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…
Single-shot readout of a driven hybrid qubit in a GaAs double quantum dot
Wonjin Jang, Min-Kyun Cho, Hyeongyu Jang +7
We report a single-shot-based projective readout of a semiconductor hybrid qubit formed by three electrons in a GaAs double quantum dot. Voltage-controlled adiabatic transitions be…
Robust energy selective tunneling readout of singlet triplet qubits under large magnetic field gradient
Wonjin Jang, Jehyun Kim, Min-Kyun Cho +6
Fast and high-fidelity quantum state detection is essential for building robust spin-based quantum information processing platforms in semiconductors. The Pauli spin blockade (PSB)…
