Quantum computing startups are seeing more investment; according to McKinsey, investors poured nearly $2 billion into quantum startups worldwide, which marked a 50% increase compared to the $1.3 billion they received in 2023. A rise in funding has created a healthy ecosystem that allows these startups to innovate and scale, increasing the breakthroughs we are seeing in the quantum space.

To mark these leaps in the industry, we have compiled a list of some of the top quantum computing startups in the industry right now.

Algorithmiq

Algorithmiq is a Helsinki-based quantum startup that is developing quantum algorithm software to accelerate life sciences research. The company aims to leverage quantum software so that new drugs are able to be discovered, invented, and brought to market quickly and cost-effectively, leading to more precise medical treatments and a paradigm shift in drug discovery and development.

Algorithmiq creates quantum algorithms that combine classical and quantum computing to simulate complex molecular systems at atomistic resolution, targeting problems inaccessible to traditional computation. It has also developed a proprietary framework, informationally complete error‑mitigation methods (specifically Tensor‑Network Error Mitigation, TEM), to reduce noise on near‑term quantum devices, enabling deeper, more accurate simulations without additional quantum hardware cost.

Alice & Bob

Alice & Bob is a quantum computing company founded in Paris, whose goal is to create the first universal, fault-tolerant quantum computer. The startup specialises in cat qubits, a proprietary technology design of superconducting qubits with built‑in hardware error correction. These cat qubits suppress certain quantum faults natively, substantially reducing the total number of qubits required. It claims to cut hardware demands up to two hundred-fold compared to other platforms.

In May 2025, Alice & Bob announced it was investing €40 million into building a new quantum lab near Paris. It will be one of the most advanced QPU (Quantum Processing Unit) development facilities in Europe, and will enable the startup to develop its next series of quantum chips: Lithium, Beryllium, and Graphene. Graphene is the 100-logic qubit quantum computer that Alice & Bob is planning on bringing to market in 2030.

IQM Quantum Computers

IQM is quickly becoming a global leader in building quantum computers. It builds on-premises quantum computers for supercomputing centres, enterprises, and research labs. The startup also offers access to the power of quantum computing via its cloud offering, IQM Resonance.

In May 2025, IQM signed an agreement with VTT Technical Research Centre in Finland to deliver a 150-qubit and a 300-qubit quantum computer, to be delivered in 2026 and 2027. This builds on its previous delivery of 5-qubit, 20-qubit, and 50-qubit quantum computers to VTT.

Moth

Moth was founded with the idea of bringing quantum computing directly into the hands of artists. The startup was founded in 2022, and is broadening the scope of quantum computing by focusing its use cases on the creative industries.

It does this by developing quantum algorithms to enhance the use of generative AI in the creative industries. Starting with music, the startup also plans on expanding into gaming, and further arts; not to replace the artist, but enhance the art experience.

Moth’s debut products include a suite of quantum music production tools, such as a synthesiser, a generative music model, and audio-processing technology, all of which, for the first time, place quantum computing directly in the hands of creatives. Moth has already gained traction among artists, including the musician ILĀ, who has been experimenting with the technology to create a continuous stream of music based on her own data. This has lead to ILĀ’s ‘Infinite Mix’, which is currently livestreaming, and able to be listened to in real-time.

Orca Computing

Orca Computing develops full-stack photonic quantum computing systems, both hardware and software, which aims to unlock near‑term industrial use cases in machine learning and optimisation. It is also pursuing error‑corrected general‑purpose quantum systems in the longer term. Orca Computing was founded in 2019 as a spin-out of the University of Oxford.

Orca’s flagship product line, the PT Series, uses programmable boson sampling via single photons in optical fibre rather than silicon‑based systems. This fibre‑interconnected, rack‑mounted architecture enables air‑cooled operation at room temperature and avoids the need for cryogenic cooling, reducing the cost and improving scalability.
