6 Transforming Caltech Quantum Science Pre-historic: Feynman, Thorne, Pre-millennial: Preskill (1983), Vahala (1986), Kimble (1989), Yeh (1989), Eisenstein (1996) Theory: Schulman (2000), Kitaev (2002), Refael (2005), Motrunich (2006), Y. Chen (2007), Alicea (2012), X. Chen (2014), Vidick (2014), Brandão (2016) Experiment: Painter (2002), Adhikari (2006), Schwab (2009), Hsieh (2012), Faraon (2012), Rosenbaum (2014), Nadj-Perge (2016), Endres (2016)

7 How the IQIM Happened : Institute for Quantum Information (IQI) 2010: Center for Exotic Quantum Systems (CEQS) 2011: NSF Physics Frontiers Center 53 pre-proposals, 17 full proposals, 11 reverse site visits. 4 centers renewed, 1 new center funded (us). 5 years, $12.6M + $5M from Moore Foundation

8 Four Major Activities MA1: Quantum Information Preskill, X. Chen, Kitaev, Refael, Schulman, Vidick, Brandão MA2: Quantum Condensed Matter Refael, Alicea, X. Chen, Kitaev, Fisher, Motrunich Eisenstein, Hsieh, Yeh, Nadj-Perge, Endres, Rosenbaum MA3: Quantum Optics Kimble, Faraon, Painter, Vahala, Endres MA4: Mechanical Quantum Systems Painter, Adhikari, Y. Chen, Schwab, Vahala

12 What s Coming? NSF 5-year on-site review, early 2016 Renewal pre-proposal July 2016 Full proposal January 2017 Reverse Site Visit May 2017 Next funding cycle would begin fall 2017 Other PFCs competing for renewal: Center for Ultracold Atoms (CUA) JILA PFC Kavli Institute for Cosmological Physics (KICP) Kavli Institute for Theoretical Physics (KITP) Institute for Quantum Information and Matter (IQIM)

13 Some things we proposed MA1: Quantum Information Algorithms for QFT. Simulating thermal systems. Majoranafermions in wires. Protected SC circuits. Classification of quantum phases. MA2: Quantum Condensed Matter Transport and polarization in nu = 5/2 QH state. Bilayer nonabelian states. Disorder in topological insulators. Out of equilibrium, Floquet. Graphene. Fractionalization. Environment engineering. MA3: Quantum Optics Quantum networks as many-body systems. Coupled cavity arrays. 1D photon-mediated entanglement. Optically trapped resonators. MA4: Mechanical Quantum Systems Quantum optomechanical circuits. Optomechanical nonlinearity. Ultralow dissipation. Optical suspension. Superfluid resonators. Human-size objects.

14 Quantum Supremacy

15 Diversity

16 Diversity Women in physics in US: ~20%, very slow upward trend. A broad problem, but IQIM can provide leadership. Critical mass is essential. No silver bullet, requires patience. (Don t give up!) Aggressive recruiting. Outreach, blogging, social media Seminars: pay attention to Diversity. Support for families (maternity/paternity, childcare policy, ). Harassment. Get feedback.

17 Mentoring

18 Mentoring Annual student/postdoc reviews. Second research supervisor? Encourage Outreach participation. Postdoc/Student Lunches, other social events? Caltech Postdoctoral Association. Life After Caltech Seminar Series? Careers outside research universities. Industry day. Respect that students/postdocs are already plenty busy!

19 Outreach

20 If you can explain what you do to a 6th grader you can explain it to a Congressman. Eric Cornell

21 Fundraising

22 Research

23 Let s hear your ideas! Grand Challenges / Reachable Goals

24 Some quantum science grand challenges -- SPT phases and real materials. -- Gapless phases. -- Experimental signatures of topological phases. -- Ephemeral phases / stroboscopic imaging. -- Classical applications of quantum materials. -- Experimental systems with strong long-range interactions. -- Testing quantum mechanics. -- Experimental explorations of quantum measurement. -- Better methods for (classically) simulating 2D and 3D strongly correlated systems. -- Quantum memories with very long storage times. -- Thermalization, MBL, foundations of quantum stat. mech. -- Entanglement area law. -- Emergent geometry and quantum entanglement.
