# List of 41 Quantum Computing Stocks and Public Companies

Below I show a list of public quantum computing companies and stocks that anyone with a brokerage account can invest in in 2022. It is quite amazing how much is already out there. The pure QC plays are few as of now, but still - they are growing.

Pure QC plays in the US (Nasdaq/NYSE):

Ticker Company
ARQQ Arqit
IONQ IonQ
QUBT Quantum Computing Inc
HON Honeywell
RGTI Rigetti

Note that this is mostly hardware - QC software companies are still mostly private, since they are still up and coming.

The following shows the usual suspects. While their core business is something else, these companies all invest into QC. Of course, leading tech stocks, semiconductors, but also military defense companies such as Lockheed:

Ticker Company
GOOG Google
AMZN Amazon
