Australian researchers have achieved a significant breakthrough in the development of metal-oxide-semiconductor-based (MOS-based) quantum computer systems, marking a crucial step forward in the quest for scalable and reliable quantum computing. Researchers have reported a significant milestone in the development of robust quantum computing technology: their two-qubit gates achieve error-free operation at a remarkable 99 percent rate. This critical quantity serves as the foundation for undertaking complex projects, widely regarded as indispensable in building ambitious large-scale initiatives. With MOS-based quantum computing architectures being compatible with existing CMOS technology, fabricating multiple qubits on a single chip becomes significantly easier and more feasible compared to alternative approaches.
“According to the chief commercial officer of our company, achieving a consistency rate above 99% is crucial because many assume this marks the error correction threshold. If your consistency falls below this benchmark, it doesn’t matter what approach you take for error correction.” “You won’t catch up on mistakes any faster than new ones arise.”
Several competing platforms vie for dominance in the quest to develop a practical quantum computer. Scientists at IBM’s Thomas J. Watson Research Center and other researchers are struggling to scale up the number of functional superconducting qubits.

Researchers at UNSW have joined forces with a Sydney-based startup, along with international collaborators from Japan, Germany, Canada, and the US, to pioneer an innovative approach: confining individual electrons within MOS devices. According to Dr., an analysis fellow at UNSW, their objective is to create qubits that can approach the functionality of traditional transistors in terms of efficiency and scalability.
Qubits That Act Like Transistors
The qubits exhibit striking similarities to a daily gate, carefully designed to confine a single electron within the channel. The primary advantage of this approach lies in its potential to be fabricated using established scientific methodologies, thereby enabling the possibility of scaling up to hundreds of thousands of qubits on a solitary microchip. Another advantage of MOS qubits is their ability to be integrated directly onto a chip alongside traditional transistors, simplifying input/output and management processes, according to Dr. Amir Qasemi, CEO of Diraq.
Although this strategy has its advantages, a significant drawback is the inherent device-to-device variability in MOS qubits, which can introduce substantial noise affecting their performance.
Because of the inherent nature of their operation, the sensitivity in MOS qubits is poised to surpass that of transistors, with the latter still relying on the collective movement of 20, 30, or even 40 electrons to carry a current. According to John, a senior machine engineer for quantum hardware, “You’re literally getting down to a single electron in a qubit machine.”
The test results showed that the crew’s quantum processors achieved an impressive 99% accuracy in executing two-qubit gates across multiple devices, while also shedding light on the underlying causes of device-to-device variability. The team carefully scrutinised a trio of cutting-edge devices, each boasting an impressive three quantum bits (qubits). To further quantify the error cost, the researchers also conducted a comprehensive study to uncover the fundamental physiological processes that give rise to noise.
Researchers uncovered a significant source of noise: isotropic impurities in the silicon layer, which, once controlled, significantly simplified the circuit complexity required to operate the machine. A subtle irregularity in the oxide layer’s integrity could have led to minute fluctuations in the electrical field, subsequently contributing to noise. It’s claimed that an upgrade is feasible by transferring from a controlled laboratory setting to a foundry environment.
What a remarkable outcome! According to Pillarisetty, this approach is setting the stage for a thought-provoking neighbourhood exploration that moves beyond individual machines and demonstrates scalability in its long-term trajectory.
As the challenge lies in scaling up these devices to additional qubits? The scalability challenge lies in accommodating a diverse range of input and output channels. The researchers at a cutting-edge institution, dedicated to advancing the field of quantum computing, have recently developed a pioneering chip called, which aims to tackle this pressing issue. The Pando tree’s unique substrate is expected to mirror that of the quantum processor, facilitating expedited data exchange between qubits. The Intel team aims to leverage this technology to exponentially scale their quantum computing capabilities to thousands of qubits. “Notably, our approach involves contemplating how to make our qubit processor resemble a modern CPU in its design,” states Pillarisetty.
Accordingly, Diraq’s CEO, Dzurak, reveals that his team intends to amplify their proficiency to thousands of qubits in the near future through a strategic partnership. “With WorldFoundries, we designed a chip capable of hosting thousands of MOS-based qubits.” These connections will likely be intertwined through a sophisticated network of classical transistor circuits carefully crafted by our team. In a move that defies conventional understanding in the realm of quantum computing, Dzurak notes.
