AI 中文摘要
Dicke态是多体纠缠态，其中固定数量的量子激发在大量量子比特间相干共享，最初在合作发射与超辐射背景下被提出，如今是量子传感、量子网络及集体量子现象的重要资源。然而，制备高保真度的指定Dicke态仍具挑战性，尤其随系统规模与激发数增大时。本文提供用于制备Dicke态的基于碰撞的量子协议的开放数据集及配套代码，该数据集涵盖5至14量子比特的系统、广泛的激发数范围，记录了最优无噪声制备保真度随电路深度的变化，还提供电路资源估计及在54量子比特IQM Emerald超导处理器上选定态的实验测量结果。配套代码可复现处理后的数据与验证检查，为研究态制备保真度、电路成本与硬件噪声间的权衡提供可复用的基准。
英文摘要
Dicke states are multipartite entangled states in which a fixed number of quantum excitations is coherently shared among many qubits. Originally introduced in the context of cooperative emission and superradiance, they are now important resources for quantum sensing, networking, and collective quantum phenomena. Preparing prescribed Dicke states with high fidelity, however, remains challenging, particularly as the system size and excitation number increase. Here we present an open dataset and accompanying code for preparing Dicke states using a collision-based quantum protocol. The dataset covers systems from five to fourteen qubits over a broad range of excitation numbers and records how the best-found noiseless preparation fidelity changes with circuit depth. It also provides circuit-resource estimates and experimental measurements for selected states on the 54-qubit IQM Emerald superconducting processor. The accompanying code reproduces the processed data and validation checks, providing a reusable benchmark for studying the trade-off between state-preparation fidelity, circuit cost, and hardware noise.
