我们研究的实施与线性光学二元投影测量。这个问题可以看作是对两个正交纯量子态的单次判别。我们表明，任何两个正交的状态可以完全区分使用线性光学，光子计数，相干辅助状态，和前馈。这种说法在大量这些物理资源的渐近极限中成立。
We investigate the implementation of binary projective measurements with linear optics. This problem can be viewed as a single-shot discrimination of two orthogonal pure quantum states. We show that any two orthogonal states can be perfectly discriminated using only linear optics, photon counting, coherent ancillary states, and feedforward. The statement holds in the asymptotic limit of a large number of these physical resources.
