Deterministic quantum correlation in an interferometric scheme
Byoung S. Ham
Over the last several decades, entangled photon pairs generated from \c{hi}^((2)) nonlinear optical materials via spontaneous parametric down conversion processes have been intensi…
Observations of on-demand quantum correlation using Poisson-distributed photon pairs
Sangbae Kim, Byoung S. Ham
Complementarity or wave-particle duality has been the basis of quantum mechanics over the last century. Since the Hanbury Brown and Twiss experiments in 1956, the particle nature o…
Phase noise-immune unconditionally secured classical key distribution using doubly coupled Mach-Zehnder interferometer
Byoung S. Ham
Recently, new physics for unconditional security in a classical key distribution (USCKD) in a frame of a double Mach-Zehnder interferometer has been proposed and demonstrated as a…
Experimental demonstrations of unconditional security in a purely classical regime
Byoung S. Ham
So far, unconditional security in key distribution processes has been confined to quantum key distribution (QKD) protocols based on the no-cloning theorem of nonorthogonal bases. R…
Analysis of nonclasscial features in a coupled macroscopic binary system
Byoung S. Ham
Nonclassical phenomena of quantum mechanics such as anticorrelation and photonic de Broglie waves (PBWs) have been recently understood as a special case of coherence optics with a…
Observations of coherence de Broglie waves
Byoung S. Ham
Photonic de Broglie waves (PBWs) via two-mode entangled photon pair interactions on a beam splitter show a pure quantum feature which cannot be obtained by classical means1-4. Alth…
