QuamCore, an Israeli deep-tech startup focused on quantum computing, has raised US$26 million in series A funding to develop its quantum processor architecture.

The round was led by Sentinel Global, with participation from Arkin Capital, Viola Ventures, Earth & Beyond Ventures, Surround Ventures, Rhodium, and Quantum Leap.

The total also includes a US$4 million grant from the Israel Innovation Authority, bringing QuamCore’s total funding to US$35 million.

The company is working on an architecture to scale superconducting quantum systems up to 1 million qubits within a single cryostat, far beyond the current limit of around 5,000 qubits per module.

It plans to use the funds to move from simulation to processor fabrication, establish a quantum lab, and grow its team.

QuamCore is led by CEO Alon Cohen, CTO Prof. Shay Hacohen-Gourgy, and chief scientist Prof. Serge Rosenblum.

🧠 Food for thought

1️⃣ Industry leaders face a massive scaling gap to reach practical quantum advantage

QuamCore’s million-qubit target represents a dramatic leap beyond current industry capabilities, highlighting just how far quantum computing still needs to advance.

Today’s quantum computing leaders like Google and IBM max out at around 5,000 qubits per cryogenic module, while IBM has set an ambitious goal to reach 100,000 qubits by 2033 and Google aims for 1 million qubits by 2029 1.

This means QuamCore is competing directly with tech giants’ long-term roadmaps, attempting to achieve in the near term what established players project will take years to accomplish.

The gap becomes even more striking when considering that experts estimate useful quantum computers need between 1,000 to 100,000 qubits to solve real-world problems 2.

Even the lower end of this range remains challenging. IBM’s most advanced processors reached just 433 qubits with their Osprey system in 2022 1.

2️⃣ Thermal management represents quantum computing’s most persistent bottleneck

QuamCore’s focus on eliminating heavy cabling addresses a fundamental physics problem that has constrained quantum systems since their inception.
