Engineering Quantum Causes
Gerard J Milburn
(University of Queensland and Imperial College)
Date: Thursday 17 May 2018
Time: 17:00
Venue: Abreu Faro Amphitheatre, Interdisciplinary Building, IST, Lisbon
Abstract:
Are cause and effect objective facts about the world? Many philosophers doubt it. Physicists ground causation objectively in terms of Lorentz invariance: a central feature of quantum field theory. Yet the pioneers of quantum mechanics lamented the demise of classical causality and the violation of various Bell-like inequalities raise new questions. Nonetheless, advancing quantum communication technologies seek to exploit non classical quantum correlations to perform tasks impossible in a classical world. Quantum information theorists have recently discovered new quantum causal relations beyond Bell, yet the physical meaning of this discovery remains unclear. In this talk I will review some of the recent theories on classical and quantum causation and explain how ion trap quantum technologies might be used to engineer novel causal relations in a laboratory setting.
