Entangled: The series

Hear Raymond Laflamme, founding director of the Institute for Quantum Computing and John von Neumann Chair in Quantum Information and Edwin Outwater, Music Director Laureate of the Kitchener-Waterloo Symphony, as they have a conversation about the making of Does God Play Dice (Quantum Etude).

Radio host Mike Farwell will moderate this conversation about their collaboration that integrated quantum physics and music to create a surprisingly random performance piece. You’ll even have the to watch highlights of the April 20 performance.

I will report on dynamical magnetic susceptibility measurements of
both bulk and thin film samples of the spin glass Copper Manganese.
By studying the Thermoremanent Magnetization (TRM) of multi-layer thin
films of various thicknesses, we are able to show the maximum energy
barrier encountered during correlated spin flip transitions is cut off
by the thickness of the film and is independent of temperature. The
distribution of energy barriers is shown to follow from a hierarchical

Evan Meyer-Scott, Universität Paderborn 

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.

Active beam splitting attack applied to coherent-state based QKD protocols

Dmitry Kronberg, Lomonosov Moscow State University


We consider a new type of attack on a coherent state-based quantum key distribution protocols (like coherent one-way (COW) or differential phase-shift (DPS) protocol). The main idea of the attack consists in measuring individually the intercepted states and sending the rest of them unchanged. In some cases, this attack can be considered as a generalization of well-known beam-splitting attack and unambiguous state discrimination attack.
