Phase Sensitivity of Spectrally Multimode SU(1,1) Interferometers with Waveguide based Optical Parametric Amplifier
Sonu Jana, Swagatam Bag, Fabien Bretenaker +2
We present a comprehensive framework for evaluating the phase sensitivity of spectrally multimode SU(1,1) interferometers probed with a coherent-vacuum input, under both number and…
Sensitivity Evaluation of SU(1,1) Interferometers with Arbitrary Input Probe State and Homodyne Detections
Sonu Jana, Dhruv Baheti, Paul Grossiord +3
We provide a general theoretical derivation of the phase sensitivity achieved by SU(1,1) interferometers under homodyne detection. The general expressions obtained accommodate arbi…
Generation of frequency entanglement with an effective quantum dot-waveguide two-photon quadratic interaction
Mohamed Meguebel, Maxime Federico, Simone Felicetti +2
Light-matter interactions with quantum dots have been extensively studied to harness key quantum properties of photons, such as indistinguishability and entanglement. In this theor…
Continuous-variable spatio-spectral quantum networks in nonlinear photonic lattices
Natalia Costas, Nadia Belabas, David Barral
Multiplexing information in different degrees of freedom and use of integrated and fiber-optic components are natural solutions to the scalability bottleneck in optical quantum com…
Multi-dimensional frequency-bin entanglement-based quantum key distribution network
George Claudiu Crisan, Antoine Henry, Dario Alessandro Fioretto +7
Quantum networks enhance quantum communication schemes and link multiple users over large areas. Harnessing high dimensional quantum states - i.e. qu-d-its - allows for a denser tr…
