Research demonstrates error verification without qubit movement, enhancing quantum computing scalability
BTQ Technologies, a global quantum security company, announced on the 16th that the results of its joint research with Australia's Macquarie University on 'Quantum Error Correction Utilizing Neutral Atom Computing' were published in the international academic journal *Physical Review Research* under the American Physical Society (APS).
This paper was led by BTQ Technologies' Chief Quantum Officer (CQO) Gavin Brennen and demonstrated an 'error verification method without qubit movement' that enables large-scale expansion of quantum computing.
Through this research, Gavin Brennen, CQO, proved that on high-performance quantum low-density parity-check (qLDPC) codes, multiple qubits can be verified simultaneously without physically moving them. By performing error measurements within fixed steps using a neutral atom platform for quantum computers, the study significantly reduces control complexity and enhances system scalability.
Additionally, the joint research team from BTQ Technologies and Macquarie University demonstrated in this paper that quantum computers can be implemented in a 'fault-tolerant form' capable of stably correcting quantum errors even in real-world environments. This was achieved by simplifying qubit control processes using quantum entanglement, showing that efficient error correction is possible with much simpler hardware configurations compared to existing methods.
The significance of this research lies in proposing a practical methodology implementable with current research-level equipment, beyond merely presenting a theoretical model. It aligns precisely with BTQ Technologies' mid- to long-term 'Neutral Atom Roadmap' for quantum computing, expected to accelerate applications in quantum communication, cryptography, and security fields.
This achievement is anticipated to serve as a foundation for developing fault-tolerant quantum computing prototypes. The proposed method could expand into quantum systems capable of long-duration operations, enabling more complex algorithms and commercializable quantum-secured communication and cryptography. BTQ Technologies plans to extend this result into global core industries such as quantum-secured communication, finance, defense, and telecommunications through quantum networks.
Furthermore, BTQ Technologies will continue joint research with Macquarie University and apply the error correction techniques presented in this paper to simulations and neutral atom computing hardware design. It also aims to concretize pathways for scaling large quantum systems and accelerate convergence with quantum security networks and post-quantum cryptography (PQC) technologies.
BTQ Technologies' CSO Choi Young-seok stated, "This research is significant as it presents a new methodology to control existing quantum systems more simply and stably through neutral atom computing. BTQ Technologies will expand this technology to a commercial level through collaboration between academia and industry, accelerating the realization of practical quantum security infrastructure."
