Exponential algorithmic speedup by quantum walk
Andrew M. Childs, Richard Cleve, Enrico Deotto +3
We construct an oracular (i.e., black box) problem that can be solved exponentially faster on a quantum computer than on a classical computer. The quantum algorithm is based on a c…
Microscopic Structure of a Vortex Line in a Superfluid Fermi Gas
N. Nygaard, G. M. Bruun, C. W. Clark +1
The microscopic properties of a single vortex in a dilute superfluid Fermi gas at zero temperature are examined within the framework of self-consistent Bogoliubov-de Gennes theory.…
Combinatorics and Quantum Nonlocality
Harry Buhrman, Peter Hoyer, Serge Massar +1
We use techniques for lower bounds on communication to derive necessary conditions (in terms of detector efficiency or amount of super-luminal communication) for being able to repr…
One-dimensional quantum walks with absorbing boundaries
Eric Bach, Susan Coppersmith, Marcel Paz Goldschen +2
In this paper we analyze the behavior of quantum random walks. In particular we present several new results for the absorption probabilities in systems with both one and two absorb…
