冯·诺伊曼提出量子测量中“波函数坍缩”可能终止于“观察链”的观察者意识后,维格纳提出“维格纳朋友”思想实验引出著名的悖论,量子贝叶斯主义(QBism)认为该悖论违背了“QBist的哥白尼原理”,维格纳不能把朋友看作跟自己不一样的主体,这跟梅洛-庞蒂身体现象学中“一只手触碰另一只手”的情形是一样的。我们进一步从主动推理的计算现象学角度更具体地消解了维格纳朋友悖论。
After von Neumann proposed that the “wave function collapse” in quantum measurement might terminate at the observer's consciousness in the “observation chain”, Wigner introduced the “Wigner's friend” thought experiment, leading to a famous paradox. Quantum Bayesianism (QBism) argues that this paradox violates the “QBist Copernican principle”, asserting that Wigner cannot treat his friend as a subject fundamentally different from himself. This perspective aligns with the scenario in Merleau-Ponty's body phenomenology of “one hand touching the other”. Furthermore, from the perspective of computational phenomenology based on active inference, we provide a more concrete resolution to the “Wigner's friend” paradox.
