Conclusive exclusion of quantum states
... the wrong preparation with probability q. Note that 0 q 1/2, as Bob will always have the option of randomly guessing the description without performing an observation. If χ1 ∩ χ2 = ∅, then, even if Bob has access to the complete description of the system, λ, q > 0 as there will exist λ compat ...

A functional quantum programming language
... figure 1 to determine whether two classical bits, represented as qubits, are equal, which is based on Deutsch’s algorithm (see [12], pp.32). It exploits quantum parallelism by querying both inputs at the same time; this corresponds to the fact that the expressions if ◦ a and if ◦ b in our program ar ...

Heisenberg`s Uncertainty Principle is Dead
... I have already shown how this “uncertainty” creeps in to all macro measurements. I showed it in my analysis of the historical measurement of the speed of light from Mt. Wilson to Mt. Baldy.* And I showed it most recently in my analysis of the “neutrinos” going from Switzerland to Italy in the Great ...

Introducing categories to the practicing physicist
... Unit object and unit natural isomorphisms. Physical operations can destroy a system e.g. measurement of the position of a photon. On the other hand, one can conceive a preparation procedure as the creation of a system from an unspecified source. Therefore it is useful to have an object standing for ...

I am grateful to Mike Weismann for guiding much of this discussion
... consequence, measurement appears to serve the function of a selection, from among the more or less infinite possibilities allowed in Hilbert space, of just the few states permitted by conservation laws, in the so called “collapse of the wavefunction”. Measurement of one therefore appears to determin ...
