Fabricating qubits using advanced semiconductor manufacturing processes

Posted by in categories: computing, quantum physics

Quantum computers are promising computing machines that perform computations leveraging the collective properties of quantum physics states. These computers could help to tackle many computational problems that are currently intractable with conventional computers.

Despite their promise, fabricating quantum computers on a large-scale is currently very challenging, as a full-scale quantum computer integrates millions of qubits. To ensure that they can be produced using industrial semiconductor manufacturing processes, quantum device engineers have been trying to create quantum computers based on silicon quantum dots.

Nonetheless, existing quantum computers have been primarily fabricated using and conventional lift-off processes. This greatly limits their production rates, as both these processes only yield a few properly functioning devices at a time.
