Is measurement-based feedback still better for quantum control systems?
In this paper, we put forward a fundamental question concerning feedback control of quantum systems: Is measurement-based feedback control still better than openloop control? In c...

Quantum Mereotopology
: Mereotopology faces problems when its methods are extended to deal with time and change. We offer a new solution to these problems, based on a theory of partitions of reality wh...

The Equivalence of Sampling and Searching
In a sampling problem, we are given an input x {0, 1} n , and asked to sample approximately from a probability distribution Dx over poly (n)-bit strings. In a search problem, we ...

Robust Polynomials and Quantum Algorithms
We define and study the complexity of robust polynomials for Boolean functions and the related fault-tolerant quantum decision trees, where input bits are perturbed by noise. We ...
