High-fidelity EDSR in Si/SiGe Wiggle Wells
Hudaiba Soomro, Minyoung Kim, Avani Vivrekar +3
Si/SiGe quantum wells that incorporate Ge concentration oscillations, known as long-period Wiggle Wells, have been shown to enhance the Dresselhaus spin-orbit coupling of conductio…
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…
Omnidirectional shuttling to avoid valley excitations in Si/SiGe quantum wells
Róbert Németh, Vatsal K. Bandaru, Pedro Alves +7
Conveyor-mode shuttling is a key approach for implementing intermediate-range coupling between electron-spin qubits in quantum dots. Initial implementations are encouraging; howeve…
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…
The quantum Zeno and anti-Zeno effects in the strong coupling regime
Ghazi Khan, Hudaiba Soomro, Muhammad Usman Baig +2
It is well known that repeated projective measurements can either speed up (the Zeno effect) or slow down (the anti-Zeno effect) quantum evolution. Until now, however, studies of t…
Transforming spin chains with a continuous driving field
Hudaiba Soomro, Adam Zaman Chaudhry
A continuous, sinusoidal control field is used to suitably transform quantum spin chains. In particular, we are able to transform the quantum Ising chain to the quantum XY model, a…
