Polarisation-resolved identification of spontaneous four-wave mixing processes in a multimode fused tapered fibre coupler
Jefferson Flórez, Chams Baker, Benjamin J. Sussman +3
Integrated quantum photonics benefits from photon-pair sources that generate photons directly in waveguides, where they can be efficiently collected, routed, and manipulated. Here,…
Pump depletion in parametric down-conversion with low pump energies
Jefferson Flórez, Jeff S. Lundeen, Maria V. Chekhova
We report the efficient generation of high-gain parametric down-conversion, including pump depletion, with pump powers as low as 100 W (energies ~J/pulse) and conversion…
Controlling Non-Markovian Dynamics Using a Light-based Structured Environment
Daniel F. Urrego, Jefferson Flórez, Jiří Svozilík +2
We present the experimental control of Non-Markovian dynamics of open quantum systems simulated with photonic entities. The polarization of light is used as the system, whereas the…
The phase sensitivity of a fully quantum three-mode nonlinear interferometer
Jefferson Flórez, Enno Giese, Davor Curic +3
We study a nonlinear interferometer consisting of two consecutive parametric amplifiers, where all three optical fields (pump, signal and idler) are treated quantum mechanically, a…
Projecting onto any two-photon polarization state using linear optics
G. S. Thekkadath, L. Giner, X. Ma +2
Projectors are a simple but powerful tool for manipulating and probing quantum systems. For instance, projecting two-qubit systems onto maximally entangled states can enable quantu…
An experimental investigation of measurement-induced disturbance and time symmetry in quantum physics
Davor Curic, Magdalena C. Richardson, Guillaume S. Thekkadath +3
Unlike regular time evolution governed by the Schrödinger equation, standard quantum measurement appears to violate time-reversal symmetry. Measurement creates random disturbances…
Correlation control for pure and efficiently generated heralded single photons
Jefferson Flórez, Omar Calderón, Clara I. Osorio +1
We present a detailed study on the properties of single photons generated by spontaneous parametric down conversion (SPDC) when both the spectral and spatial degrees of freedom are…
Near field enhancement due to the optical response of small nanoparticles
Mario Zapata-Herrera, Jefferson Flórez, Angela Camacho +1
In this work we study the strong confinement effects on the electromagnetic response of metallic nanoparticles. We calculate the field enhancement factor for nanospheres of various…
