Coherent and ultra-low-power EDSR with a flopping-mode spin qubit in germanium
Alexei Orekhov, Wonjin Jang, Pan Zhang +13
Hole spin qubits in semiconductor quantum dots (QDs) enable high-fidelity all-electric control, but conventional electric dipole spin resonance (EDSR) can require substantial rf dr…
True decoherence-free-subspace derived from a semiconductor double quantum dot Heisenberg spin-trimer
Wonjin Jang, Jehyun Kim, Jaemin Park +6
Spins in solid systems can inherently serve as qubits for quantum simulation or quantum information processing. Spin qubits are usually prone to environmental magnetic field fluctu…
Coherence of a field-gradient-driven singlet-triplet qubit coupled to many-electron spin states in 28Si/SiGe
Younguk Song, Jonginn Yun, Jehyun Kim +9
Engineered spin-electric coupling enables spin qubits in semiconductor nanostructures to be manipulated efficiently and addressed individually. While synthetic spin-orbit coupling…
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…
Three individual two-axis control of singlet-triplet qubits in a micromagnet integrated quantum dot array
Wonjin Jang, Min-Kyun Cho, Jehyun Kim +3
We report individual confinement and two-axis qubit operations of two electron spin qubits in GaAs gate-defined sextuple quantum dot array with integrated micro-magnet. As a first…
Fast raster scan multiplexed charge stability measurements toward high-throughput quantum dot array calibration
Wonjin Jang, Min-Kyun Cho, Myungwon Lee +6
We report raster scan multiplexed charge-stability diagram measurements for tuning multiple gate-defined quantum dots in GaAs/AlGaAs heterostructures. We evaluate the charge sensit…
