Loss-independent time-delay estimation via Hong-Ou-Mandel photon bunching detection
Julián Defant, Agustina G. Magnoni, Miguel A. Larotonda +1
In this work we study the application of two-photon correlated quantum states for high-precision time estimation. To achieve this, photon pairs were fed into a Hong-Ou-Mandel polar…
Unraveling quantum phase estimation: exploring the impact of multi-photon interference on the quantum Fisher information
Annameng Ma, Agustina G. Magnoni, Miguel A. Larotonda +1
Quantum interference is known to become extinct with distinguishing information, as illustrated by the ubiquitous double-slit experiment or the two-photon HOM effect. In the former…
Towards a fiber-optic temporally multiplexed single photon source
Agustina G. Magnoni, Laura T. Knoll, Lina Wölcken +3
We demonstrate the feasibility of implementing a photon source with sub-Poissonian emission statistics through temporal multiplexing of a continuous wave heralded photon source in…
Simultaneous quantum estimation of phase and indistinguishability in a two photon interferometer
Laura T. Knoll, Gustavo M. Bosyk
With the rapid development of quantum technologies in recent years, the need for high sensitivity measuring techniques has become a key issue. In particular, optical sensors based…
Mode structure reconstruction by detected and undetected light
Laura T. Knoll, Giulia Petrini, Fabrizio Piacentini +5
We introduce a novel technique for the reconstruction of multimode optical fields, based on simultaneously exploiting both the generalized Glauber's -order correlation func…

We propose and experimentally demonstrate a general method allowing us to unravel microscopic noise events that affect a continuous quantum variable. Such unraveling is achieved by…
Emergence of Constructor-based Irreversibility in Quantum Systems: Theory and Experiment
Chiara Marletto, Vlatko Vedral, Laura Knoll +7
The issue of irreversibility in a universe with time-reversal-symmetric laws is a central problem in physics. % , and, in particular, to statistical mechanics, information theory a…
Scheme for sub-shot-noise transmission measurement using a time multiplexed single-photon source
Agustina G. Magnoni, Laura T. Knoll, Miguel A. Larotonda
A promising result from optical quantum metrology is the ability to achieve sub-shot-noise performance in transmission or absorption measurements. This is due to the significantly…

Laura T. Knoll, Gustavo M. Bosyk, Ignacio H. López Grande +1
We report a theoretical and experimental study on the role of indistinguishability in the estimation of an interferometric phase. In particular, we show that the quantum Fisher inf…
Performance of a temporally multiplexed single-photon source with imperfect devices
Agustina G. Magnoni, Ignacio H. López Grande, Laura T. Knoll +1
Scalable photonic quantum technologies require highly efficient sources of single photons on demand. Although much progress has been done in the field within the last decade, the r…
Challenging local realism with human choices
The BIG Bell Test Collaboration, C. Abellán, A. Acín +105
A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…
Photonic quantum simulator for unbiased phase covariant cloning
Laura T. Knoll, Ignacio H. López Grande, Miguel A. Larotonda
We present the results of a linear optics photonic implementation of a quantum circuit that simulates a phase covariant cloner, by using two different degrees of freedom of a singl…
Entanglement breaking channels and entanglement sudden death
Laura T. Knoll, Christian T. Schmiegelow, Osvaldo Jiménez Farías +2
The occurrence of entanglement sudden death in the evolution of a bipartite system depends on both the initial state and the channel responsible for the evolution. An extreme case…
