Quantum computing is one of the hottest trends on Wall Street. Once limited to theoretical physics and government labs, it’s now capturing the imagination of investors. Big companies like IBM (IBM), Google (GOOGL), and Microsoft (MSFT) are pushing the boundaries. At the same time, smaller players such as Rigetti (RGTI) and IonQ (IONQ) have ridden the quantum hype to become notable names among investors. However, as you read this, less-known start-ups are also progressing. These start-ups are securing massive funding and attracting venture capitalists. While they aren’t publicly traded yet, their rapid growth suggests IPOs might be coming soon.

Here are three promising quantum start-ups to watch.
PsiQuantum: The Photonic Quantum Computing Pioneer
Founded in 2016, PsiQuantum aims to build a large-scale, fault-tolerant quantum computer using silicon photonics. Unlike traditional superconducting qubits, PsiQuantum’s photonic approach allows for greater scalability and compatibility with existing semiconductor manufacturing. This unique method has attracted over $665 million from investors like BlackRock (BLK), Baillie Gifford, and Microsoft’s M12 venture fund.
PsiQuantum also received a $940 million investment from the Australian government to speed up the development of a commercially viable quantum machine by 2027. The company is focused on developing a million-qubit system to solve complex real-world problems. While PsiQuantum hasn’t announced an IPO yet, its strong backing and ambitious plans suggest it could go public in the next few years.
QuEra Computing: Advancing Neutral-Atom Quantum Tech
Boston-based QuEra Computing is making a name for itself with neutral-atom quantum technology. This method arranges atoms in 3D arrays controlled by lasers, offering better scalability and fewer errors. Unlike superconducting qubits, which need extreme cooling, QuEra’s approach allows for easier error correction and long-term stability.
QuEra recently raised over $230 million from investors like Google’s Quantum AI unit and SoftBank Vision Fund (SFTBY). This funding will help advance fault-tolerant quantum computing, a key step toward commercial viability. While QuEra hasn’t announced IPO plans, its rapid progress and strong funding will likely make a public debut in the next few years.
Multiverse Computing: The Quantum Software Leader
Spain-based Multiverse Computing focuses on making quantum technology accessible through software. Founded in 2019, Multiverse specializes in quantum algorithms for finance, energy, and manufacturing. Its flagship platform, Singularity, allows users to apply quantum solutions without extensive technical knowledge. Even Excel users can integrate quantum-powered optimizations.
Multiverse recently secured €25 million in funding, bringing its valuation to about €100 million. Its partnerships with financial institutions, like the Bank of Canada, show its real-world applications in risk analysis and portfolio optimization. While Multiverse hasn’t outlined IPO plans, its strong position in quantum software suggests a public offering could be in the future as demand grows.
