Error in an argument regarding "improper" mixtures
K. A. Kirkpatrick
An argument, perhaps originating with Feyerabend a half century ago, and repeated many times since, purporting to establish that an "ignorance interpretation" of a bipartite pure e…
Compatibility and probability
K. A. Kirkpatrick
A review of various definitions of "compatibility" expressed in terms of ordinary probability, and a discussion of the occurrence of incompatibility (and the related phenomenon of…
Indistinguishability and the external correlation of mixtures
K. A. Kirkpatrick
Experimental evidence, the heuristics of indistinguishability, and its logical inconsistency with quantum formalism all argue against the existence of a quantum mixture uncorrelate…
The Schrodinger-HJW Theorem
K. A. Kirkpatrick
A concise presentation of Schrodinger's ancilla theorem (1936 Proc. Camb. Phil. Soc. 32, 446) and its several recent rediscoveries.
Hardy's Second Axiom is insufficiently general
K. A. Kirkpatrick
Hardy (quant-ph/0101012) conjectures in his Axiom 2 that K=K(N), and that in classical probability K=N, while in quantum mechanics K=N^2. We offer an example in classical probabili…
Ambiguities in the derivation of retrodictive probability
K. A. Kirkpatrick
The derivation of the quantum retrodictive probability formula involves an error, an ambiguity. The end result is correct because this error appears twice, in such a way as to canc…
