These are processed then by a computer algorithm and transmitted to electrodes attached to the subject knees,
researchers have been trying to build a computer that harnesses the enormous potential of quantum mechanics. Now engineers from the University of New south wales (UNSW) in Australia have overcome the final hurdle,
by creating a quantum logic gate in silicon-the same material that today's computer chips are made from.
Right now, regular computer chips store information as binary bits, which are either in a 0 or 1 state.
which isn't compatible with today's silicon-based computer infrastructure. A silicon quantum logic gate was the last physical building block remaining to be built
"Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs,
About 1 billion of these transistors has been packed onto each silicon chip in your smartphone or computer.
"These batteries could be used in computers, data stations, for lighting--anyplace batteries are used now.""Dai worked with Case Western Reserve postdoctor Jintao Zhang,
and involved the collaboration of chemists, cancer biologists, computer modeling experts, biochemists and biophysicists at KU--notably the labs of Xu, Jeffrey Aub in the Department of Medicinal Chemistry and Jon Tunge in the Department of chemistry.
Unlike conventional computers that store data on transistors and hard drives, quantum computers encode data in the quantum states of microscopic objects called qubits.
Moreover, this specific type of quantum bit can be manufactured using a similar technology to that employed for the production of everyday computers,

This is an important step on the way towards optical computers. Phase change materials that change their optical properties depending on the arrangement of the atoms allow for the storage of several bits in a single cell.
With optical elements, computers can work more rapidly and more efficiently. Optical fibers have long since been used for the transmission of data with light.
