- Alphabet’s Google Quantum AI has achieved two major quantum computing milestones, including quantum supremacy in 2019 and the introduction of a logical qubit prototype in 2023. The company is a leader in AI, cloud, and mobile technologies, with a goal to build a large quantum computer supporting at least 1 million qubits.
- Microsoft has developed a unique quantum processing approach using topological superconductors. The company introduced the Majorana 1 quantum chip in 2025, aiming to fit over 1 million qubits on a single chip. Microsoft’s topoconductor technology could make it a major winner in the quantum computing industry.
- IonQ, with a market cap of $18 billion, uses trapped-ion architecture for quantum computing. The company’s technology aims to reduce errors, increase qubit interaction, and enhance qubit coherence. IonQ is also developing quantum networking, sensing, and security solutions, positioning itself as a significant player in quantum technology.
