In distributed functional monitoring (DFM), N players located at different sites; each observes a stream of items and communicates with one coordinator, whose goal is to compute a function of the union of the streams. In threshold monitoring, a special case of DFM, the coordinator wants to know whether f(v(t))>T\documentclass[12pt]{minimal} \usepac...

We consider a protocol for sharing quantum states using continuous variable systems. Specifically we introduce an encoding procedure where bosonic modes in arbitrary secret states are mixed with several ancillary squeezed modes through a passive interferometer. We derive simple conditions on the interferometer for this encoding to define a secret s...

The future of integrated quantum photonics relies heavily on the ability to engineer refined methods for preparing the quantum states needed to implement various quantum protocols. An important example of such states is quantum-correlated photon pairs, which can be efficiently generated using spontaneous nonlinear processes in integrated microring-...
