How do I Invest in Quantum Computing?
Pure-play quantum computing companies that you can invest in right now

While large firms like IBM, Honeywell and Google are developing quantum computing systems, buying their stock offers at most a tiny fraction of a percent in quantum computing exposure. Most other companies developing quantum technology are start-ups and private, making it difficult for the average investor to participate. However, there are five pure-play quantum computing companies that are publicly listed and available to anyone with a brokerage account. From largest to smallest, they are:

Growth of Quantum Programming
Qiskit, developed by IBM, was one of the first platforms available to program quantum computers. Interest in the open-source SDK has grown steadily since it was introduced, and this tracks growth in quantum computing as a whole.
