Anisotropically high entanglement of biphotons generated in spontaneous parametric down conversion
M. V. Fedorov, M. A. Efremov, P. A. Volkov +3
We show that the wave packet of a biphoton generated via spontaneous parametric down conversion is strongly anisotropic. Its anisotropic features manifest themselves very clearly i…
Quantum fluctuations of Coulomb Potential as a Source of Flicker Noise. The Influence of Heat Bath
Kirill A. Kazakov
The power spectrum of finite-temperature quantum electromagnetic fluctuations produced by elementary charge carriers under the influence of external electric field is investigated.…
Dispersion spreading of polarization-entangled states of light and two-photon interference
G. Brida, M. V. Chekhova, M. Genovese +1
We study the interference structure of the second-order intensity correlation function for polarization-entangled two-photon light obtained from type-II collinear frequency-degener…
Quantization of noncommutative completely integrable Hamiltonian systems
G. Giachetta, L. Mangiarotti, G. Sardanashvily
Integrals of motion of a Hamiltonian system need not be commutative. The classical Mishchenko-Fomenko theorem enables one to quantize a noncommutative completely integrable Hamilto…
Dispersion spreading of biphotons in optical fibres and two-photon interference
G. Brida, M. V. Chekhova, M. Genovese +2
We present the first observation of two-photon polarization interference structure in the second-order Glauber's correlation function of two-photon light generated via type-II spon…
Polarization ququarts
Yu. I. Bogdanov, E. V. Moreva, G. A. Maslennikov +3
We discuss the concept of polarization states of four-dimensional quantum systems based on frequency non-degenerate biphoton field. Several quantum tomography protocols were develo…
