Series of seven interview sessions with Carver Mead, Gordon and Betty Moore Professor Emeritus at Caltech. Mead recounts his childhood in California, and he describes the impact of watching his father’s career in the electric power industry. He credits his schoolteachers for encouraging his early interests in math and science, and he explains why attending Caltech as an undergraduate was an easy choice for him because he felt immediately welcomed during his first visit. He describes what it was like to learn quantum mechanics from Linus Pauling, and he explains that his decision to major in electrical engineering stemmed from the fact that applied physics was shunned in the physics department because Murray Gell-Mann referred to it as “squalid state physics.” Mead describes his decision to stay at Caltech for graduate school, and he explains how he became interested in semiconductors and transistors and what would become the origins of “device physics” and how his dissertation research contributed to these developments. He describes his developing understanding that the future of electronics would be in low power, high-performance devices and why he would be best positioned to foster this future as a faculty member at Caltech. Mead describes his collaborations and interest in industry labs including IBM, RCA, and Bell, and he describes his initial and then longtime work with Gordon Moore. He discusses the value of RF transmitters in 1960s-era communications technology and the prospects of satellite telecommunications at the dawn of the space age. Mead describes the origins of VSLI technology, word processors, and microcomputers, and he describes his collaboration with Lynn Conway and the process that went into the classic textbook they coauthored. He describes his research using the human mind as a source of inspiration to push electronics and microprocessors to the next level, and he explains the value of bouncing ideas off of Feynman over lunch. Mead describes the singular potential of his student and collaborator Misha Mahowald, and the value of his work with Arnold Beckman. He discusses the several companies that were spun out of his research in electronics and biophysics, and he describes his work on cameras with Michihiro Yamaki and the learning curve associated with research culture in Japan. Mead offers his perspective on the need to update the debates between Einstein and Bohr in the wake of recent developments in physics, and he explains the intellectual origins of his text Collective Electrodynamics. He explains why scientific debates can take on philosophical or even religious dynamics, and he discusses the origins of G4V and how to think of gravitational attraction as an analogy to electromagnetic interaction. Relatedly, Mead describes his work with Kip Thorne and his involvement with the LIGO endeavor, and he explains why the line between science and engineering is fuzzier than is commonly understood. He explains the significance of the Shapiro Delay, he surmises that the mystery of Dark Energy is sourced in the fact that physics is approaching the problem in the wrong way, and he explains why physics has become hamstrung in its pursuit of mathematizing physical reality ahead of experimental guidance. Mead explains that his views are rooted in his ability to think in pictures, as opposed to abstract symbols, and that the field needs to be more welcoming and inclusive to those who may see math as a barrier to working in physics at a high level. At the end of the interview, Mead describes his interest in current challenges with electric grid infrastructure, he explains why he has championed the work of women in science throughout his career, and he strikes an optimistic note that science always has and will continue, to provide solutions to the world’s most pressing problems.

Interview with John Preskill, Richard P. Feynman Professor of Theoretical Physics at Caltech, and Director of the Institute for Quantum Information and Matter at Caltech. Preskill describes the origins of IQIM as a research pivot from the initial excitement in the 1970s to move beyond Standard Model physics and to understand the origin of electroweak symmetry breaking. He emphasizes the importance of Shor’s algorithm and the significance of bringing Alexei Kitaev into the project. Preskill discusses the support he secured from the NSF and DARPA, and he recounts his childhood in Chicago and his captivation with the Space Race. He describes his undergraduate experience at Princeton and his relationship with Arthur Wightman and John Wheeler. Preskill explains his decision to pursue his thesis research at Harvard with the intention of working with Sidney Coleman, and he explains the circumstances that led to Steve Weinberg becoming his advisor. He discusses the earliest days of particle theorists applying their research to cosmological inquiry, his collaboration with Michael Peskin, and his interest in the connection of topology with particle physics. Preskill describes his research on magnetic monopoles, and the relevance of condensed matter theory for his interests. He explains the opportunities that led to his appointment to the Harvard Society of Fellows and his eventual faculty appointment at Harvard, his thesis work on technicolor, and the excitement surrounding inflation in the early 1980s. Preskill discusses the opportunities that led to his tenure at Caltech and why he started to think seriously about quantum information and questions relating to thermodynamic costs to computing. He explains the meaning of black hole information, the ideas at the foundation of Quantum Supremacy, and he narrates the famous story of the Thorne, Hawking, and Preskill bets. Preskill describes the advances in quantum research which compelled him to add “matter” to the original IQI project which was originally a purely theoretical endeavor. He discusses the fact that end uses for true quantum computing remain open questions, and he surveys IQIM’s developments over the past decade and the strategic partnerships he has pursued across academia, industry, and at the National Labs. Preskill surveys the potential value of quantum computing to help solve major cosmological mysteries, and why his recent students are captivated by machine learning. At the end of the interview, Preskill reflects on his intersecting interests and conveys optimism for future progress in understanding quantum gravity from laboratory experiments using quantum simulators and quantum gravity.

Interview with Christopher Monroe, Gilhuly Family Distinguished Presidential Professor of Physics and Electrical Computer Engineering at Duke University. Monroe discusses his ongoing affiliation with the University of Maryland, and his position as chief scientist and co-founder of IonQ. He discusses the competition to achieve true quantum computing, and what it will look like without yet knowing what the applications will be. Monroe discusses his childhood in suburban Detroit and his decision to go to MIT for college, where he focused on systems engineering and electronic circuits. He explains his decision to pursue atomic physics at the University of Colorado to work under the direction of Carl Wieman on collecting cold atoms from a vapor cell, which he describes as a “zig zag” path to Bose condensation. Monroe discusses his postdoctoral research at NIST where he learned ion trap techniques from Dave Wineland and where he worked with Eric Cornell. He explains how he became interested in quantum computing from this research and why quantum computing’s gestation period is stretching into its third decade. Monroe explains his decision to join the faculty at the University of Michigan, where he focused on pulsed lasers for quantum control of atoms. He describes his interest to transfer to UMD partly to be closer to federal entities that were supporting quantum research and to become involved in the Joint Quantum Institute. Monroe explains the value of quantum computing to encryption and intelligence work, he describes the “architecture” of quantum computing, and he narrates the origins of IonQ and the nature of venture capitalism. He discusses China’s role in advancing quantum computing, and he describes preparations for IonQ to go public in the summer of 2021. At the end of the interview, Monroe discusses the focus of the Duke Quantum Center, and he asserts that no matter how impressive quantum computing can become, computer simulation can never replace observation of the natural world.

In this interview, Steven Koonin, University Professor at New York University, recounts his childhood in Brooklyn and his education at Stuyvesant High School, which he credits for providing an excellent education in math and science.
