  • Science Tips, July 2007

    Four research updates from the Weizmann Institute: doping electronics; experiments with interfering electrons; a new model of molecular recognition; and a promising cellular reporter.

  • Science Tips, March 2013

    Three updates from the Weizmann Institute: scientists take steps toward building a complete, functional, artificial cell; progress is made toward understanding the measurement process in quantum systems; and a new study may help develop ways to control tissue destruction that results from inflammation and necrosis.

    Ultra-Cooling Gives Slow-Mo View of Quantum Physics

    In quantum physics, just observing something changes that thing immeasurably. Now, by supercooling atoms to slow them down, Prof. Ehud Altman and colleagues on an EU project are able to see these changes. As the European Commission's Horizon magazine says, ""the results are giving them a new perspective into the behaviour of matter at the quantum level.""

    One Atom + Two Photons = Quantum Computing Switch

    Dr. Barak Dayan and the quantum optics group at Weizmann have made a quantum computing breakthrough, recently published in Science. As IEEE Spectrum reports, Dr. Dayan can use a single atom to switch the direction of a single photon, which ""could pave the way toward quantum computers much more powerful than today's machines.""

    How to Reduce Shockwaves in Quantum Beam Experiments

    The tiny cone-shaped “skimmers” used in experiments looking for exotic chemical-quantum phenomena resemble the intake mechanisms of aircraft engines, and they perform similar functions: each directs the flow of gas – the engine intake controls the supply of air for burning fuel, and the “skimmer” creates beams of cold flying atoms or molecules. While skimmers have been a necessary component in atomic and molecular-beam experiments for decades, they were also known to impose a fundamental limit on the number of particles one could pack into the beam.

    Light Exchange

    The quantum computers of the future will be able to perform computations that cannot be done on today’s computers. These may likely include the ability to crack the encryption that is currently used for secure electronic transactions, as well as the means to efficiently solve unwieldy problems in which the number of possible solutions increases exponentially. Research in the quantum optics lab of Prof. Barak Dayan at the Weizmann Institute of Science may be bringing such computers one step closer by providing the “quantum gates” required for communication within and between such quantum computers.
