Projective measurement of the two-photon polarization state: Linear optics approach
Andrzej Grudka, Antoni Wójcik · Physical Review A · 2002
We present a method of implementation of general projective measurement of the two-photon polarization state with the use of linear optics elements only. The scheme presented succeeds with a probability of at least 1/16. For some specific measurements (e.g., parity measurement) this probability reaches 1/4.
