纠缠光子间瞬时影响的直接观测

Direct Observation of Instantaneous Influence between Entangled Photons

摘要:

我们研究了量子非局域性的直接观测,除了量子力学的理论模型(包括贝尔定理),与一个二分偏振纠缠态,其中一个光子立即减少到一个圆偏振(CP)状态后,其伙伴被检测到在另一个CP状态。本质上是对光子CP态的机械检测,光子携带角动量并对半波片施加扭矩,然后改变半波片的机械运动。如果实现,量子非定域性的模型无关观测在实验中违反了洛伦兹不变性,并可能表明新的基础物理超越了标准模型。

英文摘要:

We investigate direct observation of quantum nonlocality without reference to theoretical models (including Bell theorem) except quantum mechanics, with a bipartite polarization-entangled state in which one photon immediately reduces into a circular-polarization (CP) state after its partner is detected in another CP state. Of essence is the mechanical detection of the CP state of a photon that carries angular momentum and exerts a torque on a half-wave plate whose mechanical motion is then varied. If implemented, the model-independent observation of quantum nonlocality violates Lorentz invariance in experiment and may indicate new fundamental physics beyond the Standard Model.
