A framework of partial error correction for intermediate-scale quantum computers

A research paper presenting a framework for partial quantum error correction on intermediate-scale quantum computers. The work addresses the transitional period between noisy small-scale and fully fault-tolerant quantum systems, developing logical operations on hybrid systems combining noisy and error-corrected qubits. Under Pauli noise assumptions, analytic and numerical evidence shows that brick-layered circuits with a fraction of error-corrected qubits exhibit slower decoherence compared to fully noisy circuits. Crucially, this advantage only appears once the number of error-corrected qubits surpasses a threshold determined by the coupling count between error-corrected and noisy registers.

South Korea Commits 200 Trillion Won to R&D, Quantum Listed as Strategic Tech

South Korea has finalized its Sixth Basic Plan for Science and Technology, committing over 200 trillion won to government R&D from 2026 to 2030. Quantum technologies are designated as one of 10 national strategic technology fields, with 60 trillion won earmarked for 55 technologies across those fields. The plan also targets AI infrastructure expansion, 6G development, semiconductor clusters, and regional R&D special zones. A mission-oriented research model will replace the previous project-based funding system, potentially benefiting long-horizon fields like quantum computing, secure communications, and quantum sensing. No quantum-specific budget figure was disclosed, but the inclusion signals a long-term national security and economic commitment to the field.

BTQ Finalizes QPerfect Acquisition Following French Approval

BTQ Technologies has finalized its acquisition of QPerfect SAS, a French quantum software company based in Strasbourg, after receiving French Foreign Direct Investment regulatory approval. The deal, valued at approximately €18.6M at closing plus up to €5.7M in earnout payments, adds QPerfect's three core technologies to BTQ's portfolio: MIMIQ (a quantum emulator capable of stable 100+ qubit simulations), Digital Twin (quantum system modeling), and QLU (a multi-layered quantum control framework). France imposed conditions requiring QPerfect to maintain its registered office in France, continue R&D activities, and protect its intellectual property. The acquisition establishes Strasbourg as BTQ's European R&D hub, supporting development of quantum-ready infrastructure, post-quantum cryptography migration validation, and secure communications for defense, telecom, and critical infrastructure sectors.

IQM Completes Business Combination with RAAQ and Lists on Nasdaq

IQM Quantum Computers has completed its business combination with Real Asset Acquisition Corp. (RAAQ), a Nasdaq-listed SPAC, and will begin trading on Nasdaq under the ticker IQMX on July 2, 2026. The transaction, including a concurrent PIPE investment of EUR 127.7 million, provides IQM with approximately EUR 198.7 million (USD 233.5 million) in net proceeds. Founded in 2018, IQM is a full-stack superconducting quantum systems provider serving enterprises, research institutions, and national laboratories across Europe, North America, and Asia. The funds will support commercialization and global expansion of its quantum computing business.

Wave Photonics Adds Synopsys OptoCompiler Support for Its PDK Platform

Wave Photonics has made all PDKs on its PDK Management Platform compatible with Synopsys OptoCompiler, the industry's first unified electronic and photonic design platform. Designers can now access photonic design kits covering multiple materials and wavelengths — from blue to telecoms bands — for applications including datacomms, quantum technologies, and sensing. PDKs include pre-calculated S-parameters for simulation in Synopsys OptSim before tape-out. For foundries like CORNERSTONE, the integration simplifies PDK distribution, version tracking, documentation generation, NDA tracking, and IP protection, reducing overhead of maintaining multiple PDK integrations.

Optimal control for Rydberg multi-qubit operations

Researchers use quantum optimal control techniques to design single continuous laser pulses that implement multi-qubit controlled-phase and controlled-SWAP (Fredkin) gates on Rydberg atom quantum processors. The approach reduces operation time and decoherence while providing continuous protection from environmental noise. The Fredkin gate achieves 99.88% fidelity even when accounting for real-world imperfections such as spontaneous emission, laser fluctuations, and Doppler dephasing.
