Beside the advances that quantum computers promise to deliver in chemistry, materials science, pharmaceutics and other domains, being considered a disruptive technology, they can potentially transform the economic landscape of the countries that develop them.
In this project, a structured simulation procedure for semiconducting qubits, that can be generalized and easily re-used, was created. This is the first time such a venture is completed on this scale, and also resulted in solving a riddle over what mostly defines the voltage at which the onset of electron transport inside Quantum Point Contacts (components of the electron flying qubits technology) takes place. With multiple comparisons between simulation with experiment, strong evidence was given over the physics that defines the operation of the devices.
For the field of electron flying qubits, the simulations can be proven essential in the development of the former as a mature technology, with competitive error rates, that in some cases may surpass the equivalent CMOS spin qubit. The models can also be expanded in order to simulate not only other semiconducting technologies, but also hybrid semiconducting/superconducting structures.
These results have the potential to establish the simulation procedure followed in the Quantum Engineering domain, which can aid in the faster development of semiconducting quantum technologies in the lab. They are already being undertaken by the collaborating experimental group and will soon be available to other groups worldwide. The most essential gain through this project is the reduction in the time and resources spent in the lab to find functioning and optimum designs for devices. They can aid in testing new theories for qubit devices, as well as scaling up those already existing.
