A QLSTM cell here = 4 gate-VQCs (forget/input/cell/output), each a 4–6 qubit ansatz: RX encode → RZ·RY·RZ variational layer → ring of CZ entanglers → measure ⟨Z⟩. The circuit runs gate-by-gate over a chosen qubit chain; every fault below is driven by the live calibration numbers, not simulated noise.
