Decoherence and ‘Quantum Darwinism’: not a cure for Schrodinger’s Cat.

It is widely thought that decoherence solves the measurement problem in a Many Worlds approach to quantum theory. In fact, this is claimed to be settled science in many internet sites with information on quantum theory. But this is not correct. Those 'Quantum Darwinism' arguments depend on smuggling in a hidden premise that is inconsistent … Continue reading Decoherence and ‘Quantum Darwinism’: not a cure for Schrodinger’s Cat. →

Why quantum theory isn’t a shell game (PBR Theorem for the layperson)

The following is an excerpt from an Appendix of my forthcoming book, Understanding Our Unseen Reality: Resolving Quantum Riddles (Imperial College Press). In the book, quantum states (‘kets’) are represented by triangles. The proof of Pusey, Barrett and Rudolph demonstrates that quantum states cannot be taken as approximate descriptions of underlying, hidden properties. To present … Continue reading Why quantum theory isn’t a shell game (PBR Theorem for the layperson) →

Reply to Peter Lewis — to appear in SHPMP

Maudlin’s Challenge Refuted:  A Reply to Lewis R. E. Kastner University of Maryland, College Park 10 March 2014 ABSTRACT.  Lewis has recently argued that Maudlin’s contingent absorber experiment remains a significant problem for the Transactional Interpretation (TI).  He argues that the only straightforward way to resolve the challenge is by describing the absorbers as offer … Continue reading Reply to Peter Lewis — to appear in SHPMP →

New review of my book by M. Probert

Extract: "There have been many objections to the TI over the years, most famously by Tim Maudlin in his book Quantum Nonlocality and Relativity.This is where Kastner comes into her own, with her own updated version of TI called 'possibilist transactional interpretation'which keeps all the key ideas of Cramer but extends the philosophical basis of … Continue reading New review of my book by M. Probert →
