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…
