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…
Strong hole-photon coupling in planar Ge for probing charge degree and strongly-correlated states
Franco De Palma, Fabian Oppliger, Wonjin Jang +7
Semiconductor quantum dots (QDs) in planar germanium (Ge) heterostructures have emerged as front-runners for future hole-based quantum processors. Here, we present strong 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…
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…
