AI 中文摘要
强电磁背景使量子电动力学成为一个涉及 dressed 费米子和动态光子的实时非微扰问题。我们提出一种用于在 Furry 图景中模拟 3+1 维强场量子电动力学的囚禁离子协议。该构造将光子模式编码在集体声子中，将 Volkov dressed 费米子模式编码在离子自旋中，结合了原生自旋-声子耦合与压缩非局部 Jordan-Wigner 串的 Clifford 电路。对于非线性 Breit-Wheeler 对产生，该协议具有多项式资源缩放，并针对具有受控 Trotter 误差的精确单模动力学进行了基准测试。通过实验激发的声子加热和退相，零噪声外推大大减少了光子存活和对产生信号的偏差。这些结果为超越微扰或静态场描述的强场粒子产生动力学提供了一条硬件高效的途径。
英文摘要
Strong electromagnetic backgrounds make quantum electrodynamics a real-time nonperturbative problem involving dressed fermions and dynamical photons. We propose a trapped-ion protocol for simulating intense-field QED in $3+1$ dimensions in the Furry picture. The construction encodes photon modes in collective phonons and Volkov-dressed fermion modes in ion spins, combining native spin-phonon couplings with Clifford circuits that compress nonlocal Jordan--Wigner strings. For nonlinear Breit--Wheeler pair production, the protocol has polynomial resource scaling and is benchmarked against exact single-mode dynamics with controlled Trotter errors. With experimentally motivated phonon heating and dephasing, zero-noise extrapolation substantially reduces deviations in photon-survival and pair-production signals. These results provide a hardware-efficient route to intense-field particle-production dynamics beyond perturbative or static-field descriptions.
