Qubits aren’t a league table.
Hardware quality, speed and the task matter alongside scale. Look for demonstrated results and distinguish physical from logical qubits.

Explore by quantum exposure
Business activity, not investment merit.How we classify quantum exposure
QubitWire assigns one primary category from documented company activity. Categories can overlap; a computing or security classification does not mean the whole business is quantum. Read each company’s business context and original sources.
- Quantum computing
- Businesses focused on quantum computers, quantum software and photonic computing.
- Diversified technology
- Large businesses with quantum programs. Their shares reflect substantial activity beyond quantum.
- Enabling technology
- Chips, fabrication, photonics and instruments that support quantum systems.
- Quantum security
- Quantum communication, cryptography and post-quantum security. These are different from building quantum computers.

A BETTER RESEARCH HABIT
Three things a stock chart won’t tell you.
A milestone isn’t a business model.
Ask what customers pay for, whether orders become revenue and how much cash the business needs to keep developing.
Read the company filingsA quantum connection has many forms.
A specialist, a chip supplier and a diversified technology company can have very different economics. Compare the business before the price.

How companies are selected
This curated directory includes publicly listed operating businesses with documented quantum computing, enabling technology or quantum security activity. It uses one listing per company and four exposure categories. Category membership is editorial classification, not a stock ranking. Private companies and ETFs are outside this company directory.
How to read the financials
Compare revenue, cash use, funding needs and dilution alongside the company’s own filings. Provider financials refer to the whole listed company. Recent listings may include predecessor or SPAC periods and have limited history. Research questions on this page are prompts for investigation, not claims of current performance.
