S&TR Preview: Quantum Computing Is Here


quantum computing offers the possibility
of exponential speed ups in certain types of calculations or what you could
ever be achieved on the classical computer the basic difference between quantum and
classical computers is how they manipulate information in a classical
computer if you have a series of decisions you can only make one set of
decisions one path and in that decision space at a time and in lots of problems
the number of decisions you need to make grows exponentially if they depend on
each other in a quantum system you don’t have to do one at a time you can take
both paths and so you can consider the case this is true and false and then you
can look at the consequence of that true and false and so on and just like in if
the chinko parlor the rather than taking one path down for that ball in the
quantum case you can take all paths and in the very end of the calculation you
use what’s called quantum interference that to collect your result about say
the optimal route through through that decision space quantum computing is hard
in order to do a calculation we have to come in from the classical world give
the quantum system instructions without messing it up and get it to come to some
result quantum computing still in its infancy it’s a bit like the early days
of classical competing when the transistor was first developed we have
the basic building blocks but we need to figure out how to put them together and
that challenge is something that spans many disciplines from basic science to
engineering computation high-performance computing
and applications and the lab is a place where we have those capabilities and so
it’s an ideal place to to pursue this as a and move the field forward another key
aspect of the lab that’s relevant for this kind of work is that we have a
mission and so everything we’re doing is geared towards realizing that mission
means we have an objective and that actually has a strong impact on how we
perform the work and how we move it forward
the main component of our quantum testbed is a superconducting aluminum
quantum processor what makes our quantum processor unique is its elegant
simplicity it is a resource efficient design so that we get the most
computational power in the smallest footprint the rest of the system is
designed so we can make the processor work we put the processor inside a
cryogen free dilution refrigerator and the compressor reduces the temperature
inside the refrigeration tank to about three Kelvin the electronics around our
quantum test bed serve two purposes the first is a classical to quantum
converter so that we can ask our processor a question the second is as a
quantum to classical converter so we can see the answer to that question a
quantum testbed didn’t come configured there isn’t an instruction manual for
how to put together a quantum computer instead we use the labs mission need to
drive our unique design choices and all of the electronics that make up the con
computing system you

    From the description given I don't understand how this is different from parallel processing (with conventional computers) instead of working though each decision tree one at a time in an iterative manor in the "classic" computing model. How are you re-modeling the parts/actions of a CPU? in what type of materials? How many FLOPS? Can you factor RSA/EC keys yet with it? So many questions…

    Same as announcing live tv as CGI, but real.

    Great expectations about quantum AR and regular TV.

    Make anchor that grandma loves strip.
