Abstract: Protocols to exploit non-linear quantum mechanical effects to parallelize any process (such as computational, mechanical or biological), inhibit the dilution of non-linear quantum mechanical effects and enhance the shot noise limit of quantum measurement devices are described. The key concept behind these protocols is the use of a device that can communicate across different arms of a quantum superposition even in the presence of decoherence using non-linear quantum mechanical interactions (such as the expectation values of classical sources of electromagnetism and gravitation). By communicating across different arms of a quantum superposition, the protocol can collect the results of parallelizable tasks performed in each arm of the superposition, arrive at well defined final states across the superposition and use the strength of the observed non-linearity to measure the properties of the superposition itself.
