Spectroscopy of low-lying valley states in hot Si/SiGe quantum dots
Connor Nasseraddin, Heun Mo Yoo, Tanner M. Janda +1
The paper compares pulsed‑gate spectroscopy and detuning‑axis spectroscopy for measuring low‑lying valley states in Si/SiGe quantum dots, showing that detuning‑axis spectroscopy ac…
Co-optimization of spin coherence and valley splitting in Si/SiGe heterostructures
Peihong Zhang, Xuedong Hu, Saif Ullah +1
Single electron spins can be used to encode and process information in semiconductor quantum devices. Progress has been hindered by materials challenges, such as the small energy s…
Directly visualizing the energy level structure of quantum dot molecules
Heun Mo Yoo, Tanner M. Janda, Connor Nasseraddin +1
The orbital, spin and valley degrees of freedom in silicon quantum dots support many modes of spin qubit operation. However, it is generally challenging to obtain information about…
Microwave response of electrically driven spins in a three-qubit quantum processor
Tanner M. Janda, Heun Mo Yoo, Connor Nasseraddin +3
In electric dipole spin resonance (EDSR), a single spin is electrically driven in the field gradient produced by a micromagnet. While EDSR has enabled high fidelity gate operations…
Leakage-protected idle operation of a triangular exchange-only spin qubit
Joseph D. Broz, Jesse C. Hoke, Edwin Acuna +1
We characterize the coherence of a triangular exchange-only (EO) spin qubit operated at a leakage-protected idle (LPI) point. The triangular geometry enables independent control of…
Spin qubit shuttling between coupled quantum dots with inhomogeneous Landé g-tensors
Zhi-Hai Liu, Xiao-Fei Liu, H. Q. Xu
By utilizing the site-dependent spin quantization axis in semiconductor quantum dot (QD) arrays, shuttling-based spin qubit gates have become an appealing approach to realize scala…
