Tianyan-287

тип кубита: tunable transmon

механизм вентиля: tunable coupler; explicitly a Zuchongzhi 3.0-like architecture; iSWAP-like (fSim) two-qubit gate at a fixed 40 ns, single-qubit gates 26 ns with DRAG (arXiv:2512.10504); the cloud's native gate set in the owner SDK: RZ, X2P, X2M, Y2P, Y2M, XY2P, XY2M, CZ (cqlib-tianyan device_config.rs, Sep 2026); the AshN scheme (simultaneous XY drives on both qubits with the tunable coupler) gives a native set of CZ 48 ns, iSWAP 44 ns, √iSWAP 28 ns, SWAP 60 ns and a B-like gate 44 ns on the 105-qubit, 182-coupler device of arXiv:2608.24084 (CTQG with Tsinghua, Aug 2026; the paper names the architecture, not the machine)

связность: square grid lattice, 105 qubits and 182 couplers (the owner's wording, arXiv:2512.10504)

управление: room-temperature RF; per-qubit XY and Z lines combined at room temperature through a bias tee before the refrigerator, coupler lines routed separately (arXiv:2608.24084)

размещение управления: room-temp

считывание: dispersive; X12-gate-driven 0–2 readout, correlated readout errors below 2 % with a synchronous SPAM protocol (arXiv:2512.10504); a TWPA at the mixing-chamber stage and a HEMT at 4 K (arXiv:2608.24084)

свидетельство вентиля: число, названное производителем, без протокола

флаги: оценочная база, название — не число кубитов
