    Securing quantum error correction against misleading advice from AI agents

    A. Barış Özgüler

    quant-ph · cs.AI · cs.CR · eess.SY

    Can an attacker turn influence over an artificial intelligence (AI) adviser into a harmful quantum error-correction update? We identify an ambiguity in passive syndrome records that obstructs recovery selection, then show how additional calibration measurements support certified recovery updates under uncertainty and drift. In an odd-distance square toric code with error-free preparation, syndrome measurements, and recovery operations,...

    Variational Quantum Transformer Architecture for Synthetic Language Generation

    Julian Hager, Michael Kölle, Gerhard Stenzel, Tobias Rohe, Jonas Stein, Claudia Linnhoff-Popien

    quant-ph · cs.CL · cs.LG

    We propose a compact NISQ-compatible quantum transformer architecture for synthetic QNLP sequence modelling. The model preserves the autoregressive next-token interface of a classical transformer, but replaces attention and feed-forward sublayers with variational quantum encoder blocks, connector circuits, decoder blocks and a direct two-qubit measurement readout. Token contexts are angle-encoded into small quantum registers, processed by...
