[quantum-info] Today's PIQuDos

[Markus Mueller]

Hi all,

this is a reminder of Oliver Gray's talk today at 4 pm in the Time Room.


Title: *Efficient distributed quantum computing*
Speaker: *Oliver Gray* (University of Bristol)

Abstract:
I will explain how to simulate arbitrary quantum circuits on a 
distributed quantum computer (DQC), in which the pairs of qubits that 
are allowed to interact are restricted to the edges of some (connected) 
graph G.  Even for graphs with only a modest number of long-range qubit 
interactions, such as the hypercube, this simulation is, in fact, 
efficient.  Furthermore, for all graphs, the emulation scheme is very 
close to being optimal.
Secondly I will present an efficient quantum algorithm for parallel 
unrestricted memory look-up.  As an application, I will show that the 
space-time trade off for Element Distinctness and Collision Finding can 
be improved.
Both results arise from applying the ideas of reversible sorting 
networks to quantum computing.
