How the hell does a quantum computer work?
BBC News said:By Katia Moskvitch Science reporter, BBC News
Astronomers have detected an Earth-like exoplanet that may have just the right kind of conditions to support life.
Gliese 581g lies some 20 light-years away in its star's "Goldilocks zone" - a region surface temperatures would allow the presence of liquid water.
Scientists say that the newly found world could also potentially have an atmosphere.
Their findings, made with the Keck telescope in Hawaii, appear in the Astrophysical Journal.
The researchers, from the University of California at Santa Cruz (UCSC) and the Carnegie Institution of Washington, have been studying the movement of the planet's parent star, a red dwarf called Gliese 581, for 11 years.
Their observations have revealed a number of exoplanets spinning around the star.

^ A normal computer keeps track of data through bits, which can be in a state of either 1 or 0, but only one of those at a time. A quantum computer uses (or would us) "qubits" which can represent a 1, 0, or (using superposition), both of those states at the same time. A computer with n number of bits can be in one of 2^n states at a time, but a computer with n number of qubits can be in any number of 2^n states, essentially increasing the amount of memory and processing power exponentially.
That is a very simplified explanation. Clarify and expand upon that here.
I just wanna know how they measure surface temperature of a planet that's 20 light years away xD
At our current technology I think they'd have to send like 8 couples who then will have children, and those children (from the different couples to avoid inbreeding) will have children too... and perhaps those reach the planet.
Don't forget hundreds of thousands of years of constant full burn deceleration to stop :lol:
Schrodinger's hard drive?
Don't be silly. That's what the planet is for.
Must be interesting to go from 4 Gs to 0 instantly.
