Statistical characterization of valley coupling in Si/SiGe quantum dots via -factor measurements near a valley vortex
Benjamin D. Woods, Merritt P. Losert, Nasir R. Elston +5
The presence of low-energy valley excitations in Si/SiGe heterostructures often causes spin qubits to fail. It is therefore important to develop robust protocols for characterizing…
Warm Start Adaptive-Bias Quantum Approximate Optimization Algorithm
Yunlong Yu, Xiang-Bin Wang, Nic Shannon +1
In the search for quantum advantage in real--world problems, one promising avenue is to use a quantum algorithm to improve on the solution found using an efficient classical algori…
g-factor theory of Si/SiGe quantum dots: spin-valley and giant renormalization effects
Benjamin D. Woods, Merritt P. Losert, Robert Joynt +1
Understanding the -factor physics of Si/SiGe quantum dots is crucial for realizing high-quality spin qubits. While previous work has explained some aspects of -factor physics…
Using stochastic resonance of two-level systems to increase qubit decoherence times
Yujun Choi, S. N. Coppersmith, Robert Joynt
Two-level systems (TLS) are the major source of dephasing of spin qubits in numerous quantum computing platforms. In spite of much effort, it has been difficult to substantially mi…
Exploiting many-body localization for scalable variational quantum simulation
Chenfeng Cao, Yeqing Zhou, Swamit Tannu +2
Variational quantum algorithms (VQAs) represent a promising pathway toward achieving practical quantum advantage on near-term hardware. Despite this promise, for generic, expressiv…
Coupling conduction-band valleys in SiGe heterostructures via shear strain and Ge concentration oscillations
Benjamin D. Woods, Hudaiba Soomro, E. S. Joseph +4
Engineering conduction-band valley couplings is a key challenge for Si-based spin qubits. Recent work has shown that the most reliable method for enhancing valley couplings entails…
