A proposal for founding mistrustful quantum cryptography on coin tossing
ly, the basic idea is this. A and B identify some suitable graded class C = ⊕n≥0Cn of mathematical objects with the property that there is some increasing function f(n) such that the members of Cn can be identified by f(n) bits. They also identify a classD = ⊕n≥0Dn of mathematical objects, with a relation → defining a subset of D × C: we say d ∈ D is associated to c ∈ C if d → c. Before impleme...
متن کاملExperimental quantum coin tossing.
In this Letter we present the first implementation of a quantum coin-tossing protocol. This protocol belongs to a class of "two-party" cryptographic problems, where the communication partners distrust each other. As with a number of such two-party protocols, the best implementation of the quantum coin tossing requires qutrits, resulting in a higher security than using qubits. In this way, we ha...
متن کاملRelativistic quantum coin tossing
A relativistic quantum information exchange protocol is proposed allowing two distant users to realize “coin tossing” procedure. The protocol is based on the point that in relativistic quantum theory reliable distinguishing between the two orthogonal states generally requires a finite time depending on the structure of these states. PACS numbers: 03.67.-a, 03.65.Bz, 42.50Dv The coin tossing pro...

متن کاملQuantum Bit Commitment and Coin Tossing Protocols
In the late 1960’s a physicist, Stephen Wiesner, had the idea that the uncertainty principle could be used for cryptography (though he published his result much later [Wie83]). One of his ideas was that it would be possible to use a stream of polarized photons to transmit two messages in a way that would make only one of them readable at the receiver’s choosing. This notion, which he called “mu...
