Colloquium featuring Heejeong Jeong -��Hong Kong University of Science and Technology

Optical precursors are transient electromagnetic wave packets propagating precisely at the speed of light in vacuum through a dispersive and absorptive dielectric. Even though its existence was conjectured by Sommerfeld and Brillouin 100 years ago, the detection seemed to be impossible due to its exceedingly small amplitude and femtosecond time scale in ordinary linear dispersive media.��

An essential prerequisite for quantum information processing is precise coherent control of��the dynamics of quantum systems or quantum bits (qubits). Most of the control sequences��implemented in quantum experiments are developed and designed based on the assumption of��having ideal (closed) quantum coherent systems.

Recent rapid advancements in nanofabrication technologies have widened the realm of possibilities in nanophotonics, nonlinear and sub-wavelength optics. Realizing nonlinear optics in subwavelength scale paves the way for low cost integrated photonics. Ultra-high-Q photonic crystal nanocavities and nanostructured materials are examples of such structures. Those structures offer very small mode volume guaranteeing highly enhanced field intensity.

An approach to quantum random number generation based on unambiguous��quantum state discrimination (USD) is developed. We consider a��prepare-and-measure protocol, where two non-orthogonal quantum states can��be prepared, and a measurement device aims at unambiguously discriminating��between them.
