Technical paper

University of New South Wales researchers have shown how a quantum computer can be manufactured using mostly standard silicon technology.

Indeed, research teams all over the world are exploring different ways to design a working computing chip that can integrate quantum interactions. Now, these UNSW engineers believe they have cracked the problem, reimagining the silicon microprocessors we know to create a complete design for a quantum computer chip that can be manufactured using mostly standard industry processes and components.

The quantum chip design has a novel architecture that allows quantum calculations to be performed using existing CMOS semiconductor components, and was devised by Andrew Dzurak, director of the Australian National Fabrication Facility at the University of New South Wales (UNSW), and Menno Veldhorst, lead author of the paper who was a research fellow at UNSW when the conceptual work was done.



David Stoddard says:

Quantum computers are just a matter of time. We already have quantum computers, but when we truly have fully qualified quantum computers with enough cubits, it will revolutionize computing.

We should be educating people to program quantum computers. We should research how to use quantum computers on problems that are not trivial “quantum computer problems”. I really find it odd how little we are preparing compared to how quantum leap of computational evolution it provides.

Just by being able to solve Traveling Salesman Problem will change everything. Well, to “solve” will never happen, but in practice large portion of problems that can be transformed to TSP could be solved fast enough.
