A qubit for use in an adiabatic quantum annealing (computing, AQC) approach comprising a first quantum dot and a second quantum dot forming a double quantum dot which acts as a qubit, a third quantum dot and a fourth quantum dot forming a second double quantum dot which is capacitively coupled to the qubit double dot thereby being used as a variable capacitance to adjust the capacitance of qubit double dot, a first control element for adjusting the capacitance of the second kind of double dot, a second control element for supplying a control voltage to the first kind of double quantum dot, a metallic or superconducting contact capacitively coupling the fourth quantum dot, and an electric charge sensor for providing an indication of the state of the qubit double dot. |
