Roadmap Target
Triple Alpha early access launched on Ember-1 in Q2 2026; full-stack enterprise quantum application platform 2026–2027
Horizon Quantum is a software infrastructure company. Triple Alpha IDE + Helium compiler language synthesize quantum circuits from classical C/Python code without requiring quantum expertise. In-house quantum computer Ember-1 (inaugurated Jan 2026): Rigetti Novera QPU (9-qubit superconducting, ~99.4% 2Q fidelity, Maybell cryostat + Quantum Machines OPX1000 control) — first quantum software company to own and operate a quantum computer, and Singapore's first commercially deployed system. Strategic agreement with IonQ (2026) to add a 256-qubit trapped-ion system for a multi-modality testbed. Strategic collaboration with AQT (April 2026) integrates Triple Alpha with AQT's trapped-ion processors. Ember-1 opened to select first users through Triple Alpha in Q2 2026.
⚠ Q2 filing backfill
Horizon Quantum's FY2025 20-F is not usefully XBRL-tagged, so its reported revenue and net loss remain manually backfilled. Cash, debt, equity, and trailing operating cash flow are updated from its Q2 2026 results on Form 6-K; newer valid SEC facts replace these dated values.
