A team of researchers in Germany and at the University of Michigan have demonstrated how infrared laser pulses can shift electrons between two different states, the classic 1 and 0, in a thin sheet of semiconductor

"Ordinary electronics are in the range of gigahertz, one billion operations per second. This method is a million times faster," said Mackillo Kira, U-M professor of electrical engineering and computer science.

He led the theoretical part of the study, to be published in the journal Nature, collaborating with physicists at the University of Marburg in Germany. The experiment was done at the University of Regensburg in Germany.

[... Quantum computer] qubits are hard to make because quantum states are extremely fragile. The main commercial route, pursued by companies such as Intel, IBM, Microsoft and D-Wave, uses superconducting circuits—loops of wire cooled to extremely cold temperatures (-321°F or less), at which the electrons stop colliding with each other and instead form shared quantum states through a phenomenon known as coherence.

Rather than finding a way to hang onto a quantum state for a long time, the new study demonstrates a way to do the processing before the states fall apart.

"In the long run, we see a realistic chance of introducing quantum information devices that perform operations faster than a single oscillation of a lightwave," said Rupert Huber, professor of physics at the University of Regensburg, who led the experiment. "The material is relatively easy to make, it works in room temperature air, and at just a few atoms thick, it is maximally compact."

    I was with you up to this line,
    > Only God and a few elites know what these devices will have as hidden agendas.

    We're similar except that I believe in one less God than you believe in.
    As well as the elites, there will also be all the programmers that work for the elites, and also all the crackers (hackers) that access/"steal" collected data.
