Dear Alexander,

This result appeared in [**last year's**][1] QIP. My review is for a journal.

I agree that posting reviews publicly can influence other reviewers, which might be a problem. However, I think it is unlikely in this particular case (I don't know how many reminders a typical review

...(continued)

The Platypus speaks of "publication", so maybe he/she is just a reviewer for a journal? Besides the submission to the journal, the paper could be submitted to a number of conferences (even beyond QIP): should the Platypus wait for a minimum amount of time (1 year from submission to the arXiv? more?)

...(continued)

Perplexed Platypus, don't you know that other reviewers should not see your review beforehand? Couldn't you wait until after the list of accepted papers for QIP is out there?

This work provides new constructions of unitary 2-designs that are exactly implementable with a nearly linear number of quantum gates. These constructions rely on unitaries from the Clifford group to mix Pauli matrices. Typically Clifford unitaries are represented by $2n \times 2n$ symplectic transf

Apologies for the delayed reply.

No worries with regards to the code - when it does get released, would you mind pinging me? You can find me on [GitHub](https://github.com/Travis-S).

I believe this work should mention the paper of Griffiths et al, "Atemporal diagrams for quantum circuits", PRA 73, 052309 (2006) http://journals.aps.org/pra/abstract/10.1103/PhysRevA.73.052309, arXiv:quant-ph/0507215 http://arxiv.org/abs/quant-ph/0507215. It is similar in flavour.

A new version is updated.

Hi Travis

Yes, that code is related to the work we did and that is my repo. However it is quite outdated. I used that repo for sharing the code with my collaborators. Now we are working for providing a human friendly version, commented and possibly optimized. If you would like to have a working

We noticed that our theorem 2 is the same as theorem 2 in http://journals.aps.org/pra/abstract/10.1103/PhysRevA.80.052306. We will revise our draft accordingly.

Thank you for the kind comments, I'm glad that our paper, source code, and tutorial are useful!

Has anyone found some source code for the SGD referenced in this paper? I came across a [GitHub repository](https://github.com/nicaiola/thesisproject) from Nicola Pancotti (at least, I think that is his username, and the code seems to fit with the kind of work described in the paper!). I am not sure

This was a really well-written paper! Am very glad to see this kind of work being done.

In addition, the openness about source code is refreshing. By explicitly relating the work to [QInfer](https://github.com/csferrie/python-qinfer), this paper makes it more easy to check the authors' work. Furthe

I can only quote Derrick Stolee: 'Terry Tao just dropped a bomb'. :)

Ha!

Great Acknowledgements.

As a quick addendum, please note that the [supplementary video](https://www.youtube.com/watch?v=22ejRV0Kx2g) for this work is available [on YouTube](https://www.youtube.com/watch?v=22ejRV0Kx2g). Thank you!

Very interesting! After looking a bit more into this, it seems like there are actually quite a few websites with such functionality. Most notably, [Publons][1] where reviewers can post their reviews publicly as well as get credit for them.

[1]: https://publons.com/

The last site in your comment [PubPeer][1] seems to be a good place to have open research discussions online. There is an intense discussion about this paper there already.

By the way, this PubPeer site has an option that could be interesting to have in SciRate as well: one can review papers and/o

@John Bryden. Could you use quotes "" or bloquotes > when citing? It improves readability and avoids potential misunderstandings.

Note that it's not possible to submit papers to SciRate directly; this site simply aggregates information from other sites. However, I've added an issue relating to potentially marking withdrawn papers - https://github.com/scirate/scirate/issues/318.

Aside from the comment above there are other comments that should be made.

A very important comment is this. The fraudulent paper of Ntatin, is quite simply NOT correct.
By this I mean the following: In 1999 Florian Deloup and I began a project that we called "The linking form conjecture for 3-m

This article submitted by B. Ntatin and W. Glunt was published in a new Journal called Advances in Pure Mathematics (APM for short) in September of 2013. In July 2014 the Journal APM RETRACTED this article. The reason that APM retracted this article to quote the Journal is :

Dear Referee,

I found your suggestion of exploring search on a weighted graph to be interesting, so I worked it out with one marked vertex: https://scirate.com/arxiv/1507.07590

Besides the speedup, the new methods are important; I extended degenerate perturbation theory in a couple ways that s

Sorry. Is it just quantum contextuality?

fyi: our quantum implications are presented in Subsection 2.2 (pp 7-9).

Dear Tom,

Thank you again for engaging in this conversation. It definitely helped me to understand your paper and your point of view much better and hence provide a more accurate review. Unfortunately, not all of your arguments were convincing to me. Even though they improved my understanding, th

I am no expert at all on strongly correlated systems or topological order, but since you refer to information theory in your abstract, let me still ask you: What is the justification for using $I_2(A:B) = H_2(A) + H_2(B) - H_2(AB)$ for the Rényi mutual information? This quantity has no information-t

Dear Perplexed Platypus,

Thanks for taking the extra effort to engage with me during the review process, and I'm glad that we see more similarly now. I hope you don't mind me clarifying a little more, since it may also help others. Feel free to ignore my comments below since you need to wrap up t

Dear Tom,

Thanks again for responding to my comments, I understand your point of view much better now.

I guess they just enabled it. I got a bunch of emails about these comments all at once.

It seems that email notifications of comments still doesn't work, as was discussed by Perplexed Platypus, Ashley Montenaro, and Aram Harrow (https://scirate.com/arxiv/1408.1816#456). Perhaps this should be added to the project's GitHub issue list? Or are they already working on it?

Dear Perplexed Platypus,

>Thanks a lot for your prompt response and also for engaging in this experiment to asses whether SciRate can be a feasible platform for reviewing papers publicly while engaging with the authors during the process.

You're welcome. I appreciate the opportunity to discuss

You can always make suggestions on the GitHub project pages' [issue list](https://github.com/scirate/scirate/issues). I've included this one here: https://github.com/scirate/scirate/issues/315.

I agree and I might do that in the future. However, for the time being I prefer to have a single identity, otherwise it can get confusing which platypus is which...

p.s. It might be useful to have a "meta" thread in SciRate where people can discuss matters that are not related to a particular art

@Perplexed Platypus: I like your experiment of reviewing papers on SciRate. To ensure single-blindness of the reviewing process I'd recommend using a *new* anonymous account every time you review a new paper.

Dear Tom,

Thanks a lot for your prompt response and also for engaging in this experiment to asses whether SciRate can be a feasible platform for reviewing papers publicly while engaging with the authors during the process.

I agree that adjacency matrix and Laplacian are two natural choices of

Dear Referee,

Thank you for taking the time to carefully referee the manuscript. I appreciate your organized response and the opportunity to clarify the motivations and results. First, let me respond to your two main points:

**Summary**

This paper investigates continuous-time quantum search on a graph with several marked vertices. Using a specific family of graphs, it is shown that different marked vertex configurations can lead to different optimal choices of parameters in the Hamiltonian governing the walk, and thu

This paper "**Tree-based convolution for sentence modeling**" is a deliberate plagiarism. The texts, models and ideas overlap significantly with previous work on arXiv.

There's also a [docker image](http://ryankennedy.io/running-the-deep-dream/) if you want to play with it, though if you're on Linux or OS X you might want to install everything natively in order to get GPU acceleration (the gradient ascent can be quite slow on higher layers in the network)

The image recognition model described here is the one responsible for [deepdream](http://github.com/google/deepdream).

Wow, impressive. Very impressive.

I like the word FORANDLATION: it's a corruption of a corruption of the word "correlation".

Interesting comment at the bottom of page 9... :)

This article contains new results concerning the stroboscopic tomography, the aim of which is to reconstruct the initial density matrix on the basis of the least possible amount of data. The author proposes one complete quantum tomography model, which shows how step by step you can obtain the formul

Thanks for the comment! This is a good idea, I will do that in the next arXiv version.

Wonderful! I've been waiting for a book like this for a while now! Thanks, Marco.

I do have one trivial comment from a 30 second preliminary scan, though: please consider typesetting the proofs with a font size matching the main text. If us readers are already squinting hard trying to understand

The authors will want to look at work that Simone Teufel has done, in particular her Argumentative Zoning, which discusses the stance that the paper author takes with respect to the citations in that paper.

This article has generated a fair bit of discussion. But I found a few of the statements puzzling (Edgar Lozano also). Take for example, Theorem 1 (ii) (reversibility) which appears to contradict a number of previous results. Should we understand your work function as "work in the paradigm where we
