Quantum Computing Again

I have to see this after looking at pathfinding algorithms for a while now...

 

This startup called D-Wave claims they'll have a prototype quantum computing device by 2006, for solving "optimizaton" problems like pathfinding (as well as quantum simulation problems).

 

Their qubits are relatively large scale loops of BCS superconductors (aluminum and niobium). Their devices are not intended for the "facotring big numbers" problem, but for setting up potentials and finding optimum paths, states of molecules with lots of electrons, etc.

 

Just thought that was interesting, and will be especially intersting if they can actually meet their 2006 deadline for a prototype.

So what does this mean for computing in general? When will we see comercial quantum computers make an appearence? Got any weblinks? sounds intriguing... :unsure:

Oh yeah, forgot to link it. Oops. Their site is pretty vague, I saw it in a magazine article. They say they're taking advantage of how macroscopic BCS superconductor loops can exhibit quantum phenomenon.

 

Maybe it's similar to designs that use spin quantum number of a trapped electron as a qubit, but instead of electron spin it uses the direction of current flow in macroscopic superconducting rings? I'm not sure.

      Does anyone actually use the Normalise button in the Surface inspector? Even after looking at the code I'm not quite sure what it's for.

      Turns out my 15th anniversary mission idea has already been done once or twice before! I've been beaten to the punch once again, but I suppose that's to be expected when there's over 170 FMs out there, eh? I'm not complaining though, I love learning new tricks and taking inspiration from past FMs. Best of luck on your own fan missions!

      I wanna play Doom 3, but fhDoom has much better features than dhewm3, yet fhDoom is old, outdated and probably not supported. Damn!
      Makes me think that TDM engine for Doom 3 itself would actually be perfect.

      Maybe a bit of advice ? In the FM series I'm preparing, the two main characters have the given names Toby and Agnes (it's the protagonist and deuteragonist, respectively), I've been toying with the idea of giving them family names as well, since many of the FM series have named protagonists who have surnames. Toby's from a family who were usually farriers, though he eventually wound up working as a cobbler (this serves as a daylight "front" for his night time thieving). Would it make sense if the man's popularly accepted family name was Farrier ? It's an existing, though less common English surname, and it directly refers to the profession practiced by his relatives. Your suggestions ?

      Looks like the "Reverse April Fools" releases were too well hidden. Darkfate still hasn't acknowledge all the new releases. Did you play any of the new April Fools missions?
