Could future quantum computers be made from simple CMOS transistors on SOI? In any case, this is what the recent work of an INAC-Leti team suggests. In these computers, let us specify it, the unit of information will not be a bit of value 0 or 1 but a quantum bit or qubit which is a superposition of 0 and 1. It remains to find the adequate physical medium to carry out these qubits . Researchers have shown that electron holes (quasi-particles of charge and movement opposite to the electron) confined in transistor channels could play this role. Their intrinsic magnetic moment, or spin state, is very sensitive to gate voltage, making it possible to imagine future electrically controlled spin qubits.
