Three-dimensional Quantum Polarization Tomography of Macroscopic Bell States
Bhaskar Kanseri, Timur Iskhakov, Ivan Agafonov +2
The polarization properties of macroscopic Bell states are characterized using three-dimensional quantum polarization tomography. This method utilizes three-dimensional inverse Rad…
Polarization-Entangled Light Pulses of 10^5 Photons
Timur Sh. Iskhakov, Ivan N. Agafonov, Maria V. Chekhova +1
We experimentally demonstrate polarization entanglement for squeezed vacuum pulses containing more than 10^5 photons. We also study photon-number entanglement by calculating the Sc…
Filtering of the absolute value of photon-number difference for two-mode macroscopic quantum superpositions
Magdalena Stobińska, Falk Töppel, Pavel Sekatski +5
We discuss a device capable of filtering out two-mode states of light with mode populations differing by more than a certain threshold, while not revealing which mode is more popul…
Macroscopic Bell States and the Higher-Order Degree of Polarization
Timur Sh. Iskhakov, Ivan N. Agafonov, Maria V. Chekhova +2
We study polarization properties of the macroscopic analogues of two-photon Bell states. The effect of hidden polarization, i.e., polarization in the second (and higher) orders in…
Systematic analysis of SNR in bipartite Ghost Imaging with classical and quantum light
G. Brida, M. V. Chekhova, G. A. Fornaro +3
We present a complete and exhaustive theory of signal-to-noise-ratio in bipartite ghost imaging with classical (thermal) and quantum (twin beams) light. The theory is compared with…
