There are distinct PHYSICAL and DYNAMICAL reasons why robust classical computation is possible. not all physical systems are equally good for computation: there exist systems whose PHYSICS guarantees their ability to enact robust classical computation. What is the phase of matter corresponding to th ...

... Wavefunction ψ (Psi) describes a quantum mechanical system. The nature of a system can be described by probabilistic values; probability of an event is equal to the square of the amplitude of the wavefunction (|ψ|²). Impossible to know all properties of a system at the same time, each must be given ...

... Equation 2, though simple, has profound consequences. To analyze them, start with a misstep: In an attempt to simplify, divide by ⟨u ∣ v⟩. The result is ⟨A0 ∣ A0 ⟩ = ⟨Au ∣ Av ⟩, or ⟨Au ∣ Av ⟩ = 1. That unit value implies ∣Au ⟩ = ∣Av ⟩. In other words, the apparatus cannot distinguish ∣u⟩ fro ∣v⟩. I ...
