Quantum complexity – a few scattered thoughts about the current science-vs.-religion debate and the foundations of quantum mechanics // Microwave photons and superconducting qubits
Speaker:Sorin Paraoanu (Low Temperature Laboratory, Helsinki University of Technology)
Abstract:Quantum complexity – a few scattered thoughts about the current science-vs.-religion debate and the foundations of quantum mechanics: In the present cultural context the discussion about the relation between science and religion is dominated by the loud dispute between evolution theory and intelligent design/creationism. This attracts a lot of public interest but it is not, in my view, a truly relevant issue for theology. I will argue that, despite recent claims, evolution theory and science in general cannot be used to validate atheism. In contradistinction, theories such as quantum mechanics and relativity could offer powerful analogies for theology and also a more solid background for a deeper discussion about what exists and about our ability to understand the Universe. One of the foundational problems with such a potential in quantum physics is how the classical reality is recovered. I will discuss the case of systems with a high degree of quantum complexity and conjecture that there could be a connection between classicality and our ability to imprint various many-body states on such systems. // Microwave photons and superconducting qubits: In this part of the talk I will very briefly mention some of the physics related to the study of Josephson superconducting circuits and our own experimental and theoretical efforts in this direction. These circuits consist of qubits (two-level systems such as rf-squids, Cooper pair boxes, etc.) connected by quantum buses (superconducting waveguide resonators). I will argue that these systems offer a powerful platform for experimentally investigating how quantum mechanics works at the macroscopic scale.
