Novel Macroscopic Violation of a Cauchy Schwarz Inequality Using Bunched and Unbunched Twin Beams
We have demonstrated unequivocal macroscopic violations of the Cauchy Schwarz inequalityl: [g 12 (2) (t)]2 ≤ g 11 (2) (0)g 22 (2) (0), for both hunched and antihunched incoherent light using a series connected pair of infrared emitting diodes2 to generate intensity-correlated twin beams of variable Fano factor, 30 > F i > 0.05. These results show clearly that the macroscopic violation is a fundamental quantum phenomenon, fully consistent with the “classical particle” model of incoherent light beam splitting suggested by Paul3.
