Meet Dr. Ilan Rosen

Advisor: Dr. William Oliver

Institution: Massachusetts Institute of Technology

Bio:  Ilan Rosen received a B.S. in physics from the University of California at Santa Barbara in 2015, and a Ph.D. in Applied Physics from Stanford University in 2021. In his Ph.D. thesis, which was advised by David Goldhaber-Gordon, Ilan studied electrical transport in topological materials, focusing on superconducting contact to 3D topological insulators and chiral transport in quantum anomalous Hall systems. Ilan is now a postdoctoral fellow at the Engineering QUantum Systems (EQuS) group at the Massachusetts Institute of Technology, supervised by William D. Oliver, where he studies superconductor- and semiconductor-based quantum devices.

Abstract:  Superconducting quantum logic has developed at a rapid pace, culminating in demonstrations of high-fidelity single- and multi-qubit gate operations and the implementation of increasingly complex algorithms. Yet the superconducting quantum platform remains limited by qubit coherence times, which are typically tens to hundreds of microseconds. Spin-based quantum information platforms, on the other hand, provide exceptionally long coherence times, but face a number of challenges for scaling. We are working to apply techniques and lessons learned from superconducting qubit operation to the operation of spin-based quantum systems. Our goals include improving spin qubit performance benchmarking and generating long-range entanglement, which will drive applications in spin-based quantum logic, magnetic sensing, and spin-photon transduction.
