Theory of spin qubits and the path to scalability
Z. M. McIntyre, Abhikbrata Sarkar, Daniel Loss
Spin qubits have emerged as a leading platform for quantum information processing due to their long coherence times, small footprint, and compatibility with the existing semiconduc…

Micromagnet-free operation of electron spin qubits in Si/SiGe vertical double quantum dots
Abhikbrata Sarkar, Daniel Loss
We study a vertical double quantum dot (DQD) in a Si/SiGe/Si double-well heterostructure for full electrical control of electron Loss-DiVincenzo (LD) spin qubits, using…

Effect of disorder and strain on the operation of planar Ge hole spin qubits
Abhikbrata Sarkar, Pratik Chowdhury, Xuedong Hu +5
Germanium quantum dots in strained heterostructures exhibit fast and coherent hole qubit control in experiments. In this work, we theoretic…
