[QuamCore](https://www.quamcore.com/), an Israeli [deep tech](https://www.startuphub.ai/ai-news/startup-news/2025/landmark-swiss-deep-tech-report-2025-spotlights-switzerlands-rise-as-a-global-leader-in-deep-tech-driving-100b-in-startup-value/) startup, secured $26 million in Series A funding. Sentinel Global led the round. This investment aims to develop a one-million-qubit [quantum computing](https://www.startuphub.ai/ai-news/funding-round/2025/zuriq-eth-zurich-spinoff-raised-4-2m-to-be-the-nvidia-of-quantum-computing/) system. Consequently, total funding for the company now stands at $35 million.

## Advancing Quantum Scalability

QuamCore's innovation focuses on scaling superconducting qubits. Current advanced systems, such as those from [Google](https://www.startuphub.ai/ai-news/ai-video/2025/google-unveils-agentic-stack-to-tame-ai-development-chaos/) and [IBM](https://www.startuphub.ai/ai-news/ai-video/2025/ais-hidden-peril-ibm-reveals-pervasive-security-gaps/), typically support around 5,000 qubits per cryostat. QuamCore has designed an architecture capable of scaling to one million qubits within a single cryostat. This approach significantly reduces the need for extensive multi-cryostat infrastructure.

Furthermore, the company integrates superconducting digital control logic directly into the cryostat. This integration minimizes cabling and eliminates thermal bottlenecks. The design also incorporates built-in error correction for fault-tolerant operation.

The company will move from design to fabrication of its first-generation processors. It will also establish a dedicated quantum lab and scale operations.

Arkin Capital participated in the Series A round. Existing investors Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium, and Quantum Leap also contributed. Additionally, the Israel Innovation Authority provided a $4 million non-dilutive grant. QuamCore, founded in 2022, is based in Herzliya, Israel. This funding accelerates chip production and prototype integration.
