Light-based Quantum Circuit Does Basic Maths

Stochastism writes "In yet another small step toward realistic quantum computing Australian researchers have developed a light based 4-qubit quantum computer. It has already calculated the prime roots of fifteen, three and five. 'The quantum circuit pioneered by the Queensland researchers involves using a laser to send "entangled" photons through a linear optical circuit ... The Queensland research group acknowledged that the theorised code cracking ability of quantum computers may be why Australian quantum computer research is in part funded by a US government defence intelligence agency, the Defense Advanced Research Projects Agency (DARPA).'"

How many maths does it do?

[InvisblePinkUnicorn]

Seven! It does seven maths!

But...

[SiriusStarr]

More importantly, can it run Crysis?

In yet another small step toward realistic quantum computing Australian researchers have developed a light based 4-qubit quantum computer.

4 qubits? How much is that in furlongs?

hectares?

Moore's law

[pwnies]

I wonder if Moore's law will apply to the number of qubits within a quantum computer as well. A 1024 qubit computer within the next 20 years would be nice.

The similarity to bits only occurs once you open the box.
Until that point a cubit represents a dead cat.

Huh?

Prime roots of three and five? Boy, the quantum world is weird!...

Parse error! Parse error!

Me too!

[Daffy Duck]

It has already calculated the prime roots of fifteen, three and five.

I, too, have already calculated the prime roots of fifteen, with nearly identical results. Where's my DARPA funding?

It will be nice. But it still won't be able to figure out if that email message you got is spam, not spam, or some combination of both until you read it.

Prime roots, eh?

Nobody would ever be able to use 1024 qubits.

When you are in the bathematics make sure you don't use all the hot waters.

There's more Americans who speak English than there are British. Therefore, we win! Majority rule!

Wasn't Noah's ark 300 qubits? Noah was the man! Take that Silicon Devil!

Can't stop myself...oh the Humoranity!

[GeekZilla]

Q: What kind of room is it kept it?
A: A Qubicle

Q: How big is it?
A: About four Qubit meters.

Q: Qubit? Wasn't that an early arcade game with a little guy jumping around changing the quantum state of a bunch of Qubes?

I have OBVIOUSLY had too much Qaffeine.

Re:MATH

[SeekerDarksteel]

Mathematical of course. Because this is English. We don't remove suffixes, we ADD them.

Australia spoke English, last time I checked.

You've apparently never taken a look at the lyrics to Waltzing Matilda [wikipedia.org].

Computerized Australian Technology...until you take a good look at it.

That's no big deal

[p3d0]

I once new a guy who could compute the prime roots of 15 in his head.

It's obvious that

So basically, technology has given us quantum computers in the future, but users are still stupid enough to deliberately put Windoze on a Macintosh machine?

That says something about life.

CRAP! 15 was my RSA public key!
