Classical and quantum electromagnetic momentum in anisotropic optical waveguides
Denis Kopylov, Manfred Hammer
The guided modes supported by dielectric channel waveguides act as individual carriers of momentum. We show this by proving that the modes satisfy an orthogonality condition which…
Measurement-induced cubic phase state generation
Harsh Kashyap, Denis A. Kopylov, Polina R. Sharapova
The cubic phase state constitutes a nonlinear resource that is essential for universal quantum computing protocols. However, constructing such non-classical states faces many chall…
Bipartite entanglement extracted from multimode squeezed light generated in lossy waveguides
Denis A. Kopylov, Torsten Meier, Polina R. Sharapova
Entangled two-mode Gaussian states constitute an important building block for continuous variable quantum computing and communication protocols. In this work, we theoretically stud…
Multiphoton, multimode state classification for nonlinear optical circuits
Denis A. Kopylov, Christian Offen, Laura Ares +5
We introduce a new classification of multimode states with a fixed number of photons. This classification is based on the factorizability of homogeneous multivariate polynomials an…
Spectral and temporal properties of type-II parametric down-conversion: The impact of losses during state generation
Denis A. Kopylov, Michael Stefszky, Torsten Meier +2
In this paper, we theoretically study spectral and temporal properties of pulsed spontaneous parametric down-conversion (SPDC) generated in lossy waveguides. Our theoretical approa…
