QIP = PSPACE
QIP = PSPACE
摘要:
我们证明了复杂性类QIP,其中包括所有的问题,量子交互式证明系统,包含在PSPACE。这种包容性证明了通过应用并行化形式的矩阵乘性权重更新方法的一类半定程序,捕获量子交互式证明的计算能力。由于PSPACE在QIP中的包容性直接来自众所周知的等式IP = PSPACE,等式QIP = PSPACE随之而来。
英文摘要:
We prove that the complexity class QIP, which consists of all problems having quantum interactive proof systems, is contained in PSPACE. This containment is proved by applying a parallelized form of the matrix multiplicative weights update method to a class of semidefinite programs that captures the computational power of quantum interactive proofs. As the containment of PSPACE in QIP follows immediately from the well-known equality IP = PSPACE, the equality QIP = PSPACE follows.
