Silicon Quantum Computing (SQC) has announced unprecedented accuracy in operating Grover’s algorithm, marking a milestone in the global race to harness this transformative technology. With a demonstrated accuracy of up to 98.9%, SQC’s quantum processor outperforms any other system currently available, positioning the company as a leading contender in the quest for reliable, large-scale quantum computing.
The achievement underscores SQC’s strategic advantage in prioritizing qubit quality and precision manufacturing. As Michelle Simmons, SQC’s Founder and CEO, emphasizes, these areas hold the key to scalability, commercial applications, and unlocking quantum technology’s full potential.
High-quality qubits, naturally formed from phosphorus atoms and precision-engineered in pure silicon, are central to SQC’s strategy. These qubits exhibit longer coherence times, higher stabilities, and lower error rates, paving the way for an efficient and economical quantum computer.
Furthermore, SQC’s ultra-high precision proprietary manufacturing enables the construction of silicon chips at the atomic scale. This in-house manufacturing process allows for rapid iterations of chip designs, significantly faster than competitors who rely on external inputs and suppliers.
The study’s authors, including Simmons herself, have published their findings in Nature Nanotechnology, offering a promising path toward commercial-scale quantum computing. As SQC continues to post market-leading progress, the race to unlock quantum technology’s full potential heats up.
Michelle Simmons, Founder and CEO of SQC, hailed the achievement as a validation of their quality-first approach. “In the race to deliver commercially viable quantum computers,” she stated, “what truly matters is not the number of qubits, but their quality.”
Grover’s algorithm, a foundational algorithm for fast database searching, was instrumental in igniting the race towards quantum computing. SQC’s quantum processor demonstrated up to 98.9% accuracy of Grover’s algorithm’s theoretical maximum, significantly surpassing any other quantum system.
The results were published in Nature Nanotechnology on February 20, 2025, positioning SQC as a frontrunner in the quest for a commercial-scale quantum computer.
Simon Segars, SQC’s Chair and former ARM CEO, emphasized the multiple strategic advantages that SQC holds due to its high-quality qubits and atomic-scale manufacturing. These factors position SQC as a leader in developing quantum computers capable of delivering reliable, real-world, commercial solutions.
High error rates are a significant barrier in creating quantum computers. Unlike other quantum technology platforms that utilize artificially manufactured qubits, SQC’s qubits are naturally formed from phosphorus atoms, precision-engineered within pure silicon.
These qubits exhibit longer coherence times, higher stabilities, and lower error rates, paving the way for a high-performing, efficient, and economical quantum computer.
SQC’s ultra-high precision proprietary manufacturing enables the construction of silicon chips with features at the atomic scale. This fully integrated in-house manufacturing process allows SQC to rapidly iterate chip designs within 1-2 weeks, significantly faster than other quantum computing companies that rely on third-party inputs and suppliers.
Simmons expressed optimism about the future, stating, “Our record performance on Grover’s algorithm validates our path and the strength of our qubit manufacturing and precision engineering.” She looks forward to more market-leading progress in the field of quantum computing.
