Research Team Makes Quantum Computing Progress

Timogen writes to tell us Wired is reporting that a research team is reporting that they have found a way to "controllably couple qubits" bringing us one step closer to quantum computing. "In classical computer science, bits -- or binary digits -- hold data encoded as ones and zeros. In quantum computing, data is measured in qubits, or quantum bits. As such, a qubit can have three possible states -- one, zero or a "superposition" of one and zero. This unique property theoretically makes quantum computing able to solve large-scale calculations that would dwarf today's supercomputers. But qubits in isolation are not very useful. It's only when they can be connected to one another that large-scale processing becomes possible."

Interesting

It feels as if we were recreating computing, making the first steps again that were made during the 1920s-1940s in computing.

Re:Right what we needed

The Progress 4GL (and database) has a tri-valued boolean: true, false and unknown. There are times when it's useful, rather than saying "assume true" or "assume false", you can say "don't know yet".
