Researchers suggest they’ve engineered a groundbreaking 3D cabling solution that enables a surge of 100 times in the quantity of quantum bits (qubits) a quantum computational circuit can handle.
Standard quantum processing units (QPUs) are designed utilizing two-dimensional, horizontal wiring, echoing the layout of central processing units (CPUs) found within conventional devices. However, this established wiring method restricts the amount of qubits that can be integrated onto any processor. Current offerings from giants like Google and IBM, for instance, incorporate roughly 105 and 120 qubits, respectively.

This adds up to a solo QPU possessing the ability to oversee 10,000 concurrent qubits — a 100-fold escalation relative to the current cutting edge in superconducting quantum computers — packed onto a more compact circuit. According to QuantWare, this marks the initial instance where such a qubit count has been realized on a single quantum processing unit.
“For a long time, people have contemplated quantum computing’s aptitude to revolutionize domains spanning from chemistry to materials science to energy solutions, yet the sector has remained anchored at QPUs featuring 100 qubits, compelling the field to hypothesize concerning engaging, yet distant, technologies,” expressed Matt Rijlaarsdam, the CEO of QuantWare, in the announcement. “QuantWare’s VIO ultimately negates this scaling impediment, opening the path for economically viable quantum computers. Thanks to VIO-40K, we are furnishing the broader ecosystem with entry to the mightiest, hyper-scaled quantum processing architecture ever conceived.”
Vertical integration meets quantum democratization
QuantWare delegates state they anticipate launching the initial VIO-40K components in 2028. In reinforcement of this objective, the company has plans to erect a factory for industrial-scale QPU construction in Delft, Netherlands, targeted to commence operations in 2026. It will be considered “among the largest quantum foundries globally” and the inaugural dedicated foundry for quantum open architecture (QOA) gadgets.
To situate this trajectory, IBM’s extant quantum computing evolutionary framework forecasts the debut of 2,000-qubit QPUs in 2033 or thereafter, without a determined timeframe for circuits equipped to handle 10,000 qubits.
The choke point, for the majority of corporations engaged with superconducting quantum computers, resides in the manner quantum processors are structured. Given that manufacturers can only fit a finite number of conductors onto an individual wafer, physicists must interconnect multiple processors. Although inter-qubit links on individual circuits exhibit elevated fidelity, inter-circuit bonds often demonstrate inferior fidelity, causing a bottleneck in data transference.
QuantWare’s VIO suite harnesses vertical cabling that supposedly allows as many as 10,000 qubits to be incorporated within a circuit more diminutive than today’s 100-qubit wafer designs. This is manifested through the utilization of “chiplet” technology that involves bonding independently produced modules to synthesize total circuits.
Rather than leaning on diminished-fidelity circuit-to-circuit connections employed in contemporary quantum processors, chiplets are constructed independently and then fused together to engender a system-on-a-chip setting adept at operating as an individual QPU.

A quantum brain in a box
QuantWare’s schedule is notably ambitious compared to its competitors; however, company personnel emphasize that the firm’s embracing of QOA constitutes a facilitating element.
Differing from Google and IBM, QuantWare does not dedicate itself to creating a full quantum computational solution. Its QPUs are assembled for interoperability with components sourced from third-party entities, such as Qblox controllers and Nvidia software.

—Scientists invent quantum computing virtual machines — they’ll slash turnaround times from days to hours
This signifies that the VIO-40K will essentially provide effortless integration with Nvidia NVQLINK — an architecture tailored to allow QPUs to interface with GPUs in a hybridized classical-quantum configuration — thus facilitating interaction with present-day supercomputers. This would also enable interaction with Nvidia CUDA — a concurrent computing platform and programming framework — empowering developers to naturally integrate complete quantum processes within the hybrid systems.
Ultimately, this positions QuantWare to conceivably function as an Intel-akin hardware purveyor for quantum computing systems, collaborating with fellow quantum computing establishments in the endeavor.
