We hear news of FXI preparing to launch the Cotton Candy, a tiny computer that looks like a USB thumb drive. The device, which can run either Ubuntu or Android 4.0, has a dual-core 1.2GHz ARM Cortex-A9 CPU, 1GB of RAM, and a Mali 400MP GPU that allows it to decode high-definition video.
And as our classical computer architectures shrink to sizes that were unimaginable 30 years ago, IBM reveals more details of its quest for the "next generation of computing".
In quantum computing, conventional binary bits are replaced by qubits, which can be 1, 0 or both. However, until now, qubits have been unstable: the pesky things tend to lose their quantum mechanical properties and go incoherent in a fraction of a second.
"The special properties of qubits will allow quantum computers to work on millions of computations at once, while desktop PCs can typically handle minimal simultaneous computations," the IBM researchers said. "For example, a single 250-qubit state contains more bits of information than there are atoms in the universe.
“In the past, people have said, maybe it’s 50 years away, it’s a dream, maybe it’ll happen sometime,” said Mark B. Ketchen, manager of the physics of information group at IBM.’s Thomas J. Watson Research Center in Yorktown Heights, New York. “I used to think it was 50. Now I’m thinking like it’s 15 or a little more. It’s within reach. It’s within our lifetime. It’s going to happen.”
Let's keep watching. If things follow through as they are predicting, and no major catastrophe hits humanity in the next decades, we could witness a leap in computational power within our lifetimes that will be unbelievably revolutionary - to say the least.
