Nonlocal Dispersion Cancellation using Entangled Photons
So-Young Baek, Young-Wook Cho, Yoon-Ho Kim
A pair of optical pulses traveling through two dispersive media will become broadened and, as a result, the degree of coincidence between the optical pulses will be reduced. For a…
Minimum Disturbance Measurement without Post-Selection
So-Young Baek, Yong Wook Cheong, Yoon-Ho Kim
We propose and demonstrate a linear optical device which deterministically performs optimal quantum measurement or minimum disturbance measurement on a single-photon polarization q…
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…
