Optimal Quantum Phase Estimation
U. Dorner, R. Demkowicz-Dobrzanski, B. J. Smith +4
By using a systematic optimization approach we determine quantum states of light with definite photon number leading to the best possible precision in optical two mode interferomet…

Entanglement Enhances Security in Secret Sharing
Rafal Demkowicz-Dobrzanski, Aditi Sen De, Ujjwal Sen +1
We analyze tolerable quantum bit error rates in secret sharing protocols, and show that using entangled encoding states is advantageous in the case when the eavesdropping attacks a…
