Tuning and Operation of Quantum Dots and Related Apparatus
Spin qubits in quantum dots are promising candidates towards quantum computation. However, a considerable amount of technical development is still necessary before the advent of a quantum computer. For quantum dots, this involves independently controlling and sweeping the voltages of a multitude of electrostatic gates and monitoring several charge sensing signals. Thus, a fast measurement device with a high number of inputs and outputs is critical for the efficiency of the development of multiple quantum dot devices. The group of Michel Pioro-Ladrière at Institut Quantique, Université de Sherbrooke, Canada, have recently conducted measurements on quantum dots and related components using the Nanonis Tramea instrument, which will be discussed in this application note.
