18:00 → 18:20 A time-multiplexing approach for Quantum State Discrimination

The need of discriminating between different quantum states is a fundamental issue in Quantum Information and Communication. The actual realization of generally optimal strategies for this task is often limited by the need of supplemental resources and very complex receivers. We develop a novel approach to multi-state quantum discrimination, relying on the dynamical features of a network-like receiver. This strategy exploits the arrival time degree of freedom as an encoding variable, achieving optimal results, without the need for supplemental systems or devices.

18:30 → 18:50 Bio-hybrid microshuttles controlled by light patterns

Design and fabrication of efficient and self-powered microrobots are very active research fields. A fascinating strategy to provide propulsion to artificial microsystems is by using biological microswimmers. Bacteria like Escherichia coli swim by rotating helical flagella that are actuated by a unique biological rotary motor, a dream for modern nanotechnology. Many strategies have been proposed for embedding bacteria into artificial microstructures but very often, although a net movement can be obtained, displacements are stochastic and hard to reproduce. We use 3D direct laser writing to build artificial microstructures that guide the spontaneous assembly of genetically modified bacteria into precise and highly reproducible configurations leading to biohybrid micro-machines with efficient and controllable propulsion through light patterns.
