Alice & Bob Demonstrates New Approach to Stabilizing Cat With DC Voltage Bias
Alice & Bob, with the École Normale Supérieure de Lyon, demonstrated a DC-voltage-bias method for stabilising superconducting cat qubits. The technique is reported to be faster than prior approaches and to enable more compact designs that generate less heat. Cat qubits encode information in microwave resonators, and the work is aimed at fault-tolerant superconducting hardware.

This could allow Alice & Bob to pack more cat qubits into a single dilution refrigerator within two years because lower heat dissipation per qubit eases the cooling budget that currently constrains superconducting scaling.
If the DC-bias stabilisation can be integrated with existing fabrication processes, the reduced thermal load and smaller footprint per qubit would raise the number of qubits that can be operated in a given cryogenic system without exceeding its cooling capacity. Alice & Bob is already commercialising cat-qubit hardware, so the path to engineering integration is credible.
