Simple Physical Systems May Yield Powerful Quantum Computers

Quantum computers are devices — still largely theoretical — that could perform certain types of computations much faster than classical computers; one way they might do that is by exploiting “spin,” a property of tiny particles of matter. A “spin chain,” in turn, is a standard model that physicists use to describe systems of quantum particles, including some that could be the basis for quantum computers.

Study Reveals Preferred Direction of Time's Quantum Arrow

Time marches relentlessly forward for you and me; watch a movie in reverse, and you'll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse – a concept known as time reversal symmetry.

King's College London Researcher Seeks Answer to Beat Quantum Crime

A future quantum computer will be able to carry out calculations billions of times faster than even today's most powerful machines by exploit the fact that the tiniest particles, molecules, atoms and subatomic particles can exist in more than one state simultaneously. Scientists and engineers are looking forward to working with such high-power machines but so too are cyber-criminals who will be able to exploit this power in cracking passwords and decrypting secret messages much faster than they can now.

Harnessing Dark Mode to Convert Optical Fields May Boost Quantum Computing

Using tiny radiation pressure forces -- generated each time light is reflected off a surface -- University of Oregon physicists converted an optical field, or signal, from one color to another. Aided by a "dark mode," the conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.

Quantum Weirdness Observed in Computer Chip Nanoelectronics

To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter.
