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, IQC and University of ݮƵ, Faculty of Mathematicsalumnus,about his experience in communicating quantum information science to a larger audience. This general talk is suitable for all audiences.
The Quantum Key Distribution (QKD) Summer School, hosted by IQC, equips graduate students and young postdoctoral fellows with a strong foundation in quantum communication, particularly quantum cryptography.
An essential prerequisite for quantum information processing is precise coherent control ofthe dynamics of quantum systems or quantum bits (qubits). Most of the control sequencesimplemented in quantum experiments are developed and designed based on the assumption ofhaving 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 unambiguousquantum state discrimination (USD) is developed. We consider aprepare-and-measure protocol, where two non-orthogonal quantum states canbe prepared, and a measurement device aims at unambiguously discriminatingbetween 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.
