Top 15 Quantum Computing Startups In 2023

Best Quantum Computing Startups will be discussed in this article. Quantum computing is a rapidly growing domain that strives to solve some of the multiple challenging problems that humanity encounters in the 21st century. IBM estimates that a complex problem would carry a normal supercomputer a week. A quantum computer? 1 second. Quantum computing is even relatively new, getting a call size of around $554.6 billion in 2021. By the end of 2029, it’s launched to be around $4.7 trillion, with a compound increase rate of 31.2%.

Major players like Amazon, IBM, & Microsoft are increasingly concentrating on quantum computing as a potential solution to their most complex interaction puzzles. In particular, Amazon even has its own Amazon Quantum Solutions Lab. Read below for our checklist of the world’s most exciting and ingenious quantum computing startups.
