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…
Temperature selective thermometry with sub-microsecond time resolution using dressed-spin states in diamond
Jiwon Yun, Kiho Kim, Sungjoon Park +1
Versatile nanoscale sensors that are susceptible to changes in a variety of physical quantities often exhibit limited selectivity. This paper reports a novel scheme based on microw…
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…
Deep learning enhanced individual nuclear-spin detection
Kyunghoon Jung, M. H. Abobeih, Jiwon Yun +5
The detection of nuclear spins using individual electron spins has enabled new opportunities in quantum sensing and quantum information processing. Proof-of-principle experiments h…
Algorithmic decomposition for efficient multiple nuclear spin detection in diamond
Hyunseok Oh, Jiwon Yun, M. H. Abobeih +4
Efficiently detecting and characterizing individual spins in solid-state hosts is an essential step to expand the fields of quantum sensing and quantum information processing. Whil…
