Fishing for Eavesdroppers
Paul A. Lopata, Thomas B. Bahder
A method is given to detect the presence of eavesdroppers when a noisy message is sent to a privileged receiver. A proof of the effectiveness if this method is demonstrated, and a…
The effectiveness of quantum operations for eavesdropping on sealed messages
Paul A Lopata, Thomas B Bahder
A quantum protocol is described which enables a user to send sealed messages and that allows for the detection of active eavesdroppers. We examine a class of eavesdropping strategi…
Phase Sensitivity of a Mach-Zehnder Quantum Sensor
Thomas B. Bahder, Paul A. Lopata
We investigate the dependence of the fidelity of a Mach-Zehnder quantum interferometer on the prior information about the phase, for Fock state input and for maximally entangled (N…
Sending Sensitive Messages in Quantum Packages
Paul A. Lopata, Thomas B. Bahder
A communication protocol is introduced that allows the receiver of a message to place an a posteriori bound on the amount of information that an eavesdropper could have obtained du…
Fidelity of Quantum Interferometers
Thomas B. Bahder, Paul A. Lopata
For a generic interferometer, the conditional probability density distribution, , for the phase given measurement outcome , will generally have multiple peaks. There…
Translation of Quantum Texts
Randall Espinoza, Tom Imbo, Paul Lopata
In the companion to this paper, we described a generalization of the deterministic quantum cloning process, called enscription, which utilizes entanglement in order to achieve the…
