[Telegraph] Will the QC kill the PC?

post #1 of 62

Quantum computers could become a reality very soon, opening up some fantastic possibilities - including teleportation, says Richard Gray

It might be the science of the very small, but quantum computing is on the verge of solving some giant problems. For more than 30 years, physicists have dreamed of harnessing the power of atoms to produce computers that would far outstrip the capabilities of the silicon microchips used in today's PCs.

Quantum computers are a great concept but I am worried that if it falls under the wrong hand it can cause some serious Chaos .

Some scientists have estimated that even a very simple 30-qubit computer would be around 1,000 times faster than most desktop PCs. :O

This is just as ridiculous as the articles proclaiming that CUDA will kill the CPU. Quantum computing has a few applications for which it is unimaginably fast - factoring large numbers (important for cracking cryptography), the Traveling Salesman Problem (and others like it), etc. For arithmetic and ordinary logic, however, quantum computers are very ill suited and most likely slower than the heavily optimized architectures we have today.

Nehalem will get pwned!

J/k, since these will take a while to actually come out.

Maybe a QPU PCI card? Similar to how physics cards and graphics cards are only useful in certain areas a card with an onboard quantum processor could yield fantastic boosts for applications supporting it. Without totally forcing a switch. Best of both worlds and probably a cheaper solution too.

Lol, teleportation is real and possible and been done. (On a very small scale. It had something to do with laser bombardment.) Although i don't get how quantum computers are involved quantum physics are behind teleportation technologies.

I don't think any will be executing x86 code so it doesn't matter.

lol PCI? Will it have enough bandwidth?

Depends on how much data needs to be processed and how much the CPU will be needed to do it.
