Quantum Discord Brains

Filed under: Uncategorized — rrtucci @ 5:59 pm

Of course, my blog on quantum computing would not be complete without a post on quantum discord. So here it goes:

They number in the hundreds and make a lot of noise.

They hate quantum entanglement because they say it is too taxing for their brains. “Too hard. Doesn’t taste good”, they say.

They appear to be involved in deep conversation with each other about an important scientific subject. “Quantum discord brains taste better than quantum entanglement brains”, they cry.

I for one can’t understand what they are saying. Their conversation sounds to me like simply a series of grunts and moans, punctuated by an occassional wistful cry of either:

“Let’s eat more quantum discord brains”

“Quantum discord brains is a unique quantum resource”

“We don’t need to eat no stinking quantum computing algorithms. Quantum discord brains is all the nutrition we need”

“Let’s meet at Vlatko Vedral’s home. He good zombie leader. He set up 2012 quantum discord zombie jamboree for us”.

I left my heart in San Francisco“. “I left my brain in Singapore CQT” is a popular song among zombies.


The Quantum Discord Zombie Hordes are upon us. This would make a good poster for a quantum computing algorithms or a quantum entanglement conference. (I’m not the painter of this awesome drawing. I’m not sure of its provenance)



  1. Almost seems to as if you don’t like the Quantum Discord research. 🙂

  2. The zombies ate the “me” that was supposed to be the fourth word in my previous comment. Blimey! The zombies must have already gotten to my brain.

  3. […] Quantum Discord research that is quite en vogue these days. It has recently been taken to task on R.R. Tucci's blog. Ironically, amongst many other aspects, it seem to me that Kingsley's approach may be rather […]

  4. Oxford University professor Vlatko Vedral has his own Wikipedia page and a personal website pointing out all the prizes he has received


    However, I think the Amazon.com reviews of his book “Decoding Reality” are a more truthful portrayal of his abilities as a physicist. Take a look at the ones with 1 and 2 stars if you want a good laugh. Even better, judge the book for yourself: read some pages from it next time you are at the book store or library. In my opinion, the book is verbose and not very coherent, not very original or deep or even correct in its physical insights. The author’s vanity permeates the entire book. Sometimes gifted people are vain, but this is not one of those cases.

  5. Actually started a Wikipedia stub on Kingsley a while back because it rubbed me the wrong way that they have articles on two rugby players with the same name. To me if you worked at a certain academic level and have a publishing record to show for it, you should be regarded as no less noteworthy than some professional league sport dudes. Alas, that’s not the criteria that Wikipedia uses. Other articles on some of my favorites such as Mendel Sachs are also facing deletion requests. Really don’t understand the point, as long as the articles are factually correct and objectively written.

    Once watched this Vlatko guy’s talk for about 5 min in a youtube interview about his book. 5 min of my life I will never get back.
