We have learned how to rotate an electron spin state using external magnetic fields. We have been assuming that the electron floats in space. In reality, it will interact with matters and we need to decide how to set the electron in place. We will use an electron in silicon and illustrate how to achieve the five DiVincenzo’s criteria mentioned in Sect. 1.3. In this chapter, we will discuss silicon spin qubit initialization and readout (measurement). In the next chapter, we will discuss the implementation of 1-qubit and 2-qubit gates.

摘要

We have learned how to rotate an electron spin state using external magnetic fields. We have been assuming that the electron floats in space. In reality, it will interact with matters and we need to decide how to set the electron in place. We will use an electron in silicon and illustrate how to achieve the five DiVincenzo’s criteria mentioned in Sect. 1.3. In this chapter, we will discuss silicon spin qubit initialization and readout (measurement). In the next chapter, we will discuss the implementation of 1-qubit and 2-qubit gates.
