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…
Identifying Materials-Level Sources of Performance Variation in Superconducting Transmon Qubits
Akshay A. Murthy, Mustafa Bal, Michael J. Bedzyk +46
The Superconducting Materials and Systems (SQMS) Center, a DOE National Quantum Information Science Research Center, has conducted a comprehensive and coordinated study using super…
Polarization rotation in a ferroelectric BaTiO film through low-energy He-implantation
Andreas Herklotz, Robert Roth, Zhi Xiang Chong +6
Domain engineering in ferroelectric thin films is crucial for next-generation microelectronic and photonic technologies. Here, a method is demonstrated to precisely control domain…
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…
