QuamCore

Superconducting Founded 2022 Tel Aviv, Israel

Overview

Claims a fully designed and simulated architecture for scaling superconducting quantum systems to one million qubits in a single cryostat — far beyond the ~5,000-qubit per-module limit of current approaches.

Funding: Series A — $35M raised (led by Sentinel Global, Viola Ventures, Arkin Capital). $4M Israel Innovation Authority grant.

Key Milestones

  • 2022: Founded by CEO Alon Cohen and CTO Professor Shay Hacohen-Gourgy
  • 2025: Raised $26M Series A
  • 2025: Published million-qubit-in-single-cryostat architecture design

Technology Approach

QuamCore claims to have designed an architecture that can scale superconducting quantum systems to one million qubits in a single cryostat — a bold claim given that current approaches hit practical limits around 5,000 qubits per cooling module.

The details of their scaling architecture are not fully public. If validated, it would fundamentally change assumptions about the physical limits of superconducting quantum systems and potentially make the surface code approach to error correction practical at scale.

CEO Alon Cohen previously led radar groups at Mobileye, bringing systems engineering experience from a different deep-tech domain.

Competitive Position

Strengths: If the architecture works, it solves a fundamental scaling problem. Strong Israeli VC backing and government support.

Challenges: Architecture is designed and simulated, not demonstrated. Bold claims without public hardware results require healthy scepticism. Competing against IBM and Google who have decades of superconducting hardware experience.
