In a recent survey, nearly 1 in 3 Americans said they would rather clean a toilet than do a single math problem. Tell someone on the street that you are a physicist, or worse, a mathematician, and you’ll be acknowledged with a “I hated math in school” or “I was never any good at math.” Tell them you are a quantum physicist and you’ll be lucky if you get a response. Chris Ferrie plans to vanquish those doubts and fears by introducing children to quantum physics. But, how young is too young? Enter Quantum Physics for Babies.
Hear from author and quantum theorist Chris Ferrie, IQC and University of Waterloo, Faculty of Mathematics alumnus, about his experience in communicating quantum information science to a larger audience. This general talk is suitable for all audiences.
The international Quantum Key Distribution (QKD) Summer School is a five-day program focused on theoretical and experimental aspects of quantum communication with a focus on quantum cryptography. Established in 2008, QKD occurs every other year and was last held in 2015.
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.
