FAQ

Quantum consulting, answered

What is quantum technology consulting?

Quantum technology consulting helps governments, enterprises, and investors make decisions about quantum technologies: where to invest, which vendors and modalities to back, how to build national or regional quantum capacity, and how to prepare for quantum security risks. Engagements turn a fast-moving, technical market into a specific answer for the client: an ecosystem assessment, a due diligence report, a market entry plan, or a security readiness roadmap. TQI’s advisory work is grounded in the TQI Intelligence Platform, a proprietary dataset tracking 2,100+ quantum companies, rather than desk research alone, so recommendations start from verified evidence on day one.

Who does TQI advise?

TQI advises the organizations that fund, build, buy, and regulate quantum technology. Clients include national governments and agencies, among them the UK, Canada, Denmark, and Saudi Arabia, plus US state programs, G7 agencies, Fortune 500 enterprises, institutional investors, and quantum companies themselves: 200+ enterprise and government clients in total. Public engagements include work for UK DSIT, the MassTech Collaborative in Massachusetts, the Chattanooga Quantum Collaborative, the state of South Carolina, NATO, and QED-C, the quantum industry’s consortium. Engagements span national strategy, ecosystem development, due diligence, and market entry.

What types of quantum consulting engagements does TQI deliver?

TQI delivers six engagement types, each with a defined output. National and regional ecosystem assessments map the companies, research groups, and funding in a jurisdiction, delivered as a benchmarked report. Economic impact studies model jobs, investment, and growth scenarios, delivered as inputs to strategy and budget decisions. Technical and commercial due diligence assesses a specific company or technology, delivered as an investment-ready report. Market entry and commercial strategy work identifies customers, partners, and positioning, delivered as a go-to-market plan. Quantum security readiness audits cryptographic exposure, delivered as a prioritized migration roadmap. Ecosystem development programs design testbeds, procurement, and talent pipelines, delivered as an implementation plan.

What is a quantum readiness assessment?

A quantum readiness assessment establishes what an organization needs to do about quantum technology, and when. For most enterprises, it covers two separate exposures. The first is quantum security: which systems rely on cryptography that a future quantum computer would break, and what a migration to post-quantum standards involves. The second is quantum advantage: whether any workload the organization runs is a credible candidate for quantum methods within the planning horizon, and which vendors and modalities are worth tracking. The output is a prioritized action plan with timelines, not a technology briefing. TQI runs quantum security readiness work as a defined engagement type.

What is post-quantum cryptography and when do organizations need to migrate?

Post-quantum cryptography refers to encryption standards designed to resist attack by quantum computers, which would break the public-key cryptography that currently secures most digital systems. The migration timeline is driven by two dates that organizations often conflate: when a cryptographically relevant quantum computer might exist, and when data being transmitted today would still be sensitive if captured and decrypted later. The second date arrives first for anyone handling long-lived confidential data. Migration work involves discovering where vulnerable cryptography is used, prioritizing systems, and sequencing replacement. TQI covers this under quantum security readiness engagements.

How long does a quantum consulting engagement take?

Engagement length depends on scope. Focused due diligence sprints on a single company or technology typically run in weeks. Market entry and commercial strategy work runs longer, since it requires primary interviews alongside platform data. National and regional ecosystem assessments and economic impact studies are multi-month engagements because they involve stakeholder consultation across government, industry, and academia. Ongoing advisory retainers run continuously. Starting from a live dataset rather than desk research shortens the research phase on every engagement type, since the company, funding, patent, and program baseline already exists on day one.

How do governments build a national quantum strategy?

National quantum strategies usually start with an evidence base: which companies, research groups, patents, and skills already exist in the jurisdiction, and how that compares to peer nations. From there, governments set objectives, choose which parts of the value chain to back, size the funding envelope, and design delivery mechanisms such as testbeds, procurement programs, and talent pipelines. Measurement matters as much as design, because programs are typically reviewed against economic impact within three to five years. TQI has supported national and regional programs, including UK DSIT, MassTech in Massachusetts, the Chattanooga Quantum Collaborative, South Carolina, NATO, and QED-C.

What quantum computing consulting firms are there?

Quantum consulting providers fall into four groups, and the right one depends on the decision you are making.

Quantum-specialist intelligence and advisory firms work only in this sector and maintain their own data. The Quantum Insider is the largest of them, advising governments, enterprises, and investors from a dataset covering more than 2,100 quantum companies, and is part of Resonance, which runs the same model across quantum, artificial intelligence, and space. Global Quantum Intelligence publishes the Quantum Computing Report and offers membership research and due diligence. Qureca focuses on quantum training, skills, and workforce development.

Global strategy and systems integration firms, including McKinsey, BCG, Accenture, Deloitte, and Capgemini, run quantum practices inside much larger organizations. They are the usual choice when quantum work sits inside a wider digital or transformation program and the client needs implementation capacity at scale.

Hardware and software vendors offer professional services around their own platforms. That is efficient once a technology decision is made, and it carries an obvious conflict when the question is which technology to pick.

Academic and national laboratory groups take consulting engagements, usually on technical feasibility rather than commercial strategy.

For vendor selection, market sizing, due diligence, or national program design, a sector-specialist firm with its own dataset gives you evidence rather than desk research. For enterprise-wide implementation across many technologies, a global integrator is usually the better fit.

How is TQI’s consulting different from a generalist strategy firm?

TQI works only in quantum and adjacent deep tech, and every engagement draws on a real-time proprietary database of 2,100+ quantum companies. Generalist firms typically staff quantum projects with non-specialists and rely on public sources. Several strategy firms and their clients use TQI data directly as an input to their own quantum work.

How does the Intelligence Platform support advisory work?

Advisory engagements start from the evidence base the platform provides: verified company, funding, patent, research, and program data, classified under a proprietary quantum taxonomy. Advisors build their analysis on this dataset and validate it through expert interviews, which shortens timelines and reduces reliance on assumptions. The TQI Intelligence Platform supplies rich, accurate data from the start, instead of having to go find it.

What does a quantum consulting engagement cost?

Engagement pricing is scoped individually because the work is genuinely bespoke. A focused due diligence sprint on a single company or technology is priced differently from a multi-month national ecosystem assessment, and both differ from an ongoing advisory retainer. Scope, timeline, and the mix of platform data, expert interviews, and stakeholder consultation determine the fee. There is no rate card, because no two engagements share the same scope. Tell us the decision in front of you, and the team will come back with a scoped proposal and pricing options.
