Scientists removed major obstacles in making quantum computers a reality

Quantum engineers from UNSW Sydney have removed a decades-old major hurdle: how to reliably control millions of qubits in a silicon quantum computer chip? They come up with a new method that can efficiently control millions of spin qubits.

Spin-based silicon quantum electronic circuits offer a scalable platform for quantum computation. Scientists added their newly developed component called a crystal prism called a dielectric resonator.
