Quantum games

Research from LMU in Munich attempts to test if quantum particles, such as bosons, follow prescriptions of game theory, a well established concept in economics. This is in a favorable direction as it may simplify quantum behavior by using constructs from macro systems. The incentives for bosons to be on the same wavelength as their neighbors is akin to incentives present in human interactions. And, if a simple objective function, such as profits or wealth maximization can be found for quantum particles, then, their behavior could well be predicted by economic theory. It has been noted that, at the extreme, the Bose-Einstein condensate behaves like a single super particle. It is conceivable that if such behavior is universal, it has implications for design for truly advanced societies.

The divergence of the behavior of quantum systems from human scale systems has been problematic not only for physicists but also for amateurs who seek simplification. Intuition seems to point to missing attributes or perhaps a completely wrong theory. If quantum behavior could be explained by those seen in bigger systems, then the chance of survival increases for the theory itself. However, this implicitly assumes that bigger systems are a natural progression of quantum ones and most available information seems to refute such a notion. Engineering bias force scientists and technologists to a unified theory – from parts to the whole - and it is quite possible that multiple universes with differing laws exist within the observable one in human scale.

Whatever the reality, the notion of explaining quantum behavior using larger systems is intriguing. If this is possible, such behavior could provide direction for better designs of human systems as well.
