We study properties of quantum strategies, which are complete specifications of a given party's actions in any multiple-round interaction involving the exchange of quantum information with one or more other parties. In particular, we focus on a representation of quantum strategies that generalizes the Choi-Jamio{\l}kowski representation of quantum operations. This new representation associates with each strategy a positive semidefinite operator acting only on the tensor product of its input and output spaces. Various facts about such representations are established, and two applications are discussed: the first is a new and conceptually simple proof of Kitaev's lower bound for strong coin-flipping, and the second is a proof of the exact characterization QRG = EXP of the class of problems having quantum refereed games.

  1. Coherent Swap Regret and Channel-Proof Learning

    quant-ph 2026-06 unverdicted novelty 7.0

    Introduces coherent swap regret against local CPTP maps and proves a three-level landscape where non-unital measurement-preparation channels force Theta(sqrt(d T log d)) minimax regret while unital channels have zero regret.

  2. Temporal Kirkwood-Dirac Quasiprobability Distribution and Unification of Temporal State Formalisms through Temporal Bloch Tomography

    quant-ph 2026-01 conditional novelty 6.0

    A generalized Kirkwood–Dirac distribution for multi-time processes unifies pseudo-density operators, doubled density operators, and related temporal state formalisms via temporal Bloch tomography.

  3. Temporal State Tomography via Quantum Snapshotting the Temporal Quasiprobabilities

    quant-ph 2026-05 unverdicted novelty 5.0

    Temporal state tomography reconstructs multi-time quantum processes from temporal quasiprobability distributions via a Bloch-type representation and derives the associated sample complexity.
