How many companies are building Quantum Compters?

As of March 2024 there are around 80 campanies working on building Quantum Computers

Although funding declined in the U.S. by 80% it still seems to us that companies contine to grow every year.

Quantim insider is keeping up with all the companies and their updates you can see here.

This number grows every year.

Investments dropped in 2023

A 50% drop occurred in venture capital invested into quantum startups from $2.2 billion in 2022 to around $1.2 billion in 2023 globally

Europe, the Middle East and Africa grew by 3%

The United States saw an 80% decline

APAC region declined by 17%

Over 30 governments have committed to more than $40 billion in public funding commitments to quantum technologies which will be deployed in the next 10 years.

Of these governments actively involved in quantum technologies, over 20 have formulated coordinated policies, funding, and roadmaps.

National labs and quantum computing centres have accelerated practical applications with dedicated quantum computing centres and hubs emerging.

Annual government funding commitments to quantum represent an estimated 2x the quantum VC investment peak in 2022.
