Quantum Computing Stocks

How to invest in quantum computing.
Here is the list of pure-play quantum computing companies that have US-listed stocks?

Company, Stock ticker, Equity Market Capitalization (Jan 27, 2023)

1. D-Wave Quantum Inc., QBTS, $137M
2. Rigetti, RGTI, $99M
3. Quantum Computing, Inc, QUBT, $95M

There are many other companies that are building their business that are not yet stock market listed in the US, and there are many large companies with nascent quantum computing programs. One company, Honeywell, spun out their quantum computing business with a quantum consultancy.

Over time, we will add those firms and figure out a meaningful way to share their valuations, and to somehow isolate a 'best guess' at their quantum computing and quantum information science business equity market capitalizations.

We will build this page over time.

Disclosure: We own D-Wave Systems common stock warrants because we have been a multi-year user of their quantum annealing systems.
