Bloch-Messiah reduction for twin beams of light
D. B. Horoshko, L. La Volpe, F. Arzani +3
We study the Bloch-Messiah reduction of parametric downconversion of light in the pulsed regime with a nondegenerate phase matching providing generation of twin beams. We find that…
High-dimensional quantum encoding via photon-subtracted squeezed states
Francesco Arzani, Alessandro Ferraro, Valentina Parigi
We introduce a high-dimensional quantum encoding based on coherent mode-dependent single-photon subtraction from multimode squeezed states. This encoding can be seen as a generaliz…
Random coding for sharing bosonic quantum secrets
Francesco Arzani, Giulia Ferrini, Frédéric Grosshans +1
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…
Violating Bell inequalities with entangled optical frequency combs and multi-pixel homodyne detection
William N. Plick, Francesco Arzani, Nicolas Treps +2
We have theoretically investigated the possibility of using any of several continuous-variable Bell-type inequalities - for which the dichotomic measurements are achieved with coar…
Reconfigurable Optical Quantum Networks Using Multimode Quantum Frequency Combs and Pulse Shaping
Y. Cai, J. Roslund, G. Ferrini +4
Multimode entanglement is quintessential for the design and fabrication of quantum networks, which play a central role in quantum information processing and quantum metrology. Howe…
