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…
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…
Sensing microscopic noise events by frequent quantum measurements
Salvatore Virzì, Laura T. Knoll, Alessio Avella +8
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…
Testing randomness of series generated in Bell's experiment
Myriam Nonaka, Mónica Agüero, Marcelo Kovalsky +1
The generation of series of random numbers is an important and difficult problem. Even the very definition of random is difficult. Appropriate measurements on entangled states have…
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…
Role of indistinguishability in interferometric phase estimation
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…
Implementation of a hybrid scheme for coherent plug-and-play quantum key distribution
Ignacio H. López Grande, Miguel A. Larotonda
We experimentally demonstrate a hybrid configuration for Quantum Key Distribution, that combines the simplicity of Distributed Phase Reference protocols with the self-referencing f…
Kolmogorov complexity of sequences of random numbers generated in Bell's experiments
Marcelo G. Kovalsky, Alejandro A. Hnilo, Mónica B. Agüero
Quantum systems are the ultimate touchstone for the production of random sequences of numbers. Spatially spread entangled systems allow the generation of identical random sequences…
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…
Distinguishing computable mixtures of quantum states
Ignacio H. López Grande, Gabriel Senno, Gonzalo de la Torre +4
In this article we extend results from our previous work [Bendersky, de la Torre, Senno, Figueira and Acín, Phys. Rev. Lett. 116, 230406 (2016)] by providing a protocol to distingu…
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…
Eberhardt's inequality and recent loophole-free experiments
Alejandro Hnilo
Recent experiments using innovative optical detectors and techniques have strongly increased the capacity of testing the violation of the Bell's inequalities in the Nature. Most of…
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…
Noisy quantum teleportation: An experimental study on the influence of local environments
Laura T. Knoll, Christian T. Schmiegelow, Miguel A. Larotonda
We report experimental results on the action of selected local environments on the fidelity of the quantum teleportation protocol, taking into account non-ideal, realistic entangle…
