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.

As we know, spacetime is not flat at the cosmological scale. In order to describe spacetime, in General Relativity theory (GR), we need a continuous and differentiable manifold and a formal way to account for the continuous distortion of the metrics. The main point is that changing coordinate systems should not affect physics laws (General Covariance). However at the Planck length, matter is not continuous and obeys Quantum Theory (QT).

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.

The 5th European Telecommunications Standards Institute (ETSI)/Institute for Quantum Computing (IQC) Workshop will take place in London (UK) on 13 – 15 September 2017.

It will start with a special Executive Track on 13 September and will be followed by an in depth technical track on 14-15 September 2017, on which ETSI is currently calling for presentations and poster session.
