In this article, we will discuss the 11 Best Quantum Computing Stocks to Invest In Right Now

According to McKinsey, when it comes to quantum technology (QT), the investment continues to surge and breakthroughs continue to multiply. The 3 core pillars of QT, i.e., quantum computing, quantum communication, and quantum sensing, can together garner up to $97 billion in revenue worldwide by 2035. McKinsey is seeing a transition from development to deployment.

Key Trends Impacting the Industry

While the QT start-up ecosystem remains a fertile ground for breakthroughs, McKinsey highlighted that well-established tech giants fueled the bulk of change in 2024. Some of the advancements from renowned companies consist of suppression of error rates relative to the number of qubits, development of multiple high-fidelity qubits, and significant reductions in the cost of quantum error correction.

McKinsey also opines that the total quantum communication market size was pegged at $1.2 billion in 2024, which is expected to reach $10.5 billion – $14.9 billion by 2035. Its research demonstrates that governments are presently the largest purchasers of quantum communication technologies, at ~57% of all purchases in 2024, while the private sector continues to increasingly adopt the technology.

By 2035, McKinsey believes that the telecommunications sector is anticipated to account for 16% – 26% of the overall spending on quantum communication products.

Amidst such favourable trends, let us now have a look at the 11 Best Quantum Computing Stocks to Invest In Right Now.
