Microsoft's Cool Quantum Computing Plan Embraces Cryogenic Memory (pcworld.com) 39
An anonymous reader shares a PCWorld report: Microsoft has crazy quantum computing plans: first, it built hardware based on a particle that hasn't even been discovered. Now, it's hoping to co-design super-cool memory for quantum computers. The company is working with Rambus to develop and build prototype computers with memory subsystems that can be cooled at cryogenic temperatures, typically below minus 180 degrees Celsius or minus 292 degrees Fahrenheit. Cryogenics goes hand in hand with quantum computers, which promise to be significantly faster than today's PCs and servers and may even eventually replace them. But the systems are notoriously unstable and need to be stored in refrigerators for faster and secure operation. As an example, D-Wave's 2000Q quantum computer needs to be kept significantly cooler than supercomputers so operations don't break down.

Quantum-"computing" is not progress. It is a scam that may never work and will not work for any meaningful tasks anytime soon. Perfect for MS and Rambus, as the two companies have long end extensive experience with ripping off their customers.

Rambus is a scam too, so they fit in well.

Indeed. Like most of Quantum-"Computing" these days. Call me again when they can break RSA-300 or so, which was broken by conventional computers quite a while ago. The thing is, the number of entangled qbits seem to have been growing sub-linear with time. May well be that quantum computers scale inverse exponentially with effort, and that would mean somewhere is a border where you just cannot get more and that one seems to be pretty low. There may also be an actual hard boundary that no amount of effort can overcome. Hence, a few hundred qbits may be all that is possible in this universe. That is basically worthless.

Actually, the D-Wave is not faster than a conventional computer that is orders of magnitude cheaper. Simply use the best algorithm for each architecture. The only situation where the D-Wave is faster is if the conventional computer simulates the D-Wave. That does not make any sense, except as a marketing stunt for the gullible.

"A particle that doesn't exist yet"
Technically a particle system that is theorized to exist, but not yet isolated: An anyon particle system with a state degeneracy which exhibits non-Abelian particle exchange statistics.
Apparently, with such a particle system, it is possible to build a topological quantum computer.
Experimental physicists potentially observed such a system in nanowires made from the semiconductor indium antimonide. More recent experiments suggest that it is possible that ultra-pure, ultra-cold, ultra-magnetized gallium arsen

"A particle that doesn't exist yet"
Technically a particle system that is theorized to exist, but not yet isolated:
So does that imply a new type of particle in the usual sense (electrons, positrons, neutrinos etc) or in some more abstract sense?
The anyon particle is a more abstract type called a quasi-particle. An anyon would be an isolatable effect in a *real* system, where the system is constrained in a specific way. As a way of analogy, if you had an electron travelling through a semiconductor, you can think as a really complicated system of electrons travelling thorough a sea/lattice of nuclei, or you can think of it as a quasi-electron quantum particle travelling in a more homogeneous media. An Anyon is simply a ordinary particle constrain
