1/n #Quantum States as #Classical Sensors Dept: For work in #Precognition and #Augmented #Psi there are two generalizations useful for different purposes - The applications fork can be independent of theoretical constraints. In other words you can generate data for quantitative / qualitative corollation without asking what the mechanism is...
In the Foundational fork your looking for the theory - your trying to determine mechanism or some variable dependent on mechanism - encodings, signal...

2/n...signal spaces, noise parameters, whatever...

One of the more interesting aspects of recent research is that quantum "squirrelliness" or sensitivities you might normally expect in a confined quantum system when you poke it can leave suspect traces in semi bound classical systems. That lends support to the notion that nature is encoding the information we see in #Psi at two levels in parallel. Useful but it's early yet.
The other slightly more spine tingling thing is that if you require...

3/n... #Entanglement then there could be some operator that survives the ambient thermal bath, gives up some n bits of information, then collapses. In this context the experiment is indistinguishable from many other experiments in #QuantumMechanics and #QuantumInformation. If we were talking about #Precognition no one needs to know
