Modeling Quantum Noise in Nanolasers using Markov Chains

Matias Bundgaard-Nielsen, Gian Luca Lippi, Jesper Mørk

The random nature of spontaneous emission leads to unavoidable fluctuations in a laser's output. This is often included through random Langevin forces in laser rate equations, but…

Entanglement-based clock syntonization for quantum key distribution networks. Demonstration over a 50 km-long link

Yoann Pelet, Grégory Sauder, Sébastien Tanzilli +2

We present the implementation of a time synchronization protocol as part of an experimentally deployed entanglement-based quantum key distribution (QKD) link. The system is deploye…

Two-photon interference at a telecom wavelength for quantum networking

Mathis Cohen, Laurent Labonté, Romain Dalidet +2

The interference between two independent photons stands as a crucial aspect of numerous quantum information protocols and technologies. In this work, we leverage fiber-coupled devi…

Accurate and precise optical phase sensor based on a non-linear quantum Sagnac interferometer

Romain Dalidet, Laurent Labonté, Gregory Sauder +2

Optical phase measurements play a key role in the detection of macroscopic parameters such as position, velocity, and displacement. They also permit to qualify the microscopic prop…

Spikes in Poissonian quantum trajectories

Alan Sherry, Cedric Bernardin, Abhishek Dhar +2

We consider the dynamics of a continuously monitored qubit in the limit of strong measurement rate where the quantum trajectory is described by a stochastic master equation with Po…

Hidden quantum correlations in cavity-based quantum optics

Bakhao Dioum, Virginia D'Auria, Giuseppe Patera

In multimode optical systems, the spectral covariance matrix encodes all the information about quantum correlations between the quadratures of Gaussian states. Recent research has…
