Why quantum, why now
The next platform shift
Every ~15 years computing reinvents itself — mainframe → PC → mobile → cloud → AI. Quantum is the next foundational layer, and infrastructure winners compound for decades.
Physics-limited moat
Quantum hardware requires physics PhDs, cryogenics, and billions of R&D. Unlike SaaS, this is not something a two-person startup can replicate in a weekend.
Real customers, real revenue
JPMorgan, BMW, Airbus, Roche and every major national lab already pay for quantum access. Revenue is small but real — and doubling annually.
The advantage window is opening
Chemistry, materials, optimization and cryptanalysis have concrete near-term problems where quantum credibly beats classical. First-mover advantage is real.
Every public route into quantum
Quantum Computing Inc
Photonic quantum + software
Room-temperature photonic chips, entropy sensing
Arqit Quantum
Quantum-safe encryption
Symmetric key infrastructure for the post-quantum era
The startups worth watching for IPOs
You can't buy these yet — but they define the competitive landscape. Several are credible IPO candidates in the next 24 months.
Oxford Quantum Circuits
UK superconducting · Coaxmon architecture
The risks nobody puts in the pitch deck
Timeline uncertainty
Useful quantum advantage may take 5 or 15 years. Names can languish or run 10x on a single announcement.
Extreme volatility
Pure-plays regularly move ±30% in a week. Position size accordingly — this is venture-style risk in a public wrapper.
Winner concentration
Only 2–3 hardware modalities will likely dominate. Betting on the wrong architecture is the single biggest risk.
Dilution & cash burn
Most pure-plays are unprofitable and raise capital annually. Watch share count and runway as closely as tech milestones.
An illustrative quantum portfolio
A conservative sketch, not a recommendation. Balances upside on pure-play winners with the stability of profitable diversified names.
Diversified giants
IBM, GOOGL, MSFT, NVDA — quantum optionality inside profitable businesses.
Quantum ETF
QTUM or QTFF — instant diversification across the whole stack.
Pure-play basket
Split across IONQ, RGTI, QBTS to hedge the hardware-modality bet.
Post-quantum crypto
ARQQ and cybersecurity names positioned for the PQC migration.
Understand what you're investing in — before you invest.
The best quantum investors know the difference between a qubit and a quantum gate, and can tell which milestone actually moves a stock. Start with the fundamentals.
