Mean propagation velocity of multiphoton wave-packet states with nonzero Lorentz-invariant mass
S. V. Vintskevich, D. A. Grigoriev
The concept of Lorenz invariant mass and mean propagation velocity have been investigated in detail for various multiphoton wave-packet states of light. Based on photodetection the…
Lorentz-invariant mass and entanglement of biphoton states
S. V. Vintskevich, D. A. Grigoriev, M. V. Fedorov
The concept of the Lorentz-invariant mass of a group of particles is shown to be applicable to biphoton states formed in the process of spontaneous parametric down conversion. The…
Effect of incoherent pump on two-mode entanglement in optical parametric generation
S. V. Vintskevich, D. A. Grigoriev, S. N. Filippov
Pumping a nonlinear crystal by an intense radiation results in the optical parametric generation of photons in two modes (the signal and the idler). The quantized electromagnetic f…
Machine learning non-Markovian quantum dynamics
I. A. Luchnikov, S. V. Vintskevich, D. A. Grigoriev +1
Machine learning methods have proved to be useful for the recognition of patterns in statistical data. The measurement outcomes are intrinsically random in quantum physics, however…
Entanglement of multiphoton polarization Fock states and their superpositions
S. V. Vintskevich, D. A. Grigoriev, N. I. Miklin +1
Density matrices of pure multiphoton Fock polarization states and of arising from them reduced density matrices of mixed states are expressed in similar ways in terms of matrices o…
Temporal interference effects in noncollinear and frequency-nondegenerate spontaneous parametric down-conversion
M. V. Fedorov, A. A. Sysoeva, S. V. Vintskevich +1
We consider regimes of Spontaneous Parametric Down-Conversion both noncollinear and nondegenerate in frequencies. Parameters characterizing degrees of noncollinearity and of nondge…
