The most awaited "Bar du Gap" is back September 28th, and we think you should not miss it! The theme for this year is "EXOTIC" so you have no excuse to arrive without a beautiful costume ;) Your creativity may even pay because this year there will be a "Best Costume Award".

Stefan Wolf de l’Université de Lugano, Pinchat, Seminar room, 4:15pm Landauer's principle claims that "Information is Physical." A flavor of its conceptual antipode, Wheeler's "It from Bit," is the Church/Turing thesis: All natural processes can be computed by a universal Turing machine. Physical laws then become descriptions of subsets of actually observable, as opposed to merely possible, computations. Bell correlations imply a separation: Either beyond-Turing computations are impossible in nature, or they can be carried out even by single photons.

Morgan Weston, Griffith University, Australia. Entanglement is a key resource to many quantum information protocols, making rigorous verification of remote shared entanglement highly sought after. We design and experimentally implement a new heralded quantum steering protocol in order to verify shared entanglement over a high loss quantum channel, with the detection loophole closed. Our scheme uses entanglement swapping with two high-performance telecom-wavelength, polarisation-entangled photon sources and highly efficient detectors. Our approach has demonstrated violation of the steering inequality by two standard deviations with 14.8 dB of added channel loss, equivalent to approximately 80km of telecom fibre.

Joseph Ho, Griffith University, Australia. While the salient features of a quantum computer have been shown in proof-of-principle experiments, e.g., single- and two-qubit gates forming a universal gate set, difficulties in scaling up the quantum systems to control multiple qubits have made demonstrations of mode complex operations intractable. This is exemplified by the classical Fredkin (or controlled-SWAP) gate for which, despite many theoretical proposals, a true quantum analogue has yet to be realised. Here, by directly adding control to the two qubit SWAP unitary, we use photonic qubit logic to report on one of the first experimental demonstration of a quantum Fredkin gate.
