Alice & Bob has officially released the Phase 1 results for France’s PROQCIMA quantum program, marking a significant step forward in the development of fault-tolerant quantum computing. The report highlights several technical achievements that serve as foundational building blocks for scalable quantum systems, specifically focusing on the stability and reliability of qubit operations.
Key technical milestones reported include the successful operation of multi-qubit chips and the execution of noise-biased CNOT gates. These achievements are critical for moving beyond experimental prototypes toward functional systems. Furthermore, the team successfully implemented quantum error correction cycles, a prerequisite for maintaining the integrity of information in a noisy quantum environment.
The PROQCIMA program is designed with an ambitious long-term roadmap, aiming to achieve a milestone of 1,000 logical qubits by 2032. This goal underscores the transition from physical qubits—which are highly susceptible to environmental interference—to logical qubits, which are protected by error-correcting codes.
To support this ambitious trajectory, the program has seen an increase in budget allocation. This investment is intended to accelerate the engineering required to scale the hardware and software infrastructure necessary to meet the 2032 target. The results from Phase 1 provide a validated framework for the subsequent stages of the initiative.
By demonstrating these capabilities, Alice & Bob is positioning its technology as a viable path toward practical, large-scale quantum utility. The successful execution of these early milestones provides a technical blueprint for the high-fidelity operations required for complex quantum algorithms.
