A macroscopic quantum state analysed particle by particle
Federica A. Beduini, Joanna A. Zielinska, Vito G. Lucivero +2
Explaining how microscopic entities collectively produce macroscopic phenomena is a fundamental goal of many-body physics. Theory predicts that large-scale entanglement is responsi…
Long-term laser frequency stabilization using fiber interferometers
Jia Kong, Vito Giovanni Lucivero, Ricardo Jimenez-Martinez +1
We report long-term laser frequency stabilization using only the target laser and a pair of 5 m fiber interferometers, one as a frequency reference and the second as a sensitive th…
Interferometric measurement of the biphoton wave function
Federica A. Beduini, Joanna A. Zielińska, Vito G. Lucivero +2
Interference between an unknown two-photon state (a "biphoton") and the two-photon component of a reference state gives a phase-sensitive arrival-time distribution containing full…
Atomic filtering for hybrid continuous-variable/discrete-variable quantum optics
Joanna A. Zielińska, Federica A. Beduini, Vito Giovanni Lucivero +1
We demonstrate atomic filtering of frequency-degenerate photon pairs from a sub-threshold optical parametric oscillator (OPO). The filter, a modified Faraday anomalous dispersion o…
Shot-noise-limited magnetometer with sub-pT sensitivity at room temperature
Vito Giovanni Lucivero, Pawel Anielski, Wojciech Gawlik +1
We report a photon shot-noise-limited (SNL) optical magnetometer based on amplitude modulated optical rotation using a room-temperature Rb vapor in a cell with anti-relaxati…
Optimal Signal Recovery for Pulsed Balanced Detection
Yannick A. de Icaza Astiz, Vito Giovanni Lucivero, R. de J. León-Montiel +1
We demonstrate a new tool for filtering technical and electronic noises from pulses of light, especially relevant for signal processing methods in quantum optics experiments as a m…
