Q9. In the setup below, if the initial states for ABC and DE are 1/V2 | H)A| H)B| H)c - 1/V2 IV)AlV)BIV)c and 1/V2 [ H)DIV)E + 1/V2 [V)D/ H), respectively, and the two-photon measurement outcome is VH, what is the final state of ABE? A. 14 [ H)A | H)B | H) E - /4 IV)A IV) BIV )E B. 14 | H)A | H)B/ H) E + /4 |V)AIV) BIV )E V H C. 14 | H)A | H ) BIV ) E - 14 | V )AIV ) BI H) E BS D. /4 | H) A | H) BIV ) E + 14 | V ) A / V ) B | H ) E A B D E 1/V2 [H)A [H)= [ H) c 1/V2 [ H) DIVE -1/V2 [V)A IV): IV )c + 1/v2 [ V) D | H) E
