Quantum Transistors, a pioneer in advanced quantum processor development has achieved a world-record fidelity rate of 99.9988% – a crucial step toward broader access to quantum computing.<\/p>\n\n\n\n

By harnessing diamond-based quantum processors, Quantum Transistors is working to overcome the limitations faced by different qubit technologies that rely on expensive, low-Kelvin cryogenic cooling to combat environmental noise.<\/p>\n\n\n\n

While trying to achieve scale, environmental noise is a major challenge, one which results in high error rates and lowers fidelity, leading to significant costs associated with error correction. By using diamonds as its base quantum material, Quantum Transistors has simultaneously achieved better performance required for scale, while reducing reliance on expensive cryogenic systems.<\/p>\n\n\n\n

With more than US$55bn ploughed into quantum computing to date, and an international quantum \u2018arms race\u2019 taking place, Quantum Transistors’ breakthrough represents a key milestone in the journey to making quantum computing more cost-effective and accessible.<\/p>\n\n\n\n

\u201cThis milestone is an important indication of what\u2019s possible,\u201d said Shmuel Bachinsky, CEO and Co-Founder, Quantum Transistors.<\/p>\n\n\n\n

\u201cThis 9-fold improvement in fidelity makes it easier to build more scalable systems that are needed to handle real world challenges. At the same time, having a platform that works from room temperature to cryogenic temperatures allows us to avoid having to build sub-1k dilution refrigeration and tailor our solution to specific applications. This achievement places diamond-based qubits on a credible path toward scalable, fault-tolerant quantum computers that are more accessible and practical to own.\u201d<\/p>\n\n\n\n

Quantum Transistors has developed a novel technique dubbed \u2018PUDDINGs\u2019 (Power-Unaffected, Double-Detuning-Insensitive Gates), engineered to protect quantum information from multiple sources of interference that typically corrupt qubit operations. PUDDINGs reshape the control pulses used to operate qubits, adding layered protection that cancels multiple types of noise at once.<\/p>\n\n\n\n

Borrowing principles from MRI, the technique drives errors down quadratically instead of linearly, enabling far sharper gains with each refinement. It also represents the first experimental demonstration of error-protected two-qubit gates in a solid-state system.<\/p>\n\n\n\n

The findings point to the potential of diamond-based architectures to support the next generation of quantum computing.<\/p>\n\n\n\n
