Quantum technology procurement in Singapore covers three quite separate fields — quantum computing, quantum sensing, and quantum communications — most of it still early-stage and easy to over-buy. Be specific about the outcome you need, insist on evidence rather than roadmap slides, and treat quantum-safe security as a migration plan rather than a hardware purchase.
How to evaluate a quantum technology vendor in Singapore
- Separate the three quantum domains before you engage — quantum computing, quantum sensing, and quantum communications / QKD — because the vendors, maturity, and buyer use cases barely overlap, and confirm the ACRA-registered entity and UEN behind the brand.
- Be clear-eyed about maturity: most quantum computing today is NISQ-era and experimental, so ask for the concrete problem the vendor has actually run, on which hardware or simulator, and what advantage was measured against a classical baseline.
- Pin the access and delivery model — cloud access to third-party hardware, a hybrid classical-quantum workflow, or on-premises equipment — and confirm what your team must operate versus what the vendor runs, plus realistic timelines and milestones.
- For security-driven buyers, treat this as a post-quantum cryptography readiness exercise: ask for a crypto-agility and migration plan aligned to the emerging NIST PQC standards rather than a purchase of unproven hardware.
- Check the Singapore ecosystem and continuity signals — links to the National Quantum Office, A*STAR, or CQT at NUS, available talent, funding support such as EDG, and where any data or results are hosted under PDPA.
Verify for Horizon Quantum Computing
- Confirm key details directly with the vendor — this listing isn't vendor-managed yet.
- Ask for two recent Singapore client references you can speak with.
- Ask for a written scope of services before comparing quotes.
- Request evidence of relevant certifications and their current validity.
Questions to ask
- Which quantum domain — computing, sensing, or communications — does your offering address, and at what maturity?
- What specific problem have you run on real hardware or a simulator, and how did results compare to a classical baseline?
- Is this cloud-accessed, hybrid, or on-premises, and what must our team operate versus what you run?
- If our goal is quantum-safe security, what is your crypto-agility and post-quantum migration plan?
