Abstract

An oracle is constructed relative to which quantum polynomial time (EQP) is not polynomial-time Turing reducible to NP. That is, there is an A such that EQPA ⊈ PNPA. This generalizes and simplifies previous separations of EQP from NP and ZPP, due to Berthiaume and Brassard. A key element of the proof is the use of a special property of Grover's algorithm for database search, in order to show that the test language is in EQPA. © 2001 Elsevier Science B.V.
