#TIQW (The Isolated Quantum Worlds, September 07, 2019):

Is there a rhinoceros in the room? Is the quantum world aesthetically weird? Are quantum systems only small? What is macroscopicness? Is there quantum behavior, but no quantum objects? Why is (?) there randomness, but not superposition (say), in the manifest world? Is the World one unified physical system? Are there local hidden variables? Can reality/realism be local? Can detectors detect determinate outcomes while themselves not being in a determinate state? Is interaction free measurement possible? Why does context or history play a role? Is inference observation? Is (even) a single atom, when inside vacuum, truly isolated? Why is quantum-ness lost as systems/environments become complex/stronger? How ‘large’ can qubits be? Do causal and informational isolation coincide in the ‘real’ world? Why don’t we ever observe Tartaric Acid switch its handedness? Is common sense a good guide to how the physical world functions? Would we widely mine quantum entanglement as a ‘resource’? How much weirder will it get? &, would ‘…Quantum-Mechanical Description of Physical Reality Be Considered Complete?’ in the future?  SynTalk thinks about these & more questions using concepts from quantum physics (Prof. Anupam Garg, Northwestern University, Evanston (IL)), philosophy (Dr. Tarun Menon, TISS, Mumbai), & quantum computing (Dr. Rajamani Vijayaraghavan, TIFR, Mumbai).

SynTalk is pleased and privileged to have hosted the following SynTalkrs (in alphabetical order) on its #TIQW show.

Prof. Anupam Garg (quantum physics) is Professor at the Department of Physics & Astronomy, Northwestern University, Evanston (IL), USA. His current research interests are collective magnetization dynamics in molecular nanomagnets, & coherent-state path integrals, especially for spin, and spin semi-classics. His earlier research areas have included, macroscopic quantum phenomena, magnetic particles, macroscopic realism, quantum computing, superconductivity, superfluidity, and quasicrystals. He Garg completed his M.Sc. in Physics from IIT Delhi (1977) and M.S. (Physics, 1981), and  Ph.D. (Physics, 1983) from Cornell University, USA. He held a postdoctoral position at the Institute for Theoretical Physics, University of California, Santa Barbara (1985-1988), and was also the John D. and Catherine T. MacArthur Chair Research Associate, at the University of Illinois at Urbana-Champaign (1983-1985). Prof. Garg has held short term visiting positions at multiple institutes, such as, Niels Bohr Institute (Copenhagen), IISc. (Bangalore), University of Augsberg (Augsberg), Institute for Scientific Interchange (Torino), ICTP (Trieste), and Louis Neel Laboratory, CNRS (Grenoble). His significant scientific contributions include: Leggett–Garg inequality (a mathematical inequality fulfilled by all macrorealistic physical theories), and the Garg-Onuchic-Ambegaokar model (a model of charge transfer, which is extensively used for benchmarking methods aimed at calculating charge transfer rates). He has published a book titled, ‘Classical Electromagnetism in a Nutshell’ (Princeton University Press, 2012). Prof. Garg is an elected Fellow of American Physical Society (APS, 2012).

Dr. Tarun Menon (philosophy) is Assistant Professor, Centre for Science Technology and Society, Tata Institute of Social Sciences (TISS), Mumbai. His research interests are philosophy of physics (statistical mechanics), philosophy of science (confirmation theory), metaphysics (time, causation, probability), political philosophy, epistemology, & philosophy of social science. Dr. Menon completed his B.A. (Physics) from Amherst College (Massachusetts, 2005), and his Ph.D. in Philosophy from University of California, San Diego (2013). Prior to joining TISS, Dr. Menon taught as the Visiting Faculty at the Department of Philosophy, University of Hyderabad (2014). He has delivered invited talks at ICTS (Bangalore, 2018), American University of Beirut (Beirut, 2017), & NYU (Abu Dhabi, 2017). Dr. Menon’s research has been  published in peer-reviewed journals such as, Journal of the National Human Rights Commission, Philosophy of Science, & The Oxford Handbook of the Philosophy of Physics. He has also presented peer-reviewed work at notable conferences, such as, the 9th Annual Climate Change Conference (TISS, 2018), the Philosophy of Hilary Putnam (IIT Bombay, 2015), the American Philosophical Association Pacific Division Meeting (San Diego, 2011), & the Philosophy of Science Association Meeting (Montreal, 2010). Dr. Menon is also the Programme Co-ordinator, M.A./M.Sc. in Climate Change and Sustainability Studies, TISS, and Subject Expert, Board of Studies, Department of Philosophy, Sophia College and Jai Hind College (both in Mumbai).

Dr. Rajamani Vijayaraghavan (quantum computing) is Associate Professor at the Department of Condensed Matter Physics and Materials Science at TIFR (Mumbai) where he also leads The Quantum Measurement and Control Laboratory (QuMac). His research interests are focused on the study of quantum phenomena in superconducting electrical circuits. In particular, he studies measurement in quantum systems and measurement based feedback control to steer and stabilize quantum circuits. He also works on novel qubit circuits, ultra low noise amplification and high frequency signal generation and detection. Dr. Vijayraghavan completed his B.Sc. (Physics) from St. Stephen’s College (1999), B.A. (Natural Sciences) from University of Cambridge (Cambridge, UK, 2001), and Ph.D. (Applied Physics) from Yale University (Connecticut, USA, 2008). As part of his Ph.D. thesis, he developed the Josephson bifurcation amplifier for quantum measurements. He subsequently held a postdoctoral position at the Department of Physics, University of California, Berkeley (2008-2012). His research areas during his postdoctoral work included: low noise, cryogenic microwave amplifiers, microwave magnetometry of molecular magnets, high fidelity quantum measurements for superconducting quantum bits, Quantum feedback and control, and Josephson weak-link junctions for quantum information applications. Dr. Vijayaraghavan has recently received a significant 5 year grant (as co-PI) from the Defense Research & Development Organization (DRDO, India) for the ‘Development of Quantum Computing Architecture with Silicon based Spin Qubit’.
