The Perimeter Institute for Theoretical Physics has just opened a new facility in uptown Waterloo. Some friends of mine went to check out the grand opening.
Sounds like a really impressive facility, though I thought it rather odd that the tour was so regimented (follow in a line, no diverting from the tour path).

They'll be doing work on quantum gravity, string theory, quantum information theory, and the like. Of these, only the last has immediate applications, namely the possibility of making computers far more powerful than anything we have today.

I think it's funded by a big donation from the CEO of RIMS, the company that makes Blackberries. He did a degree (physics?) at Waterloo, but then decided to go into business. Clearly, he did pretty well for himself, but he wants to make it easier for people who want to, to do scientific research in academia.

This just a distillation of things I've heard so it may not be 100% accurate.

I think "immediate applications" might be an optimistic way to describe quantum computing. I think the most memory anyone has managed to create for a quantum computer, yet, is about 2 bits. Yup, bits. 8 of them make a byte, 1000 bytes make a K... so we're still pretty far from factoring large numbers (one of the things that, in theory, we have an idea of how to make quantum computers do)

And Mike, any comment from your friends about whether there are blackboards in the washrooms? (I heard a rumour...)

They didn't say that specifically, but they did say that every wall of every room seemed to be either glass or a blackboard.

Well, if we can assume that the washrooms don't have too many walls that are glass, it would seem to follow...

Including the outside southfacing wall (it looks like a blackboard, that is).

Incidentally, Mike Lazaridis dropped out of the University of Waterloo before getting his degree, but he's subsequently been given an honourary one.

Hah! I thought I was making a disparaging remark about the architecture, but it turns out that they made it look that way on purpose

Excerpt of an article from Saturday's Kitchener-Waterloo Record :

quote:
So what's with the big black wall on the building's south side?

"Lots of people have their own interpretations," says Howard Burton, executive director of the Perimeter Institute.

Among the interpretations:

a) It is unfinished.
b) It has a practical purpose.
c) The architects like black.
d) It represents different points of debate within science.
e) It was inspired by a testing chamber at Research In Motion.

"It's an interesting question," says architect Andre Perrotte.

His answer? Basically, if you're puzzled by the black wall, you should be.

"We wanted to create a little bit on the public the feeling that we don't understand science," Perrotte says.

"There's always something in science that needs to be interpreted by researchers."

Think of it as a giant blackboard, opaque to represent what's unknown about science, and textured to represent mysterious mathematical equations inside the building.

"We were amazed how much these researchers, they work with things that you and I don't understand," Perrotte says. "But they do it with chalk and blackboards."

Perrotte says there is an order to the way panels and windows extrude from the black wall, but the order is not meant to be evident.

"It's a bit like science," he says. "You and I know there is an order or a reason behind things, but we don't need to know it sometimes to use it."

For practical purposes, the wall also provides a screen for the private, contemplative north side of the building.


For those who aren't in the neighbourhood, it looks like this

Actually, quantum computers use something called quantum bits or qubits, which aren't the same as regular bits. So, if you heard that the best quantum computers only use 2 bits, it should have been 2 qubits. There have been some advances recently and quantum computers can be built with 8 or 9 qubits. This doesn't sound like much either, but a computer with a few hundred qubits would blow today's best classical supercomputer out of the water.

D-Wave Systems in Vancouver plans to have a quantum computer ready for large scale computations within 5 years. And I wouldn't bet against them.

For certain tasks, yeah.
The quantum thing is great for decryption. But most tasks aren't like that--they require not so much winnowing out answers from lots of possibilities, as straightforward transformations of one number to the next and the next. For that, you want raw speed and memory size. A few-hundred-qubit computer isn't going to hold a large spreadsheet in memory or run Doom 3.
