John Bell on 'Subject and Object': an Exchange
Hans Halvorson, Jeremy Butterfield
This three-part paper comprises: (i) a critique by Halvorson of Bell's (1973) paper "Subject and Object"; (ii) a comment by Butterfield; (iii) a reply by Halvorson. An Appendix giv…
How is spontaneous symmetry breaking possible?
David John Baker, Hans Halvorson
We pose and resolve a seeming paradox about spontaneous symmetry breaking in the quantum theory of infinite systems. For a symmetry to be spontaneously broken, it must not be imple…
Can quantum cryptography imply quantum mechanics? Reply to Smolin
Hans Halvorson, Jeffrey Bub
Clifton, Bub, and Halvorson (CBH) have argued that quantum mechanics can be derived from three cryptographic, or broadly information-theoretic, axioms. But Smolin disagrees, and he…
A note on information theoretic characterizations of physical theories
Hans Halvorson
Clifton, Bub, and Halvorson [Foundations of Physics 33, 1561 (2003)] have recently argued that quantum theory is characterized by its satisfaction of three information-theoretic ax…
Remote preparation of arbitrary ensembles and quantum bit commitment
Hans Halvorson
The Hughston-Jozsa-Wootters theorem shows that any finite ensemble of quantum states can be prepared "at a distance", and it has been used to demonstrate the insecurity of all bit…
Characterizing quantum theory in terms of information-theoretic constraints
Rob Clifton, Jeffrey Bub, Hans Halvorson
We show that three fundamental information-theoretic constraints--the impossibility of superluminal information transfer between two physical systems by performing measurements on…
