量子有限查询复杂度

Quantum Bounded Query Complexity

Harry Buhrman, Wim van Dam

摘要:

我们结合了经典的概念和技术,有界查询类与那些在量子计算。我们给出了强有力的证据,量子查询的预言机类NP确实降低了查询的复杂性决策问题。在传统的复杂性假设下,我们得到了函数类的量子和经典查询复杂性之间的指数加速比。对于决策问题和函数类,我们得到以下结果:||^NP[2k]包含在EQP中。||^NP[k] o P_||^NP[2^(k+1)-2]包含在EQP中^NP[k] o FP_||^NP[2^(k+1)-2]被包括在FEQP^NP[2k]中。||^NP包含在FEQP^NP中[O(log n)]对于对于PSPACE或EXP为多-一完全的集合A,我们证明FP^A包含在FEQP^A中[1]。对于PP为多-一完全的集合A具有FP_||^A包含在FEQP^A中[1]。一般来说,我们证明了对于任何集合A,存在一个集合X使得FP^A包含在FEQP^X中[1],建立了在量子设置中没有集合是超简洁的。

英文摘要:

We combine the classical notions and techniques for bounded query classes with those developed in quantum computing. We give strong evidence that quantum queries to an oracle in the class NP does indeed reduce the query complexity of decision problems. Under traditional complexity assumptions, we obtain an exponential speedup between the quantum and the classical query complexity of function classes. For decision problems and function classes we obtain the following results: o P_||^NP[2k] is included in EQP_||^NP[k] o P_||^NP[2^(k+1)-2] is included in EQP^NP[k] o FP_||^NP[2^(k+1)-2] is included in FEQP^NP[2k] o FP_||^NP is included in FEQP^NP[O(log n)] For sets A that are many-one complete for PSPACE or EXP we show that FP^A is included in FEQP^A[1]. Sets A that are many-one complete for PP have the property that FP_||^A is included in FEQP^A[1]. In general we prove that for any set A there is a set X such that FP^A is included in FEQP^X[1], establishing that no set is superterse in the quantum setting.
