Room 5 We are currently building a website which provides a mechanism for studying a broad community's \?rilling-ness to perform structured legal argumentation.' Visitors to the website are permitted to make moves in an argument game!; Their moves are entered in a format ii. Argument games are well-recognized as useful theories. Prominent examples for this… (More)
Using a spontaneous parametric-downconversion source of photon pairs, we are working towards the creation of arbitrary 2-qubit quantum states with high fidelity. Currently, all physically allowable combinations of polarization entanglement and mixture can be produced, including maximally-entangled mixed states. The states are experimentally measured and… (More)
Photon pairs sources based on nonlinear optical techniques are essential components in modern quantum optical systems. We present here a naturally occurring biological source of photon pairs - Green Fluorescent Protein (GFP) - obtained by a non-degenerate four-wave mixing (FWM).
