The drive to creat ever more powerful computers is spurring research into what's called quantum computing. Up to now, information stored and manipulated in computers relies on the flow of electrons within transistors. And it might seem that transistors and computers just keep getting smaller and more powerful. But eventually we will see the limit of what electronic transistors can do.

And that's where quantum computers come in. Earth and sky spoke with George Bourianoff, a scientist with Intel Corporation. Burianove said it might be possible someday to creat a quantum computer. In this computer of the future, individual atoms are controlled in such a way as to get them to store useful computer information. Buranove spoke of what physisists call entangled states. It's what happens when atoms interact with each other.

"That's the whole basis of quantum computer."

Bourianoff added there were at least 50 years away from seeing a true quantum computer. But there is some promising work with crystalline films that might come close.

We have an Earth & Sky clear voices podcast with Gorge Bourianoff on quantum computing at our website. Our thanks today to the National Science Foundation. I'm Deborah Byrd.

And I'm Joel Block for Earth & Sky, a clear voice for science. We are at Earthsky.org.
