1st Quantum Artificial Intelligence Execution

A friend, Craig R., sent out a link to a /. posting about the article First Demonstration Of Artificial Intelligence On A Quantum Computer. This is one of the most interesting articles on QIP that I've seen thus far. Basically a team of Chinese physicists lead by Zhaokai Li built a (get this) non-AQC model for to do quantum AI computation. Their QC model is based on the Support Vector Machine or VSM; they've aptly named it QVSM. The actual "quantum machine" is a 4 qubit quantum processor base on the nuclear magnetic resonance (NMR) technique.

Interestingly the Hamiltonian is expressed as a weakly-coupled spin system and the format is an ising-like Hamiltonian

$$ H_{NMR} = \sum_{j=1}^{4} \pi v_j \sigma_{z}^{j} + \sum_{1 \le j < k \le 4} \frac{\pi}{2} J_{jk}\sigma_{z}^{j} \sigma_{z}^{k} $$

Remarkably the result was quite interesting:

They've put their paper on the arXiv: arxiv.org/abs/1410.1054.
