    Schrödinger's cat now has a second box to play in, thanks to an international team of physicists that has created a two-mode "Schrödinger's cat state" for the first time. The experiment brings together two purely quantum properties, in that the "cat" (i.e. the photons) is simultaneously "alive and dead" (in a superposition of states) while also in two locations at once (the two boxes are entangled with one another).

    Yale physicists have given Schrödinger's cat a second box to play in. Credit: Michael S. Helfenbein/Yale University ====================================================================================================================== Yale physicists have given Schrödinger's famous cat a second box to play in, and the result may help further the quest for reliable quantum computing. Schrödinger's cat is a well-known paradox that applies the concept of superposition in quantum physics to objects encountered in everyday life. The idea is that a cat is placed in a sealed box with a radioactive source and a poison that will be triggered if an atom of the radioactive substance decays. Quantum physics suggests that the...

    In a paper published in the current issue of the scientific journal Nature Communications and titled "Direct measurement of a 27-dimensional orbital-angular-momentum state vector," a team of physicists led by the University of Rochester's Mehul Malik describe how they circumvented a basic principle of uncertainty that requires that some states of a quantum system must be understood poorly if other states are to be understood well. Determining a quantum state, such as the position of an electron or the momentum of a photon, is tricky, to say the least. That's because subatomic particles behave nothing at all like billiard balls,...

    Schrodinger's Cat A cat is placed in a box, together with a radioactive atom. If the atom decays, a hammer kills the cat; if the atom doesn't decay, the cat lives. As the atom is considered to be in either state before the observer opens the box, the cat must thus be considered to be simultaneously dead and alive. -ERWIN SCHODINGER'S CAT PARADOX, 1935 Wittgenstein's Banana A banana is flying first class from New York to L.A.
