The EPO published Microsoft Technology Licensing LLC's patent application EP4010853A1 on March 25, 2026, covering a pipelined hardware decoder architecture for quantum computing devices. The invention addresses quantum error correction decoding with a hardware implementation designed for improved throughput. The application names eight inventors including Poulami Das, Nicolas Delfosse, Krysta Svore, and Helmut Katzgraber. Designated states include all EPO member states covering major European markets.

This is a patent publication rather than a regulatory action imposing obligations. Technology companies developing quantum computing hardware or error correction systems should be aware of Microsoft's claimed intellectual property in pipelined decoder architectures. Companies should review the published claims during the patent examination process if potential overlap exists with their own quantum computing technologies. No compliance deadlines or penalties are associated with this publication.
