Reconstructing 2D spatial modes for classical and quantum light
Valentin A. Averchenko, Gaetano Frascella, Mahmoud Kalash +2
We propose a method for finding 2D spatial modes of thermal field through a direct measurement of the field intensity and an offline analysis of its spatial fluctuations. Using thi…
Efficient generation of temporally shaped photons using nonlocal spectral filtering
Valentin Averchenko, Denis Sych, Christoph Marquardt +1
We study the generation of single-photon pulses with the tailored temporal shape via nonlocal spectral filtering. A shaped photon is heralded from a time-energy entangled photon pa…
Off-resonant emission of photon pairs in nonlinear optical cavities
Valentin A. Averchenko, Gerhard Schunk, Michael Förtsch +4
Cavity-assisted spontaneous parametric down-conversion (SPDC) and spontaneous four-wave mixing (SFWM) in nonlinear optical materials are practical and versatile methods to generate…
Heralded temporal shaping of single photons enabled by entanglement
Valentin Averchenko, Denis Sych, Gerd Leuchs
We propose a method to produce pure single photons with an arbitrary designed temporal shape in a heralded, lossless and scalable way. As the indispensable resource, the method use…
Shaping a single photon without interacting with it
Denis Sych, Valentin Averchenko, Gerd Leuchs
Complete control over the properties of light up to the level of single photons is an invaluable tool for quantum information science and fundamental studies of light-matter intera…
How subtraction of a single photon affects many quantum modes
Valentin A. Averchenko, Clément Jacquard, Valérian Thiel +2
The subtraction of a single photon from a multimode quantum field is analyzed as the conditional evolution of an open quantum system. We develop a theory describing different subtr…
