Club Meeting 11/08: Dr. Katherine Brown
On Nov 8, Dr. Katherine Brown will give a talk in the journal club.
Title:
Multi-dimensional Systems in Quantum Logic
Articles:
Simplifying quantum logic using higher-dimensional Hilbert Spaces
B.P. Lanyon et al.
Nature Physics 5, 134-140 (2009)
Adding Control to arbitrary unknown quantum operations
X.Q. Zhou et al.
arXiv:1006.2670v2
(Nature Communications 2, Article number: 413)
Abstract:
Standard quantum computing circuits using qubits, two dimensional quantum systems in order to create logic gates. In these two papers the authors show that using higher-dimensional systems, it is possible to perform the necessary quantum logic gates in a far simpler fashion, requiring simpler gates, and less of these gates. In my talk I will highlight the results of these papers and explain where their efficiency savings come from, and the limits of recreating the results in terms of qubits.
Time: 11/08/2011 4-5pm
Location: Rm 262 Nicholson
