Outline of Final Research Achievements |
We have developed a methodology and fundamental technology for interface control using localized hydrogens in silicon isotope thin films that implement silicon-based qubits. We have succeeded in developing an efficient condition search method by process measurement of hydrogen incorporation and desorption, highly sensitive detection and precise evaluation of hydrogen cluster defects with isotope engineering, and an apparatus capable of room-temperature evaluation of electrical noise originating from device interface. We also verified the qubit performance of valley separation using isotopically engineered silicon thin films as quantum platforms.
