Absolute calibration of photodetectors: photocurrent multiplication versus photocurrent subtraction
I. N. Agafonov, M. V. Chekhova, T. Sh. Iskhakov +3
We report testing of the new absolute method of photodetectors calibration based on the difference-signal measurement for two-mode squeezed vacuum by comparison with the traditiona…
Macroscopic Pure State of Light Free of Polarization Noise
Timur Sh. Iskhakov, Maria V. Chekhova, Georgy O. Rytikov +1
The preparation of completely non-polarized light is seemingly easy: an everyday example is sunlight. The task is much more difficult if light has to be in a pure quantum state, as…
Comparative Test of Two Methods of Quantum Efficiency Absolute Measurement Based on Squeezed Vacuum Direct Detection
I. N. Agafonov, M. V. Chekhova, T. Sh. Iskhakov +3
We realize and test in experiment a method recently proposed for measuring absolute quantum efficiency of analog photodetectors. Similarly to the traditional (Klyshko) method of ab…
