Scaling Quantum: How QuamCore is Solving Quantum's Scalability Problem

Company & Team Introduction

QuamCore is an Israel-based deep-tech startup, founded in 2022, emerged from stealth mode in early 2025 with a singular focus: to solve the most critical and persistent challenge in quantum computing—scalability.

The company's founding team represents a rare and strategically crucial combination of deep expertise in quantum physics, superconducting device fabrication, and, most importantly, large-scale semiconductor systems architecture :

• Alon Cohen (Co-Founder & CEO): A seasoned technology leader from Mobileye, an Intel company and a world leader in advanced driver-assistance systems. At Mobileye, Cohen was a chief architect and head of the EyeC Radar algorithm group, a core technology for autonomous vehicle perception. He holds over 40 patents in complex fields like radar, communication, and signal processing and is a recipient of Intel's highest innovation honor. His background provides QuamCore with critical systems architecture and commercial productization experience.

• Prof. Shay Hacohen-Gourgy (Co-Founder & CTO): A leading academic expert in the field of superconducting quantum computing from the Technion – Israel Institute of Technology, with over 15 years of pioneering experimental research experience in quantum information and solid-state physics.

• Prof. Serge Rosenblum (Co-Founder & Chief Scientist): A leading researcher from the Weizmann Institute of Science, bringing over 15 years of experience across a variety of quantum technologies and a track record of breakthrough publications in top-tier scientific journals.

Product Overview

QuamCore is addressing the central challenge of quantum computing: scalability. Today's most advanced quantum processors, like those from Google and IBM, are limited to only a few thousand qubits. This isn't because we can't fabricate more qubits, but because each one requires its own individual wires running from room-temperature electronics down into the super-cold cryostat. This creates a "cable crisis" that makes scaling to a million qubits physically and thermally impossible.

QuamCore's breakthrough is a new architectural design that solves this problem by moving the control electronics directly inside the cryostat, right next to the quantum processor. This patented approach eliminates the need for millions of external cables and the overwhelming heat load they would generate, paving the way for a single, compact, million-qubit machine. QuamCore’s innovation is based on three core principles:

• Integrated Architecture: Instead of using external cables for each qubit, QuamCore's design integrates ultra-low-power superconducting control logic directly within the cryogenic environment. This radically reduces the number of external connections needed by a factor of over 1,000.

• Eliminating the Bottleneck: By removing the vast network of cables, QuamCore bypasses the primary physical and thermal barrier that has historically prevented the scaling of superconducting quantum computers.

• Built-in Error Correction: The architecture is designed from the ground up to include built-in error correction, a critical feature for building a fault-tolerant quantum computer capable of solving practical problems.

QuamCore’s approach is not just an incremental improvement; it's a fundamental architectural shift.

Market Opportunity

The ultimate market for quantum computing lies in solving problems that are intractable for even the most powerful classical supercomputers. These practical, high-value applications—in fields such as drug discovery, materials science, financial modeling, logistics optimization, and artificial intelligence—will require large-scale, fault-tolerant quantum computers capable of operating with millions of logical qubits. The current generation of Noisy, Intermediate-Scale Quantum (NISQ) devices, with their limited qubit counts and high error rates, are valuable for research but are incapable of solving these commercially relevant problems.

Market Growth and Total Addressable Market (TAM): The global quantum computing market was valued at $885.4 million in 2023 and is projected to reach $12.6 billion by 2032, demonstrating a robust compound annual growth rate (CAGR) of 34.8%. Over a longer timeframe, the total quantum technology market, which includes computing, communication, and sensing, could generate up to $97 billion in revenue worldwide by 2035.

Business Model & Traction

QuamCore's eventual business model will likely follow the industry standard, involving the direct sale of full-stack quantum computing systems to government labs and large enterprises, and/or providing access to their machines via a cloud-based quantum-computing-as-a-service (QCaaS) platform.

Given the early and young nature of the quantum industry, the business model is currently focused on securing B2B contracts. This approach allows QuamCore to partner directly with key players who are at the forefront of exploring quantum applications and are best positioned to invest in this nascent technology.

The company's traction to date is based on the strength of its intellectual property and its progress in the design phase. They have developed a fully detailed and simulated architecture for their million-qubit processor. With the successful closing of their Series A financing, they are now transitioning from the design and simulation phase to the physical fabrication of their first-generation prototype processors. A key part of this next phase is the establishment of a dedicated quantum laboratory in Israel to test and integrate their components.

The most significant traction is the validation of their novel architectural design by a syndicate of sophisticated deep-tech venture capitalists and the Israeli government, which contributed a non-dilutive grant via the Israel Innovation Authority, underscoring the national strategic importance of their approach.

Competitors

QuamCore competes within the most mature and heavily invested segment of the quantum computing industry: superconducting qubits. Its primary competitors are the large corporate labs and other venture-backed startups in this space. However, its unique architectural approach to solving the scaling problem serves as a key differentiator.

• Technology Giants: Google Quantum AI and IBM Quantum are the undisputed leaders in terms of current qubit counts, system performance, and cloud accessibility. However, their current scaling roadmaps are based on incremental improvements, such as linking multiple chips and eventually multiple cryostats together—an approach that faces the very cabling and complexity bottlenecks that QuamCore's architecture is designed to circumvent.

• Publicly Traded Startups: Rigetti Computing is a key public competitor, also focused on superconducting qubits and pursuing a multi-chip linking strategy for scaling.

• Private Startups: A number of innovative private companies are also working on superconducting platforms. These include Alice&Bob, which is developing self-correcting "cat" qubits to tackle errors at the hardware level, as well as Anyon Systems, Atlantic Quantum, and Bleximo, which are all pursuing novel approaches to qubit design and system integration.

The following table highlights the strategic differentiation between QuamCore and its main competitors.

Funding

QuamCore has raised a total of $35 million in financing to date, demonstrating significant capital efficiency in its R&D phase:

• Seed (March 2025): $9 million, a round led by Viola Ventures and Earth & Beyond Ventures.

• Series A (August 2025): $26 million, led by Sentinel Global. This round also included a $4 million non-dilutive grant from the Israel Innovation Authority.

The company's post-Series A valuation has not been publicly disclosed, but based on the funding amount and stage, it is likely in the low-to-mid hundred million dollar range. Within the context of the deep tech landscape, QuamCore presents a classic high-risk, high-reward investment profile and is arguably a significantly undervalued company.
