Quantum Computation Research Center in Singapore

Singapore is setting up a $98M research center for quantum computation.

Great news, but what in the world does this quote mean?

Professor Artur Ekert, Director, Research Centre of Excellence, said: “At the moment, you can buy quantum cryptography systems, you can use it in some simple applications but somehow you have to trust companies that sell it to you or you have to test the equipment.

“The kind of quantum cryptography we develop here is probably the most sophisticated that is not available in any other countries so we have some ideas to make it so secure that you don’t even have to trust equipment that you could buy from a vendor.”

Quantum Computing Just Got More Bizarre

You don’t even have to turn it on:

With the right set-up, the theory suggested, the computer would sometimes get an answer out of the computer even though the program did not run. And now researchers from the University of Illinois at Urbana-Champaign have improved on the original design and built a non-running quantum computer that really works.

So now, even turning the machine off won’t necessarily prevent hackers from stealing passwords.

And as long as we’re on the topic of quantum computing, here’s a piece of quantum snake oil:

A University of Toronto professor says he can now use a photon of light to smash through the most sophisticated computer theft schemes that hackers can devise.

EDITED TO ADD (3/1): More information about the University of Illinois result is here.
