A selection of quantum conferences that may be of interest:   131 meetings and counting...

Note. 23 meetings were held in January and February; from March onwards 81 meetings have been cancelled, postponed, or moved online due to COVID-19. Please let me know if you know of others not yet listed here.

Junk conference warning

In modern science, as any field matures it becomes a target of predatory journals, publishers §, and meeting organisers: quantum technology is no exception unfortunately! For those interested in the sociology of this, the New York Times has a nice recent article: A Peek Inside the Strange World of Fake Academia; also see this HuffPost article, Predatory Conferences Undermine Science And Scam Academics; and this great blog post from Derek Lowe, Cutting Back On Lousy Conferences.
(§ Another good resource is the resurrected Beall's list of predatory journals and publishers).

Regular readers of this page have reported the following conferences as junk conferences, based on attending and/or presenting at earlier incarnations of them.

BIT Congress are a known predatory publisher, who "...is part of a wave of organizations that have appeared in China in past several years noted for arranging congresses with little academic merit and with the primary aim of generating revenue rather than scientific knowledge sharing." Here is the list of conferences to avoid.

EMN. Social media has lit up with colleagues complaining about spam from an organisation called EMN Meetings—mostly on private pages, but here are representative public postings by Jacob Biamonte and Heino Falke. Here is the list of conferences to avoid.

OMICS are a known predatory publisher, who "...started publishing its first journal in 2008. By 2015, it claimed over 700 journals, although about half of them were defunct". They run conferences that rarely—if ever!— have organisers from the field, or indeed reputable speakers. Note the URL for these conferences can be either omicsonline.org or conferenceseries.com. Either way, here is the list of conferences to avoid.
UPDATE: OMICS has been fined $50M for deceptive practices.

Oscine are a new entrant on this list, with the classic hallmarks of a predatory publisher and conference organiser. Here is the list of conferences to avoid.

Phronesis are another new entrant on this list, again with the classic hallmarks of a predatory publisher and conference organiser. Here is the list of conferences to avoid.

Scientific Federation are yet another new entrant on this list, with the classic hallmarks of a predatory publisher and conference organiser. Here is the list of conferences to avoid. Note in particular they have set up an ICAP predator:

It has come to our attention that a likely predatory conference, with a name, date and country of venue close to ICAP, is sending notices to members of our community. "IAMOP-2020, the 3rd International Conference on Atomic, Molecular and Optical Physics," is (supposedly) to be held in Montreal Canada in July 2020. This meeting is completely unrelated to ICAP 2020 (the 27th International Conference on Atomic Physics), which will be held 19-24 July 2020, in Toronto, Canada. Please also be vigilant about fraudulent housing offers from similar organizations.
Any information about ICAP 2020 will be distributed through this mailing list, so should be from icap2020@listserv.physics.utoronto.ca. If you have any doubts about a mailing you receive, feel free to contact the conference secretariat at icap2020@physics.utoronto.ca, or visit our web site (icap2020.com), where the invited program will be announced in the fall, and information on accommodation and registration will be available early next year.
best regards, Michal Bajcsy, Gordon Drake, and Joseph Thywissen, co-chairs of ICAP 2020

waset are a known predatory publisher, run by a former science teacher in Turkey (and his family). Readers have complained to this site about their fraudulent behaviour, for example:

I would also like to alert you that this particular organization has been using my name as their conference committee member. I am not involved at all with this organization and their conferences and have not consented for my name to be used. My university legal office has been informed and is looking into the matter. I hope you will inform your colleagues if they happen to associate me with these conferences."—Kim Guan Saw, 2 April 2015

See the comments at the end of this post for other experiences; or this warning. Comments from the former include:

In 2012 I organised an international conference ... our list of working group titles has just been copied and pasted for a WASET conference (15–16 May 2013)
The conference is a complete scam. I know I have been on several hiring committees and if we see someone list a paper published at WASET on their CV we immediately stop evaluating their application.
I went to a WASET conference and it was a complete joke. There were virtually no people there in my field, and the talks were completely unrelated to each other. Basically each person got up and spoke about their work to a completely unrelated audience. For example, the person before me talked about boat design, I talked about quantum mechanics, and the person after talked about Halal meat!

Here is the list of conferences to avoid.
