Quantum Lithography in Macroscopic Observations
De-Zhong Cao, Kaige Wang
We study the generalized Young's double-slit interference for the beam produced in the spontaneously parametric down-conversion (SPDC). We find that the sub-wavelength lithography…
Even and odd q-deformed charge coherent states and their nonclassical properties
X. -M. Liu, C. Quesne
Even and odd q-deformed charge coherent states are constructed, their (over)completeness proved and their generation explored. A -algebra realization of the SU(1,1) generato…
Two Photon Anti-Coalescence Interference: the Signature of Two Photon Entanglement
Kaige Wang, Shiyao Zhu
We study a general theory on the interference of two-photon wavepacket in a beam splitter. We find that the symmetry of two-photon spectrum plays an important role in the manners o…
Coalescence and Anti-Coalescence Interference of Two-Photon Wavepacket in a Beam Splitter
Kaige Wang
We study a general theory on the interference of two-photon wavepacket in a beam splitter (BS). We find that the perfect coalescence interference requires a symmetric spectrum of t…
