review
Computers may be thought of as engines for transforming free energy into waste heat and mathematical work. Existing electronic computers dissipate energy vastly in excess of the mean thermalExpand
Experimental Quantum Cryptography
Initial results from an apparatus and protocol designed to implement quantum public key distribution are described, by which two users exchange a random quantum transmission, consisting of very faint flashes of polarized light, which remains secure against an adversary with unlimited computing power.

Strengths and Weaknesses of Quantum Computing
It is proved that relative to an oracle chosen uniformly at random with probability 1 the class $\NP$ cannot be solved on a quantum Turing machine (QTM) in time $o(2^{n/2})$. Expand
Relative to a Random Oracle A, PA != NPA != co-NPA with Probability 1
Let A be a language chosen randomly by tossing a fair coin for each string x to determine whether x belongs to A, and${\bf NP}^A is shown, with probability 1, to contain a-immune set, i.e., a set having no infinite subset in ${\bf P]^A $. Expand
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.

Generalized privacy amplification
This paper provides a general treatment of privacy amplification by public discussion, a concept introduced by Bennett, Brassard and Robert (1988) for a special scenario. The results haveExpand
Logical depth and physical complexity
Some mathematical and natural objects (a random sequence, a sequence of zeros, a perfect crystal, a gas) are intuitively trivial, while others (e.g. the human body, the digits of π) contain internalExpand
