(PRX Quantum, 2026) proved that the Schrodinger and Heisenberg pictures disagree about memory. The same phase-covariant qubit channel is CP-divisible (memoryless) in the Schrodinger picture and P-indivisible (memory-bearing) in the Heisenberg picture. Three views: dual Bloch sphere evolution with trace vs operator-norm distances, left and right generator rates showing where negativity appears, and operational guessing games for states vs effects.","shortDescription":"Whether a system has memory depends on who's asking"}}
