Maximal Proper Acceleration and the Quantum-to-Classical Transition
Howard E. Brandt
I first review the physical basis for the universal maximal proper acceleration. Next, I introduce a new formulation for a relativistic scalar quantum field which generalizes the c…
Expanded Quantum Cryptographic Entangling Probe
Howard E. Brandt, John M. Myers
The paper [Howard E. Brandt, "Quantum Cryptographic Entangling Probe," Phys. Rev. A 71, 042312 (2005)] is generalized to include the full range of error rates for the projectively…
Expanded Conclusive Eavesdropping in Quantum Key Distribution
Howard E. Brandt, John M. Myers
The paper [Howard E. Brandt, "Conclusive eavesdropping in quantum key distribution," J. Opt. B: Quantum Semiclass. Opt. 7 (2005)] is generalized to include the full range of error…
Conclusive Entangling Probe
Howard E. Brandt
A design is given for an optimized entangling probe attacking the BB84 (Bennett-Brassard 1984) protocol of quantum key distribution and yielding maximum information to the probe fo…
Quantum Vacuum Heuristics
Howard E. Brandt
Didactic heuristic arguments, based on the quantum mechanics of the vacuum and the structure of spacetime, are reviewed concerning particle creation from the vacuum by an electric…
Optimum Probe Parameters for Entangling Probe in Quantum Key Distribution
Howard E. Brandt
For the four-state protocol of quantum key distribution, optimum sets of probe parameters are calculated for the most general unitary probe in which each individual transmitted pho…
