• The Breakthrough: Microsoft researchers have unveiled a new "4D geometric code" that they claim can reduce errors in quantum computers by a factor of 1,000. This novel approach is designed to significantly improve the stability and reliability of quantum calculations.

• How it Works: The new method utilizes a four-dimensional geometric structure to detect and correct errors in qubits without disrupting their quantum state. This "twisted" code creates a more comprehensive map of the quantum system, allowing for more efficient error detection.

• Next Steps: The findings, published on the preprint server arXiv, are yet to be peer-reviewed. However, if validated, this could represent a monumental step towards achieving fault-tolerant quantum computers, a major bottleneck in the field.

• Congressional focus: Rep. Nancy Mace’s Cybersecurity Subcommittee will convene on 24 June to examine quantum threats to current encryption.

• Star witness list: IBM Quantum, GAO, and Qrypt executives will brief lawmakers on readiness and the push for post-quantum cryptography.

• Policy momentum: The hearing follows the 2022 Quantum Computing Cybersecurity Preparedness Act, signalling bipartisan urgency to future-proof federal data.

• A Magical Advancement: Researchers at the University of Osaka have developed a much more efficient method for creating "magic states," which are essential ingredients for fault-tolerant quantum computing. These special quantum states are notoriously difficult and resource-intensive to produce.

• Reduced Overhead: The new technique promises to make the creation of magic states easier, faster, and less "noisy." This directly addresses the significant overhead that has been a major hurdle in building scalable, error-corrected quantum computers.

• Path to Practicality: By streamlining the production of these crucial states, the researchers have cleared a significant roadblock on the path to building quantum computers that can perform long, complex calculations without being derailed by errors.
