Gain of squeezing via photon subtractions
Mikhail S. Podoshvedov, Sergey A. Podoshvedov, Sergei P. Kulik
We develop a method for generating a more squeezed than single-mode squeezed vacuum (SMSV) state by subtracting 2,4,6 photons from it. In general, the more photons are subtracted,…
Preparation and characterization of arbitrary states of four-dimensional qudits based on biphotons
So-Young Baek, Stanislav S. Straupe, Alexander P. Shurupov +2
We report interferometric schemes to prepare arbitrary states of four-dimensional qudits (ququarts) based on biphoton states of ultrafast-pumped frequency-nondegenerate spontaneous…
Identifying entanglement using quantum "ghost" interference and imaging
Milena D'Angelo, Yoon-Ho Kim, Sergei P. Kulik +1
We report a quantum interference and imaging experiment which quantitatively demonstrates that Einstein-Podolsky-Rosen (EPR) type entangled two-photon states exhibit both momentum-…
