Generalized Performance of Concatenated Quantum Codes -- A Dynamical Systems Approach
Jesse Fern, Julia Kempe, Slobodan Simic +1
We apply a dynamical systems approach to concatenation of quantum error correcting codes, extending and generalizing the results of Rahn et al. [1] to both diagonal and nondiagonal…
The hidden subgroup problem and permutation group theory
Julia Kempe, Aner Shalev
We employ concepts and tools from the theory of finite permutation groups in order to analyse the Hidden Subgroup Problem via Quantum Fourier Sampling (QFS) for the symmetric group…
The Complexity of the Local Hamiltonian Problem
Julia Kempe, Alexei Kitaev, Oded Regev
The k-local Hamiltonian problem is a natural complete problem for the complexity class QMA, the quantum analog of NP. It is similar in spirit to MAX-k-SAT, which is NP-complete for…
Quantum Color-Coding Is Better
Joshua Von Korff, Julia Kempe
We describe a quantum scheme to ``color-code'' a set of objects in order to record which one is which. In the classical case, N distinct colors are required to color-code N objects…
Coins Make Quantum Walks Faster
Andris Ambainis, Julia Kempe, Alexander Rivosh
We show how to search N items arranged on a grid in time , using a discrete time quantum walk. This result for the first time exhibits a…
