      quantum physicist | entrepreneur

      Hello! I am a physicist and entrepreneur working in the US. I co-founded Polygence, which is an online research academy focused on providing personalized research projects to high school students.


      Previously, I was an Associate at the Department of Physics at Harvard University and obtained my PhD in theoretical quantum physics from MIT in the fall of 2018. My work focused on creating robust nanoscale systems to enable quantum information processing. Most of my thesis was completed while working under the supervision of Prof. Mikhail Lukin at Harvard University.

       

      I completed the Mathematical Tripos (Part III) at Cambridge University, obtaining an MA.St in 2012. Prior to that, I completed a B.Sc. at the University of St Andrews in Logic, Philosophy of Science and Physics. My undergraduate research focused on the optical theory of invisibility under the supervision of Prof. Ulf Leonhardt.

       

      I was born and raised in Budapest, Hungary, where I was fortunate to learn from outstanding high school teachers, including Mr. Botond Molnár and Ms. Erika Pálfiné Kovács.

      Topological Quantum Optics Using an Atom-Photonic Crystal Interface

      J Perczel, J Borregaard, DE Chang, SF Yelin, MD Lukin
      Physical Review Letters 124, 083603 (2020)

      In this work, we proposed a novel nanophotonic platform that creates strong interactions between atomic bits (qubits) and visible-frequency photons and gives rise to robust photonic states that are extremely resistant to imperfections, such as missing qubits and noise. Such states are important for creating topological quantum computers.

      Theory of dipole radiation near a Dirac photonic crystal

      J Perczel, MD Lukin

      Physical Review A 101 (3), 033822 (2020)

      In this paper, we developed a mathematical and computational framework to describe the light emitted by a single atom near a nanophotonic structure with a so-called Dirac cone spectrum. Such photonic structures are actively explored for building large-scale quantum networks,

      Quantum Optics in Maxwell's Fish Eye Lens with Single Atoms and Photons

      J Perczel, P Kómar, MD Lukin

      Physical Review A 98, 033803 (2018)

      In this work, we resolved a long-standing controversy regarding the focusing abilities of an optical lens, called Maxwell's Fish Eye. We showed that the lens cannot focus photons to an area whose diameter is smaller than the wavelength of light. We also demonstrated that this lens can create 'entanglement' (the most valuable quantum resource) between atoms.

      Photonic Band Structure of Two-dimensional Atomic Lattices

      Janos Perczel, Johannes Borregaard, Darrick E Chang, Hannes Pichler, Susanne F Yelin, Peter Zoller, Mikhail D Lukin

      Physical Review A 96, 063801 (2017)

      In this project, we showed that that 2D atomic lattices suspended in free space using lasers can trap visible-frequency photons and guide them around in lossless circular orbits even in the presence of significant imperfections.

      Topological quantum optics in two-dimensional atomic arrays

      Janos Perczel, Johannes Borregaard, Darrick E Chang, Hannes Pichler, Susanne F Yelin, Peter Zoller, Mikhail D Lukin

      Physical Review Letters 119, 023603 (2017)

      In this paper, we borrowed ideas from an abstract branch of mathematics, called topology, to design an atomic system, where photons can travel around the edges of an atomic system with little to no sensitivity to imperfections and missing atoms.

      Visible-frequency hyperbolic metasurface

      Alexander A High, Robert C Devlin, Alan Dibos, Mark Polking, Dominik S Wild, Janos Perczel, Nathalie P de Leon, Mikhail D Lukin, Hongkun Park

      Nature 522, 192 (2015)

      In this experimental project we showed that a non-sized silver grating can exhibit the so called spin-orbit coupling of light, which has important applications in quantum information processing. 

      Invisibility cloaking without superluminal propagation

      Janos Perczel, Tomáš Tyc and Ulf Leonhardt

      New Journal of Physics 13, 083007 (2011)

      In this paper, we provided the theoretical blueprint for an invisibility cloak that can make objects invisible regardless of their color. Previous proposals for invisibility cloaks were all functional only at a single frequency (i.e. single color).  

      Partial transmutation of singularities in optical instruments

      Janos Perczel, Carlos Garcia-Meca and Ulf Leonhardt

      Journal of Optics 13, 075103 (2011)

      In this work we showed that the invisible sphere (an invisible optical lens) can be implemented with physical parameters that require very careful engineering only in a limited region of the lens (near the center of the sphere).  

      From Fermat's principle to invisibility

      Janos Perczel and Ulf Leonhardt

      Procedia Computer Science 7, 216-220 (2011)

      In this project, we showed how Non-Euclidean geometry can be used to design a system that can hide objects from sight without requiring extreme material parameters for implementation.
