This Week in Tech: What on Earth Is a Quantum Computer? (via Qpute.com)

David Bacon, senior software program engineer in Google’s quantum lab: Quantum computer systems do computations in parallel universes. This by itself isn’t helpful. U solely get to exist in 1 universe at a time! The trick: quantum computer systems don’t simply cut up universes, in addition they merge universes. And this merge can add and subtract these different cut up universes.

David Reilly, principal researcher and director of the Microsoft quantum computing lab in Sydney, Australia: A quantum machine is a sort of analog calculator that computes by encoding info within the ephemeral waves that comprise gentle and matter on the nanoscale. Quantum entanglement — possible probably the most counterintuitive factor round — holds all of it collectively, detecting and fixing errors.

Daniel Lidar, professor {of electrical} and laptop engineering, chemistry, and physics and astronomy on the College of Southern California, along with his daughter Nina, in haiku:

Quantum computer systems
resolve some issues a lot quicker
however are vulnerable to noise

to discover a number of paths
to the correct reply

Interference helps:
cancels paths to unsuitable solutions
and boosts the correct ones

Entanglement makes
classical computer systems sweat,
QCs win the race

Scott Aaronson, professor of laptop science on the College of Texas at Austin: A quantum laptop exploits interference amongst constructive and unfavourable sq. roots of chances to resolve sure issues a lot quicker than we predict attainable classically, in a manner that wouldn’t be almost so fascinating had been it attainable to clarify within the house of a tweet.

Alan Baratz, govt vp of analysis and growth at D-Wave Methods: If we’re trustworthy, all the things we at the moment learn about quantum mechanics can’t totally describe how a quantum laptop works. What’s extra necessary, and much more fascinating, is what a quantum laptop can do: A.I., new molecules, new supplies, modeling local weather change …
