标题： Are Retrocausal Accounts of Entanglement Unnaturally Fine-Tuned?

摘要： 使用一个显式的回溯因果模型来分析Wood-Spekkens的普遍论点[1]，即任何对贝尔不等式违背的因果解释都必须不自然地微调以避免信号传递。 该模型的无信号特性在仅有的自由参数变化下依然稳健，即使概率偏离了标准量子理论。 这种稳健性的最终原因是追溯到原始模型所假设的对称性。 更广泛的结论是，基于对称性的限制似乎是一种自然且可接受的微调形式，而不是不自然的模型调整。 如果Wood-Spekkens的论点表明存在隐藏的对称性，这甚至可以被解释为支持时间对称的回溯因果模型。 显示英文摘要

摘要： An explicit retrocausal model is used to analyze the general Wood-Spekkens argument [1] that any causal explanation of Bell-inequality violations must be unnaturally fine-tuned to avoid signaling. The no-signaling aspects of the model turn out to be robust under variation of the only free parameter, even as the probabilities deviate from standard quantum theory. The ultimate reason for this robustness is then traced to a symmetry assumed by the original model. A broader conclusion is that symmetry-based restrictions seem a natural and acceptable form of fine-tuning, not an unnatural model-rigging. And if the Wood-Spekkens argument is indicating the presence of hidden symmetries, this might even be interpreted as supporting time-symmetric retrocausal models.
