We study a general family of quantum protocols for position verification and present a new class of attacks based on the Clifford hierarchy. These attacks outperform current strategies based on port-based teleportation for a large class of practical protocols. We then introduce the Interleaved Product protocol, a new scheme for position verification involving only the preparation and measurement of single-qubit states for which the best available attacks have a complexity exponential in the number of classical bits transmitted.

  1. Uncountably many inequivalent maximally entangled measurements for two qutrits

    quant-ph 2026-07 conditional novelty 7.0

    There are uncountably many locally inequivalent maximally entangled measurement bases for two qutrits, constructed from qutrit SICs, including the first wild error bases in dimension 3.
