Quantum error correction can constantly recalibrate a processor
Google researchers have developed a method to use error correction data to continuously recalibrate quantum processors in real-time. This breakthrough addresses the issue of hardware drift, which previously required pausing calculations for manual calibration.
Why it matters
Continuous calibration is a critical step toward making quantum computers stable enough to perform long, complex, and useful calculations.

Issues like whether we can make enough high-quality hardware qubits to connect into the error-corrected logical qubits we need, and how we generate the states needed to perform universal computation on those logical qubits. But there are also many less prominent challenges that will need to be solved before we can perform calculations.
