Rate My Professor Constantin Schrade

Constantin Schrade serves as an Assistant Professor in the Department of Physics and Astronomy at Louisiana State University, leading the “Theory of Quantum Circuits & Materials” group as Principal Investigator. He earned his Bachelor’s and Master’s degrees in physics from ETH Zurich in Switzerland. He obtained his Ph.D. in theoretical physics from the University of Basel in 2017 under the supervision of Professor Daniel Loss, focusing his dissertation research on spin-based and topological quantum information processing. Following his Ph.D., Dr. Schrade was a postdoctoral researcher from 2017 to 2020 at the Massachusetts Institute of Technology (MIT) in the Department of Physics and Materials Research Laboratory, supervised by Professor Liang Fu and Dr. Jagadeesh Moodera, where he investigated superconducting quantum information devices and novel quantum materials. He then served as Research Assistant Professor in Quantum Information Science and Quantum Condensed Matter Physics at the Niels Bohr Institute in Copenhagen, Denmark, until the end of 2023, as a member of the Center for Quantum Devices (QDev).

In the field of Physics, Dr. Schrade specializes in Quantum Information Science and Condensed Matter Theory, particularly the intersection of superconducting quantum circuits and quantum materials. His research group develops novel superconducting qubits and Josephson devices for applications in quantum information processing and superconducting electronics. Key research topics include voltage-tunable superconducting qubits, high-fidelity quantum gate protocols, quantum-limited parametric amplifiers, Josephson diodes, and triple hybrid materials combining superconductors, ferromagnets, and semiconductors. The group maintains close collaborations with experimental laboratories in the United States and Europe. His influential publications include “Parity conserving Cooper pair transport and ideal superconducting diode in planar Germanium” (Nature Communications 15, 169, 2024, with Marco Valentini et al.), “Josephson diode effect in supercurrent interferometers” (Physical Review Letters 129, 267702, 2022, with Ruben Seoane Souto and Martin Leijnse), “Entangling transmons with low-frequency protected superconducting qubits” (PRX Quantum, 030329, 2022, with Andrea Maiani and Morten Kjaergaard), “Protected hybrid superconducting qubit in an array of gate-tunable Josephson interferometers” (PRX Quantum 3, 030303, 2022, with Charles M. Marcus and András Gyenis), “Quantum Computing with Majorana Kramers Pairs” (Physical Review Letters 129, 227002, 2022, with Liang Fu), “Majorana Superconducting Qubit” (Physical Review Letters 121, 267002, 2018, with Liang Fu), and “Parity-controlled 2π Josephson effect mediated by Majorana Kramers pairs” (Physical Review Letters 120, 267002, 2018, with Liang Fu).
