Auto-tuning qubits using AI

Scientists at the National Institute of Standards and Technology (NIST) has proposed that the best way to tune qubits is using an AI.

The team outlines a way to teach an AI to make an interconnected set of adjustments to tiny quantum dots, which are among the many promising devices for creating the qubits that would form the switches in a quantum computer’s processor.

Precisely tweaking the dots is crucial for transforming them into properly functioning qubits, and until now the job had to be done painstakingly by human operators, requiring hours of work to create even a small handful of qubits for a single calculation. Especially because a practical quantum computer with many interacting qubits would require far more dots—and adjustments—than a human could manage.

The team’s paper has been published in the journal Physical Review Applied.
