Terahertz magneto-nanoscopy of encapsulated monolayer graphene

Richard H. J. Kim, Sunwoong Yang, Taehoon Kim +7

This study investigates the nanoscale conductivity of encapsulated monolayer graphene at temperatures down to 5 K and magnetic fields of up to 1 T. We use the scattering-type scann…

Vortex-Controlled Quasiparticle Multiplication and Self-Growth Dynamics in Superconducting Resonators

Joong M. Park, Martin Mootz, Richard H. J. Kim +11

Even in the quantum limit, non-equilibrium quasiparticle (QP) populations induce QP poisoning that irreversibly relaxes the quantum state and significantly degrades the coherence o…

Visualizing heterogeneous dipole fields by terahertz light coupling in individual nano-junctions used in transmon qubits

R. H. J. Kim, J. M. Park, S. Haeuser +12

The fundamental challenge underlying superconducting quantum computing is to characterize heterogeneity and disorder in the underlying quantum circuits. These nonuniform distributi…
