Title: Einstein’s elements of reality, entanglement, and understanding the quantum to classical transition

Abstract: Einstein had reservations about the interpretation of quantum mechanics. Along with Podolsky and Rosen (EPR), he presented in 1935 an argument that quantum mechanics is not a complete theory. The objections raised by EPR concerned how to develop consistency between quantum mechanics and the “elements of reality” that seemed to exist for certain quantum states, based on what (at the time) appeared to be a fundamentally correct hypothesis: “no spooky action at-a-distance”, or “Local Realism”. The EPR paradox led to the concepts of entanglement and steering, pioneered by Schrödinger, and to the paradox of Schrödinger’s cat. A measurement couples a microscopic system to a macroscopic system, and it is unclear how to interpret the reality of the macroscopic system, the analogy being a cat coupled to a quantum device apparently ending up “both dead and alive”. Subsequently, Bell proved a theorem that eventually enabled the falsification of Local Realism. This work added to the debate over the meaning of quantum mechanics, and gave the underpinning for the new field of quantum information.

I begin with an outline of these discoveries, and summarize different interpretations of quantum mechanics that have been proposed to resolve the measurement paradox, including many-worlds and decoherence collapse models. I discuss some recent ideas and experiments to test these interpretations, including experiments to detect the mutual steering and entanglement of 40,000 atoms in a Bose–Einstein atom interferometer, along with new tests of macroscopic realism. Lastly, I discuss the paradox of the Schrödinger cat, using insight gained from phase-space distributions.

About Professor Margaret Reid

Prof Margaret Reid Margaret Reid is currently a Professor in physics at Swinburne University of Technology in Melbourne and is a Fellow of the Australian Academy of Science. She completed her PhD and postdoctoral studies at the University of Auckland and University of Waikato in New Zealand, working on theories for squeezed states of light and quantum non-demolition measurements. She also conducted research at ATT Bell Laboratories, in the USA. Over this period, she developed the atomic theory for the first experiment creating squeezed light, and proposed squeezing in connection with entanglement, which has had impact for quantum noise reduction. Subsequently, she worked as a QEII Fellow at the University of Queensland, Australia and as a Chief Investigator for the Australian Research Council Centre of Excellence in Quantum Atom Optics. Her significant contribution has been to establish the connection between parametric amplification, the two-mode squeezed state, and the Einstein–Podolsky–Rosen paradox. This gave a way to test the paradox and established a source for continuous variable quantum information. For contributions to the fields of quantum entanglement and non-locality, she has been made a Fellow of the Optical Society of America and a Fellow of the American Physical Society, and was recently awarded a visiting position at Harvard University and a JILA Fellowship at the University of Colorado, USA.
