and perhaps a nice martini. We still don t have the full picture, but there s currently reason to give some of the tech companies at least a limited break.
Now John Martinis a professor at University of California Santa barbara has joined Google to establish a new quantum hardware lab near the university.
Martinis has spent more than a decade working on a more proven approach to quantum computing and built some of the largest most error-free systems of qubits the basic building blocks that encode information in a quantum computer.
and make the qubits in a different way says Martinis of his effort to improve on D-Wave s hardware.
Martinis has taken a joint position with Google and UCSB that will allow him to continue his own research at the university.
Martinis s previous work has been focused on the conventional approach to quantum computing. He set a new milestone in the field this April
Martinis was a coauthor on a paper published in Science earlier this year that took the most rigorous independent look at A d-Wave machine yet.
Martinis s work on D-Wave s machine led him into talks with Google and to his new position.
Martinis thinks his technology for fabricating qubits could make better quantum annealers. Specifically he hopes to make one
Martinis has built qubits that can do that for as long as 30 microseconds he says. Martinis makes his qubits from aluminum circuits built on sapphire wafers
and chills them to 20 millikelvin a fraction above absolute zero so that they become superconducting. D-Wave s chip requires similar cooling to operate
Martinis is in the process of switching to making his own qubits on silicon and believes certain electrical insulator materials used in D-Wave s chips may be limiting its performance.
But, before that happens, quantum physicists like the ones in UC Santa barbara's physics professor John Martinis'lab will have to create circuitry that takes advantage of the marvelous computing prowess promised by the quantum bit("qubit),
the researchers in the Martinis Lab have developed quantum circuitry that self-checks for errors and suppresses them,
However, that obstacle may just have been cleared by Kelly, postdoctoral researcher Rami Barends, staff scientist Austin Fowler and others in the Martinis Group.
"The Martinis Group continues to refine its research to develop this important new tool. This particular quantum error correction has been proved to protect against the"bit-flip"error,
Martinis and the senior members of his research group have, since this research was performed, entered into a partnership with Google.##
