Robust Interlayer-Coherent Quantum Hall States in Twisted Bilayer Graphene
Dohun Kim, Byungmin Kang, Yong-Bin Choi +5
We introduce a novel two-dimensional electronic system with ultrastrong interlayer interactions, namely twisted bilayer graphene with a large twist angle, as an ideal ground for re…
Defect Passivation of 2D Semiconductors by Fixating Chemisorbed Oxygen Molecules via h-BN Encapsulations
Jin-Woo Jung, Hyeon-Seo Choi, Young-Jun Lee +9
Hexagonal boron nitride (h-BN) is a key ingredient for various two-dimensional (2D) van der Waals heterostructure devices, but the exact role of h-BN encapsulation in relation to t…
Wigner-molecularization-enabled dynamic nuclear field programming
Wonjin Jang, Jehyun Kim, Jaemin Park +8
Multielectron semiconductor quantum dots (QDs) provide a novel platform to study the role of Coulomb correlations in finite quantum systems and their impact on many-body energy spe…
Probing two-qubit capacitive interactions beyond bilinear regime using dual Hamiltonian parameter estimations
Jonginn Yun, Jaemin Park, Hyeongyu Jang +8
We report the simultaneous operation and two-qubit coupling measurement of a pair of two-electron spin qubits that are actively decoupled from quasistatic nuclear noise in a GaAs q…
Approaching ideal visibility in singlet-triplet qubit operations using energy-selective tunneling-based Hamiltonian estimation
Jehyun Kim, Jonginn Yun, Wonjin Jang +9
We report energy selective tunneling readout-based Hamiltonian parameter estimation of a two-electron spin qubit in a GaAs quantum dot array. Optimization of readout fidelity enabl…
