Measurement of the total energy of an isolated system by an internal observer
S. Massar, S. Popescu
We consider the situation in which an observer internal to an isolated system wants to measure the total energy of the isolated system (this includes his own energy, that of the me…
Quantum entanglement can be simulated without communication
N. J. Cerf, N. Gisin, S. Massar +1
It has recently been shown that all causal correlations between two parties which output each one bit, a and b, when receiving each one bit, x and y, can be expressed as convex com…
Quantum Gloves
D. Collins, L. Diosi, N. Gisin +2
The slogan "information is physical" has been so successful that it led to some excess. Classical and quantum information can be thought of independently of any physical implementa…
Security of Quantum Bit-String Generation
Jonathan Barrett, Serge Massar
We consider the cryptographic task of bit-string generation. This is a generalisation of coin tossing in which two mistrustful parties wish to generate a string of random bits such…
Error Filtration and Entanglement Purification for Quantum Communication
N. Gisin, N. Linden, S. Massar +1
The key realisation which lead to the emergence of the new field of quantum information processing is that quantum mechanics, the theory that describes microscopic particles, allow…
Lower bound on the number of Toffoli gates in a classical reversible circuit through quantum information concepts
Sandu Popescu, Berry Groisman, Serge Massar
The question of finding a lower bound on the number of Toffoli gates in a classical reversible circuit is addressed. A method based on quantum information concepts is proposed. The…
