Nonlinear quantum noise polarization in macroscopic nonlinear QED
Arman Kashef, Stefan Scheel, Marco Ornigotti
We construct a quantum theory of light in nonlinearly responding materials with dispersion and absorption and, in particular, show the emergence of non-Gaussian noise associated wi…
Path integral quantization of the electromagnetic field in nonlinear dielectric materials
Arman Kashef, Oscar Perearnau Herrero, Alexander Szameit +2
We construct a quantum theory of light in nonlinear dielectric media with dispersion and absorption. We employ a mesoscopic model for the light-matter interaction that include a fo…
Observation of the quantum Gouy phase
Markus Hiekkamäki, Rafael F. Barros, Marco Ornigotti +1
Controlling the evolution of a photonic quantum states is crucial for most quantum information processing and metrology tasks. Because of its importance, many mechanisms of quantum…
Path Integrals: From Quantum Mechanics to Photonics
Charles W. Robson, Yaraslau Tamashevich, Tapio T. Rantala +1
The path integral formulation of quantum mechanics, i.e., the idea that the evolution of a quantum system is determined as a sum over all the possible trajectories that would take…
Observation of PT-symmetric quantum interference
Friederike U. J. Klauck, Lucas Teuber, Marco Ornigotti +3
Parity-Time (PT) symmetric quantum mechanics is a complex extension of conventional Hermitian quantum mechanics in which physical observables possess a real eigenvalue spectrum. Ho…
A path integral description of quantum nonlinear optics in arbitrary media
Mosbah Difallah, Alexander Szameit, Marco Ornigotti
We present a method, based on Feynman path integrals, to describe the propagation and properties of the quantised electromagnetic field in an arbitrary, nonlinear medium. We provid…
Demonstration of local teleportation using classical entanglement
Diego Guzman-Silva, Robert Brüning, Felix Zimmermann +8
Teleportation is the most widely discussed application of the basic principles of quantum mechanics. Fundamentally, this process describes the transmission of information, which in…
From waves to bullets: testing Feynman's idea on the two slit experiment
Marco Ornigotti, Andrea Aiello
We test the validity of Feynman's idea that a two-slit experiment performed with classical objects (bullets) does not produce observable interference fringes on the detection scree…
Classically entangled optical beams for high-speed kinematic sensing
Stefan Berg-Johansen, Falk Töppel, Birgit Stiller +6
Tracking the kinematics of fast-moving objects is an important diagnostic tool for science and engineering. Existing optical methods include high-speed CCD/CMOS imaging, streak cam…
Visualization of Coherent Destruction of Tunneling in an Optical Double Well System
G. Della Valle, M. Ornigotti, E. Cianci +3
We report on a direct visualization of coherent destruction of tunneling (CDT) of light waves in a double well system which provides an optical analog of quantum CDT as originally…
