26 - 28 October 2011: Workshop on Foundations of Quantum Theory: measurement, the quantum to classical transition, and the flow of time
An International Workshop on the foundations of quantum physics will take place from Wednesday 26th to Friday 28th of October 2011 at the Stellenbosch Institute for Advanced Study (STIAS)

Wednesday 26 October 2011 to Friday 28 October 2011
The workshop will focus on the relation between quantum measurement, the flow of time, and the quantum to classical transition. These issues have implications for our view on what kinds of existence are represented by classical and quantum states, and what are the relations between them.
This will be an opportunity for local workers to interact with high-level speakers from overseas on these foundational issues, and hence will develop the topic in general but also promote its discussion and development in the African context in particular.
Apart from the usual themes related to foundations of quantum theory, there are four specific issues at stake that are not so often examined. Firstly, should we consider classical or quantum objects as primary? Both views have been held. Secondly, is the wave function a physical or mental construct? The nature of the collapse problem is quite different in these two cases. Thirdly, however one construes that process, how does quantum measurement relate to irreversibility and the flow of time? Fourthly, does it somehow enable one to influence events that seem to be in the past? This is possible on some views.
The workshop will be a small three day focused meeting on these issues, with four talks each day. Thus there will twelve speakers, plus about twenty observers. This format will allow in depth discussions where the speakers will have real time to interact with each other.
The following questions will be addressed:
• What have we learned from fundamental experiments recently?
• Clauser and Horne in their first review of Bell and EPR conclude that either our notions of space and time need to be modified, or own understanding of reality. Therefore, which approaches to reality (or objectivity) and locality (or space-time) have been ruled out thus far?
• More precisely, which combinations of fundamental reasoning and methodology have become untenable? Which are still tenable?
• If there were ever a new theory beyond present quantum physics, how could we find it? Experimentally? Or theoretically?
• Which features of the present theory will by necessity be also part of the new theory?
