Horizon Quantum Computing and Alice & Bob have announced a strategic collaboration to integrate their respective software and hardware capabilities, aimed at accelerating the deployment of fault‑tolerant quantum computing (FTQC). The partnership centers on the integration of Alice & Bob’s quantum emulators—“virtual versions” of their physical hardware—into Horizon Quantum’s Triple Alpha development environment. This full‑stack solution is designed to allow developers to experiment with and test quantum error correction (QEC) protocols using Alice & Bob’s specialized “cat qubit” architecture before physical systems are fully deployed.

Alice & Bob’s cat qubit technology is specifically engineered for high hardware efficiency, with the company recently demonstrating that its architecture could reduce the physical qubit overhead for large‑scale systems by up to 200 times compared to standard approaches. By making these emulated systems available through the Triple Alpha platform, Horizon Quantum is broadening its hardware‑agnostic compiler to support this promising new architecture. The collaboration also brings Triple Alpha’s resource analysis tools to Alice & Bob’s backends, enabling developers to track critical metrics such as qubit count and gate depth to optimize algorithm performance across different levels of abstraction.

Strategically, this collaboration positions Horizon Quantum’s software stack as a primary compilation pipeline for Alice & Bob’s forthcoming quantum processing units (QPUs). The news follows Horizon Quantum’s recent milestone of becoming the first software‑centric firm to own and operate its own in‑house quantum computer at its Singapore headquarters. Furthermore, Horizon Quantum is currently progressing toward a public listing on the Nasdaq via a business combination with dMY Squared Technology Group, Inc., a transaction supported by a $110 million PIPE investment that includes participation from major industry players like IonQ.
