Scale-up Engineering Program

Building a quantum computer is a major challenge in understanding the quantum effects that we want to put to practical use for computation. Along with that we have a big challenge in designing the control and measurement electronics that are needed to operate a complex device such as a quantum computer at high frequencies and temperatures near absolute zero.

Led by Program Manager Associate Professor Arne Laucht from UNSW Sydney, the Scale-up Engineering Program focuses on developing these enabling technologies: high-sensitivity quantum measurements, control and readout multiplexing for routing information into, out of, and within the quantum processor.
