Spin-valley qubit dynamics in exchange-coupled silicon quantum dots

HIGHLIGHTS

• who: Buterakos Donovan from the DepartmentUniversity of Park, Maryland, USA have published the research: Spin-Valley Qubit Dynamics in Exchange-Coupled Silicon Quantum Dots, in the Journal: (JOURNAL) of 23/Dec/2021
• what: The authors show that if the valley splitting is large and electrons are not properly initialized to valley eigenstates then the time evolution of the system will lead to spin-valley entanglement. The authors show that for small valley splitting spin-valley entanglement does not affect the measurement probabilities of two-qubit systems; however systems with more qubits will be affected.
