(PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation has been performed on a photonic chip and it is major step forward in the quest to realise a super-powerful quantum computer. http://www.physorg.com/news171213314.html Physics Thu, 03 Sep 2009 16:15:49 EST news171213314 (PhysOrg.com) -- Two Dartmouth researchers have found a way to develop more robust `quantum gates,` which are the elementary building blocks of quantum circuits. Quantum circuits, someday, will be used to operate quantum computers, super powerful computers that have the potential to perform extremely complex algorithms quickly and efficiently. http://www.physorg.com/news156101597.html Physics Thu, 12 Mar 2009 18:33:49 EST news156101597 (PhysOrg.com) -- `Fock states will play a role in the future of quantum computing,` Andrew Cleland tells PhysOrg.com. `We have completed the first experimental measurement of the time decay of Fock states in a superconducting quantum circuit, and we believe this will provide useful information as we work toward developing a quantum computer.` Cleland is a professor at the University of California, Santa Barbara, and works with a group headed by John Martinis. http://www.physorg.com/news149252720.html Physics Tue, 23 Dec 2008 11:05:20 EST news149252720
