    I recently have been researching Quantum Computing for an article I was writing. It's amazing how far along it has come. Google just recently hired Dr. Martinis from the University of California, Santa Barbara to help develop and working Quantum Computer. Google has been working with the DWave Two, but there is some controversy as to whether or not that is a fully quantum computer (it very likely is only quasi-quantum). This is a pretty cool development because there are all kinds of problems that could benefit from quantum computers. Problems that would take classical computers thousands of years. Just cool stuff.

    Google Leaps Into Quantum Computing (click at the top to close the annoying pop up)

    Here is the webpage for Dr. Martinis group

    I've read somewhere that a quantum computer can't be able to work on Earth because of the magnetic field surrounding Earth. Somehow that magnetism affects the computer and won't allow it to work.

    Hi Cosmictraveler,

    No, that's definitely a myth. It's true that qubits, especially large numbers of entangled qubits necessary for quantum computing, are delicate systems that are easily perturbed, but that's why Martinis' group puts so much effort into error correction. Not only are Quantum Computers capable of working on Earth, they will become an important part of computing in a myriad of applications over the next 50 years.

    Best Regards,
    Roger

    Thanks for the 411 and I hope to be around next year to see it in action. Do you happen to know why magnetic fields affect this type of computer, if it does.

    Hi Cosmictraveler,

    Magnetic fields effect regular computers as well! Just put a strong magnet near your hard drive to see what I mean. In general, qubits are more delicate than bits, so they are more easily perturbed. Not just from magnetic fields (though that is a good way to perturb any electrical system). The qubits are cooled to near absolute zero because just normal molecular vibration can disturb them. Without getting into the details, the delicate nature of qubits is directly related to their inherent parallelism. With great ability comes a delicate nature. Think of them as the Christian Bale of computers.

    I understand, thank you.
