    "abstract": "We have made the first experimental demonstration of the simultaneous minimum\nuncertainty product between two complementary observables for a two-state\nsystem (a qubit). A partially entangled two-photon state was used to perform\nsuch measurements. Each of the photons carries (partial) information of the\ninitial state thus leaving a room for measurements of two complementary\nobservables on every member in an ensemble.",
