Comment on ``Consistent Sets Yield Contrary Inferences in Quantum Theory''
Robert B. Griffiths, James B. Hartle
In a recent paper Kent has pointed out that in consistent histories quantum theory it is possible, given initial and final states, to construct two different consistent families of…
Choice of Consistent Family, and Quantum Incompatibility
Robert B. Griffiths
In consistent history quantum theory, a description of the time development of a quantum system requires choosing a framework or consistent family, and then calculating probabiliti…
The Exact Ground State of the Frenkel-Kontorova Model with Repeated Parabolic Potential: II. Numerical Treatment
T. Scheidsteger, H. Urbschat, R. B. Griffiths +1
A procedure is described for efficiently finding the ground state energy and configuration for a Frenkel-Kontorova model in a periodic potential, consisting of N parabolic segments…
The Exact Ground State of the Frenkel-Kontorova Model with Repeated Parabolic Potential: I. Basic Results
R. B. Griffiths, H. J. Schellnhuber, H. Urbschat
The problem of finding the exact energies and configurations for the Frenkel-Kontorova model consisting of particles in one dimension connected to their nearest-neighbors by spring…
Optimal Eavesdropping in Quantum Cryptography. II. Quantum Circuit
Robert B. Griffiths, Chi-Sheng Niu
It is shown that the optimum strategy of the eavesdropper, as described in the preceding paper, can be expressed in terms of a quantum circuit in a way which makes it obvious why c…
Optimal Eavesdropping in Quantum Cryptography. I
Christopher A. Fuchs, Nicolas Gisin, Robert B. Griffiths +2
We consider the Bennett-Brassard cryptographic scheme, which uses two conjugate quantum bases. An eavesdropper who attempts to obtain information on qubits sent in one of the bases…
