AI 中文摘要
频分复用超导量子比特控制不仅需要载波分配，共享源的射频预算还会通过有限带宽、峰值因数、削波、量化、抖动、杂散、压缩、串扰和泄漏等因素扰动多量子比特旋转。本文提出一种射频预算帧编译与验证工作流，结合量子比特控制身份（QID）记录、基于MATLAB/Simulink的电路感知RFSoC源链模型、QuTiP qutrit动力学以及Qiskit衍生的算法工作负载。QID记录编码量子比特特有的计算与泄漏跃迁频率、脉冲参数及驱动尺度校准，而射频链轮廓和有效串扰耦合矩阵作为编译器的独立输入。候选多音射频帧在射频预算约束下调度，经RFSoC模型传播后解码为计算与泄漏跃迁帧，在QuTiP中评估旋转误差、感知泄漏的保真度、计算子空间存活度及瞬态泄漏。研究从单qutrit脉冲闭合推进至成对共存、多音射频帧容量，以及从Qiskit电路提取的Bernstein-Vazirani（BV）和QAOA微波层。仿真显示，更长脉冲提升每帧聚合度但未必最小化时间归一化层成本；聚类频率图、更大旋转及多音泄漏堆叠收紧闭合。在标称射频预算下，Qiskit衍生的12量子比特BV-Y90层在240 ns内闭合于3个验证过的四音帧，而QAOA混频器分区随旋转角和脉冲时长变化。所有报告结果均为基于模型、无退相干的仿真诊断，而非实测硬件保真度或布线缩减声明。
英文摘要
Frequency-multiplexed superconducting-qubit control requires more than carrier assignment: the RF budget of a shared source can perturb multi-qubit rotations through finite bandwidth, crest factor, clipping, quantization, jitter, spurs, compression, crosstalk, and leakage. We present an RF-budgeted frame-compilation and validation workflow that combines qubit-control identity (QID) records, a MATLAB/Simulink-based circuit-informed RFSoC source-chain model, QuTiP qutrit dynamics, and Qiskit-derived algorithm workloads. QID records encode qubit-specific computational and leakage transition frequencies, pulse parameters, and drive-scale calibration, while the RF-chain profile and effective crosstalk-coupling matrix are provided as separate compiler inputs. Candidate multitone RF frames are scheduled under RF-budget constraints, propagated through the RFSoC model, decoded into computational and leakage transition frames, and evaluated in QuTiP for rotation error, leakage-aware fidelity, computational-subspace survival, and transient leakage. The studies progress from single-qutrit pulse closure to pairwise coexistence, multitone RF-frame capacity, and Bernstein-Vazirani (BV) and QAOA microwave layers extracted from Qiskit circuits. The simulations show that longer pulses improve per-frame aggregation but do not necessarily minimize time-normalized layer cost; clustered frequency maps, larger rotations, and multitone leakage stacking tighten closure. Under the nominal RF budget, a Qiskit-derived 12-qubit BV -Y90 layer closes in three validated four-tone frames at 240 ns, while QAOA mixer partitions vary with rotation angle and pulse duration. All reported results are model-based, decoherence-free simulation diagnostics rather than measured hardware fidelities or wiring-reduction claims.
