Multi-Output Quantum Pulse Gate: a High-Dimensional Temporal-Mode Decoder

Autor: L. Serino, J. Gil-Lopez, M. Stefszky, R. Ricken, C. Eigner, B. Brecht, C. Silberhorn

Publikováno v: Frontiers in Optics + Laser Science 2022 (FIO, LS).

We demonstrate a temporal-mode decoder based on a multi-output quantum pulse gate. Measurement tomography on a complete set of five-dimensional mutually unbiased bases confirms single-photon-level operation at telecom wavelengths with an average fide

Sensing with few photons: the power of correlations in lossy SU(1,1) interferometers

Autor: M. Santandrea, K. H. Luo, M. Stefszky, J. Sperling, H. Herrmann, B. Brecht, C. Silberhorn

Publikováno v: Quantum Information and Measurement VI 2021.

This work explores the phase uncertainty of lossy SU(1,1) interferometers in the low gain regime. We show that coincidence measurement can reach the lowest phase uncertainty possible in the system, regardless of the internal losses.

Much progress, both experimentally and theoretically, has recently been made towards optical-frequency-comb generation from continuously pumped second-order nonlinear systems. Here, we present observations towards finding an integrated solution for s
