Efficient quantum memory in naturally trapped Rare-Earth ions

Mahmood Sabooni, IQC

The ability to map, store quantum states of light (e. g. single photon) to matter and later retrieve is one of the important building blocks of quantum information processing. Such a device is called a quantum memory for light.

The Women in Physics Canada (WIPC) conference, hosted by the University of Waterloo, Faculty of Science, Department of Physics & Astronomy and the Institute for Quantum Computing, will bring together early career scientists to present their research and hear plenary talks from leaders in physics.

We welcome attendance by people of all genders.

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.

I will present a realization of a great photon pair source based on parametric down-conversion, and discuss a not-so-great limit to the performance of photon pair sources in general. The former is a fully fiber-coupled waveguide pair source with 46% raw heralding efficiency, and no optical alignment required. The latter restricts the achievable heralding efficiency, when spectrally filtering the photons to increase the purity.
