Analysis
This paper explores a novel approach to manipulate the valley degree of freedom in silicon-based qubits, which is crucial for improving their performance. It challenges the conventional understanding of valley splitting and introduces the concept of "valleyors" to describe the valley degree of freedom. The paper identifies potential mechanisms for creating valley-magnetic fields, which could be used to control the valley degree of freedom using external fields like strain and magnetic fields. This work offers new insights into the control of valley qubits and suggests alternative methods beyond existing techniques.
