Quantum mechanics predicts correlations between measurements performed in distant regions of a spatially spread entangled state to be higher than allowed by intuitive concepts of Locality and Realism. These high correlations forbid the use of nonlinear operators of evolution (which would be desirable for several reasons), for they may allow faster-than-light signaling. As a way out of this situation, it has been hypothesized that the high quantum correlations develop only after a time longer than / has elapsed (where is the spread of the entangled state and is the velocity of light). In shorter times, correlations compatible with Locality and Realism would be observed instead. A simple hidden variables model following this hypothesis is described. It is based on a modified Wheeler-Feynman theory of radiation. This hypothesis has not been disproved by any of the experiments performed to date. A test achievable with accessible means is proposed and described. It involves a pulsed source of entangled states and stroboscopic record of particle detection during the pulses. Data recorded in similar but incomplete optical experiments are analyzed, and found consistent with the proposed model. However, it is not claimed, in any sense, that the hypothesis has been validated. On the contrary, it is stressed that a complete, specific test is absolutely needed.
量子力学预测，在空间扩展的纠缠态的遥远区域进行的测量之间的相关性，高于局域性和实在论的直观概念所允许的程度。这些高相关性禁止使用演化的非线性算符（出于多种原因，这是很理想的），因为它们可能允许超光速信号传递。作为摆脱这种情况的一种方法，有人假设高量子相关性仅在超过/的时间过去之后才会发展（其中是纠缠态的扩展，是光速）。在较短时间内，反而会观察到与局域性和实在论相容的相关性。描述了一个遵循这一假设的简单隐变量模型。它基于一种修正的惠勒 - 费曼辐射理论。该假设尚未被迄今为止进行的任何实验所证伪。提出并描述了一种用现有手段可实现的测试。它涉及一个纠缠态的脉冲源以及脉冲期间粒子探测的频闪记录。对在类似但不完整的光学实验中记录的数据进行了分析，发现与所提出的模型一致。然而，无论如何都不能声称该假设已得到验证。相反，强调绝对需要进行完整、具体的测试。
