# Quantum Computing Logo

## Question Background

Recently in chat, Justin Youens pointed out that the current logo has little significance to the subject of Quantum Computing.

## The Question

What is the significance of the "square" logo?

## Proposal

Unless the above question has an answer, I think this StackExchange site could benefit from a more relevant logo. Relevant in regards to the field of quantum computation.

## Logo Ideas

If anyone has design ideas to share, please share them.

• I wouldn't go around interpreting it as an atom. I would however, go around interpreting it as a Bloch sphere (i.e. possible states of a single qubit), which is more relevant anyway :) – Mithrandir24601 Mar 23 '18 at 18:13
• I like the idea of a bloch sphere being the logo. Maybe not that specific design, as it could be confusing (Is it an eye? Or a bearded, eyeless man wearing a cap?) but something similar could probably work really well. – blalasaadri Mar 24 '18 at 22:51
• Yeah, to be clear it was intended to be an abstract Bloch sphere. We could add more detail, but keep in mind it has to work at a small (favicon, etc) size. – Justin Youens Mar 25 '18 at 19:29
• They made us a logo and have it live on the right column of other sites: physics.meta.stackexchange.com/questions/10394/… -- I really like @Blue 's suggestion of the Bloch sphere, this is what it looks like with annotations: quantumcomputing.stackexchange.com/a/1231/278 . – Rob Mar 26 '18 at 5:24
• Please post the logo idea as an answer so that the up/down votes on this thread make sense. – DanielSank Mar 26 '18 at 16:10
• @DanielSank That is exactly what I intended this thread to be - a suggestion thread for alternative logos. I updated the original post to reflect this idea. – Daniel Burkhart Mar 26 '18 at 21:43
• @DanielBurkhart yes but my point is that the logo in the OP should be in an answer. Meta posts that say "Let's discuss question Q. Here is my answer A" are troublesome because answer A cannot be easily voted on in the same way as answers posted by other users. – DanielSank Mar 26 '18 at 22:01
• @DanielSank I removed the image from my original post and added it as an answer (proposal in the context of this post). – Daniel Burkhart Mar 26 '18 at 22:13
• @DanielBurkhart nice. Thanks! – DanielSank Mar 26 '18 at 23:11
• what about something along these lines? (pun not intended) sciencedaily.com/images/2014/07/140714104103_1_540x360.jpg – fr_andres Apr 3 '18 at 1:33
• After literal years of discussion. What's the next step for changing the logo? – luciano Sep 26 '20 at 8:46

• This logo was created by Justin Youens. – Daniel Burkhart Mar 26 '18 at 22:16
• Was it? I thought it was made by the designer from Strangeworks. And that Justin is their programmer. – Discrete lizard Mar 28 '18 at 12:33
• Could someone create a re-scaled version for community ads? – Discrete lizard Mar 28 '18 at 12:34
• See below for a modified version of this idea. – Emilio Pisanty Apr 19 '18 at 10:11

Here is an alternative, in Community Ads format. It combines the colors of the existing cube thingammy with a stylized Bloch sphere and ket.

Sizes &c can be fine-tuned but I think the core idea improves and synthesizes on the existing designs.

The Inkscape source is available here if people want to tinker with it.

• I like this one: the Bloch sphere and ket are both relevant and match nicely. I also think this idea could even work as favicon: I think it would remain distinguishable enough. – Discrete lizard Apr 28 '18 at 10:55
• You probably want to thicken the lines of the ket bracket to make them more visible in a tiny favicon. – can-ned_food May 7 '18 at 5:00

Option #4

UPDATE:

Based on the conversation in the comments here are two new versions for review. @emiliopisanty @blue what do you think of these?

Option 4.2

Option 4.3

Let me know what you think.

Previous Text

Ok based in the feedback from Emilio Pisanty we modified the "c" in the original draft to stand upright. Here's the latest version:

Let me know if there are any additional changes the community would like to see this or any of the other logo drafts and we'll turn them around as fast as possible.

• This is gorgeous. I would suggest turning the inner C so that it's vertical (as in this one) while keeping the same Q. – Emilio Pisanty Sep 3 '18 at 9:28
• Thank you Emilio we will make the adjustment this week and post the revised version. – whurley Sep 3 '18 at 16:40
• Thanks again for the feedback Emilio, here is the revision based on your feedback. The original idea was to have the "C" revolving around the "Q" to bring a more active sense of superposition, something a little more dynamic than the straight vertical. However, based on your feedback we've created the updated version you see at the top of this post. What do you think about this one? – whurley Sep 3 '18 at 21:37
• @whurley This one looks great. +1 from my side :) Any idea by when we'll get the new logo implemented? – Sanchayan Dutta Sep 3 '18 at 21:40
• @whurley I was thinking more in terms of something like this, which is a straight rotation, though now that I see it, it probably needs a designer to work a bit more carefully on the angles on the ends of the C to make it work to its fullest potential. I liked v1 a bit better than the current v2, though. – Emilio Pisanty Sep 3 '18 at 22:02
• @EmilioPisanty checking into it now. – whurley Sep 4 '18 at 0:41
• @Blue that's all up to the community and the mods I'm just trying to help get something clean that the communtiy will like :) – whurley Sep 4 '18 at 0:42
• Option 4.3 looks perfect to me! Maybe we should wait for @EmilioPisanty's response though. – Sanchayan Dutta Sep 4 '18 at 18:05
• @Blue I dunno, the inner C's don't look quite as C-y as I imagine they could in the current iterations. I don't know why people are hanging on my opinion, though - I'm just another guy on the internet. – Emilio Pisanty Sep 4 '18 at 18:08
• @EmilioPisanty rofl now you know how I feel :) Hopefully, more people will chime in so we can make sure everyone feels included and the community is involved. Again, it's not like I can make the decision. Just trying to help make sure we have a high quality logo. – whurley Sep 4 '18 at 19:51
• This is exactly what I was hinting at with my lame design, thanks for the effort! I love it and agree with @EmilioPisanty's remarks – fr_andres Sep 1 '19 at 17:41

They have a specific format, copying that, your color scheme and adding a Bloch sphere I came up with:

The SVG came from: https://commons.wikimedia.org/wiki/File:Bloch_Sphere.svg#mw-jump-to-license .

No additional text is allowed in the submission, only include what is below this line.

• I am not sure, shouldn't the lines be a bit thicker? – MEE Mar 26 '18 at 7:34
• @MEE - Fixed? - I hand edited the SVG and tripled the stroke-width of every line. – Rob Mar 26 '18 at 16:05
• yes, seems to be a lot better – MEE Mar 26 '18 at 16:08
• This one looks busy to me, and not so easy to visually digest. It also focuses rather heavily on the Bloch sphere, which isn't really the essence of quantum computing. – DanielSank Mar 26 '18 at 16:11
• @DanielSank - You are welcome to make your own submission and upload it as an answer. I am not the "designer" so much as the one whom read the comments to the question and attempted to implement them. The main site has already put forth a proposal of what is thought we would want, if we don't come up with something then we get their design. – Rob Mar 26 '18 at 16:41
• @Rob I was simply voicing a comment on this post. I am aware that I can make separate posts. Commenting on this post and making my own are two completely orthogonal things. – DanielSank Mar 26 '18 at 22:02
• Looks great but wouldn't work in smaller (e.g. favicon) size. – DavidG Mar 27 '18 at 19:41

• We should high-light computing in our logo, as general quantum questions are off-topic. – Discrete lizard Apr 3 '18 at 12:10
• Thank you, I updated it now. – Vikram Palakurthi Apr 3 '18 at 14:50

Option #5

The context for this post is here

I hope it's not too late now to make suggestions for a logo. I agree with the others that the cube is unrelated to our topic. I had the following idea (which a designer could turn into some decent looking logo):

And on a dark background it should look like this:

And for the meta:

I could provide the svg source if anyone is interested. I think it's neat how it looks like a $\phi$, and of course it's supposed to look like a superposition of $|0\rangle$ and $|1\rangle$. So it's at least related to what we are doing!

• It is never too late for good ideas. I think the 0/1 in 'superposition' is a bit to complicated for a logo: I'd prefer Emilio Pisanty's Bloch sphere in the ket as a logo. However, when we get to the badges, I think this superposition idea might work: 0 for bronze, 1 for silver, 0/1 for gold. – Discrete lizard Apr 28 '18 at 10:55

Here my 2 cents: Inspired in the idea of superimposing symbols, which can be conceptually related to how quantum computing works as user James Wooton already did on this blog entry (not blaming you at all for my lame design!), I came up with the following concept:

It can work as small icon, and can also be mixed up with some other already exposed ideas to make it look more flashy and quantumy if needed. There is recent discussion about the similarity of the current logo to Amazon's AWS. Well, this looks similar to TensorFLow's logo, but I think that choosing different colors could help on that.

• The colors need be more distinct. As it is now, I almost cannot see anything other than a Q. – can-ned_food May 7 '18 at 5:02
• I agree! and also think that the font and other things should definitely be tweaked. I just hope it is visible enough to convey the concept – fr_andres May 9 '18 at 4:01

In an effort to help resolve the logo debate our own Justin Youens created, the Strangeworks team has looked over the chat, created some original ideas, advanced a few ideas from above (shout our to fr-andres superimposing symbols) and would like to submit the following as some possible candidates for the new community logo.

NOTE: We've kept them all colorless so decisions can be made on the design alone. Once the community pics one (or gives us the feedback to do revisions, start over, etc) we can do a color exploration and provide some color options.

I'm posting each option is being posted as a separate answer so people can upvote their favorite. Starting with option one being included in this post:

• You know, I really like them in grayscale... – MEE Sep 4 '18 at 18:26

Option #2

Option #3

The context for this post is here

There is a question in another answer about how it would look scaled to favicon size (32x32).

This is about as good it gets using a cellphone and the available tools.

That's the original source image from which the smaller size was derived.

That's the result of reducing it to 32x32 using a smart resizing algorithm (not simple scaling).

That's what it looks like with the Bloch sphere overlaid, lots of detail lost.

Converted to B&W, so it can be overlaid on to the greenish background.

The rules for submitting a design made no mention of developing a version for the icons used on the site, perhaps someone intends to take what is submitted and hand it over to a professional Graphics Designer (to preserve the Stack Exchange image and avoid sketchy looking sketches, along with providing some uniformity to the look).

If other people create a design there will likely be a better result and certainly more for people to vote on. That's what a sphere would look like, don't know what a cube had to do with QC; now we have both.
