Entanglement Routing over Networks with Time Multiplexed Repeaters
Emily A Van Milligen, Eliana Jacobson, Ashlesha Patil +3
Quantum networks will be able to service consumers with long-distance entanglement by use of quantum repeaters that generate Bell pairs (or links) with their neighbors, iid with pr…

Fundamental Limits of Covert Communication over Classical-Quantum Channels
Michael S. Bullock, Azadeh Sheikholeslami, Mehrdad Tahmasbi +3
We investigate covert communication over general memoryless classical-quantum channels with fixed finite-size input alphabets. We show that the square root law (SRL) governs covert…

Bayesian quantum phase estimation with fixed photon states
Boyu Zhou, Saikat Guha, Christos N. Gagatsos
We consider a two-mode bosonic state with fixed photon number , whose upper and lower modes pick up a phase and respectively. We compute the optimal Fo…
