10 Best Quantum Computing Stocks to Buy for 2026

In this article, we will discuss the 10 Best Quantum Computing Stocks to Buy for 2026.

Sylvia Jablonski, CEO, CIO & Co-Founder of Defiance ETFs, recently appeared on CNBC Television and highlighted that the investing public is now witnessing real-world use cases of quantum computing. She noted the promising trial, in which HSBC, while working with IBM, leveraged an approach combining quantum and classical computing resources to deliver up to a 34% improvement in predicting the likelihood that a trade will be filled at a quoted price as compared to the common classical techniques used in the industry.

This legitimizes quantum computing, added Jablonski, while explaining that quantum computing is at a stage where AI was about 5-10 years ago. Discussing the upcoming use cases, Jablonski believes that JPMorgan, City, and Goldman Sachs may be the next names that will enter this space. According to her, numerous growth opportunities are available in the banking sector.

Quantum computing also affects many other sectors, including pharmaceuticals, cryptography, aerospace, and defense. She noted that the global government invested ~$40 billion in quantum computing. Jablonski, while quoting McKinsey, highlighted the revenue growth expectations from ~$4 billion to ~$70 billion over the next decade or so.

If AI has helped process data, quantum computing is expected to help optimize that data and make decisions from it, added Jablonski.

Amidst such trends, we will now have a look at the 10 Best Quantum Computing Stocks to Buy for 2026.
