Professor Robert L. Byer is the William R. Kenan, Jr. Professor of Applied Physics at Stanford University. He has made numerous contributions to laser science and technology including the demonstration of the first tunable visible parametric oscillator, the development of the Q-switched unstable resonator Nd:YAG laser, remote sensing using tunable infrared sources and precision spectroscopy using Coherent Anti Stokes Raman Scattering (CARS). Current research includes the development of nonlinear optical materials and laser diode pumped solid state laser sources for applications to gravitational wave detection and to laser particle acceleration.
I am the Administrative Assistant of the PHI Lab. Prior to this role, I worked as the Program Coordinator for Stanford University’s Shorenstein Asia-Pacific Research Center Japan Program. In addition, I have experience in recruiting as well as finance and operations. I was born in Brazil, but grew up mostly on the East Coast of the US, and I graduated from the University of British Columbia with a bachelor’s degree in Japanese language and culture.

I am interested in the artificial creation of topological, non-Hermitian and strongly-correlated systems in photonic and hybrid light-matter systems. By engineering the structure and interaction in photonic networks, such as time-multiplexed pulse networks and fabricated on-chip non-linear optical circuits, we aim to realize, study and control condensed matter systems such as bosonic fractional quantum Hall effects, fractional Chern insulators and quantum spin liquids.
Senior Research Scientist, Ph.D., Stanford University
I first discovered physics in high school, where I taught myself electromagnetism to build a Tesla coil. During college (B.S. 2010, Caltech) I studied theoretical particle physics and general relativity. Since graduate school (Ph.D. 2016, Stanford), I have pursued research in quantum control, quantum optics, nonlinear optics. My current work focuses on the emerging nexus of photonics, deep learning, quantum computing, and optimization.
My research field is theory and first-principle/approximated simulation of models of dissipative nonlinear optics (particularly, lasers and optical parametric oscillators), which have quantum characteristics, for example, squeezing, sub/super-Poissonian statistics, and entanglement. I’m willing to simulate models of condensed-matter physics with coupled lasers, known as dissipative counterpart of equilibrium phase transition models.
Research Scientist, Ph.D., Stanford University
I study the intersection of nonlinear dynamics with optical systems, particularly nanophotonic devices. My work with NTT PHI Lab addresses the following questions: What are the ultimate limits, in terms of size and energy requirements, of nonlinear photonic devices? What dynamical regimes are still undiscovered? How can these nonlinear devices and processes be used to enable new technologies, such quantum and classical light sources?
Senior Research Scientist, Ph.D., University of Tokyo
I am a Senior Research Scientist of the PHI Lab. I received my undergraduate/master’s degrees in electronic engineering from the University of Electro-Communications in 1996/1998. I received my Doctor of Engineering from the University of Tokyo in 2006. I was working on the experimental investigation of optical properties of solid-sate nano-structures. My current research interests are focused on the potential capability and application of coherent network computing.
I am the Program Manager of the PHI Lab. Prior to joining the PHI Lab, I was the program coordinator for the Japan Program at the Shorenstein Asia-Pacific Research Center at Stanford University. My areas of expertise include Program Operation, Project and Financial Management, and Event Planning. I was born in Japan and lived in China, Oman, Pakistan, France, and Russia before coming to the U.S.
Research Scientist, Ph.D., Stanford University
I am broadly interested in both quantum optics and computing. Thus, at NTT-PHI labs, I am expanding the current toolbox of quantum optics and investigating if employing them improves our ability to perform interesting computation. More concretely, I am currently studying the generation of non-classical (non-Gaussian) states of light in on-chip photonic architectures and am examining the implications of this work for the coherent Ising machine.
Senior Research Scientist, Ph.D., UC Santa Barbara
I study decoherence and the quantum-classical transition. I am especially interested in defining and efficiently identifying wavefunction “branches” in out-of-equilibrium many-body systems. These quasi-classical components can be characterized by the presence of spatially disjoint redundant information, and classically sampling from them may speed up real-time tensor-network simulations. In the past, I have studied the sensitivity of massive superpositions to very small momentum transfers, especially as a way to use matter interferometers to detect MeV-scale dark matter.
My main area of research relates to the development of on-chip optical sources and their application to precision measurements. In particular, my work has focused on understanding nonlinear or quantum optics in high-quality-factor microresonators, and utilizing them to develop narrow linewidth lasers, chip-scale optical frequency combs, and optical sensors. In the PHI Lab, I am interested in exploring topological photonics and quantum optics for computation and information science.
I am a research operations manager at PHI Lab. My main focus has been on the applications of physics and new technologies to solve real-world problems. Before joining here, I was a research assistant at the Harvard seismology group working on the hypocenter-relocation of earthquakes to obtain insights on seismic activities. I had worked at various labs, a gas company, and in science media.
Senior Research Scientist, Ph.D., Harvard University
I’m a theorist fascinated by questions at the interface of physics, neuroscience, and machine learning. My guiding questions include: What can deep learning models tell us about computational mechanisms of the brain? What is the learning algorithm governing our brain? How are these mechanisms realized respecting the laws of physics? At PHI Lab, I will further aim to harness scientific discoveries to design more natural intelligent algorithms and hardware.
My work with NTT PHI lab touches the topics of complexity, intelligence, nonlinearity, lasers, and quantum optics. I am focused on the following questions. In what sense do natural complex systems perform computations? Can we use this perspective of natural computation to design and discover intelligent machines or algorithms, to understand the brain, or to utilize quantum resources? Can viewing nature as computation help uncover universal physical principles?
