Hello guys, I want to know how to make sigle or two hole spin qubit quantum gate in Laboratory using germaniuim. We have only sputtering machine to deposit materials, but dont have any lithography technique to make confined regions (quantum dots). I have no clue to start that process. I can make Germanium wafers in our lab as a substrate. can you please suggest a method to do that?

Trivalent elements shall be used as dopant in the germanium for the pupose of hole type Qbits. But you need advanced methods to have it done, to handle with single bits,
