EXCERPT: The quest for a meta-theory of quantum control [...] "I really like the direction of quantum cybernetics..." [says] Vlatko Vedral [...] Usually, quantum information processing is concerned with storing and transmitting information according to quantum mechanical laws, "but cybernetics also implies being able to use this information for self-regulation of the system."

[...Quantum cybernetics] could shed light on some mysterious biological processes that appear to be using a sprinkling of quantum magic to improve efficiency. Until recently, physicists had assumed that quantum effects were too fragile to survive in the warm and wet environments of cells, let alone that they could play a crucial role in macroscopic biological systems. However, over the past decade, there has been increasing evidence that plants and some algae exploit quantum effects to speed up photosynthesis, the process for converting sunlight to energy. Some physicists have also suggested that birds use quantum entanglement to help navigate magnetic fields.

Such examples of quantum biology have already blurred the line between the quantum and classical worlds. [...] So where does [Gerardo] Adesso think this line will be drawn? Will we one day describe politics in terms of quantum cybernetics? ...
