Quantum logic could make better robot bartenders

Creating robots with multiple personalities may be one way to make them act more like us.

Despite their reputation as a psychological disorder, we all have multiple personalities. Controlled personality switching helps us juggle our daily roles – as workers, parents and spouses, for instance. In contrast, robots are usually programmed to respond to situations by following a single set of rules, which makes them inflexible. To trigger a personality switch in robots, quantum logic, with its limitless and apparently random outcomes, could do the trick.
