Quantum computing with recycled particles


A harmonic oscillator in classical mechanics (...

A harmonic oscillator in classical mechanics (A-B) and quantum mechanics (C-H). In (A-B), a ball, attached to a spring, oscillates back and forth. (C-H) are six solutions to the Schrödinger Equation for this situation. The horizontal axis is position, the vertical axis is the real part (blue) or imaginary part (red) of the wavefunction. (C,D,E,F), but not (G,H), are stationary states (energy eigenstates), which come from solutions to the Time-Independent Schrödinger Equation.

R&D Magazine – Using photons as the particles, the University of Bristol team constructed a quantum optical circuit that recycled one of the photons to set a new record for factoring 21 with a quantum algorithm—all previous demonstrations have factored 15.

Anthony Laing, who led the project, says, “Quantum computers promise to harness the counterintuitive laws of quantum mechanics to perform calculations that are forever out of reach of conventional classical computers. Realizing such a device is one of the great technological challenges of the century.” more> http://tinyurl.com/8mwszds
