Andrew White from the quantum technology laboratory at the University of Queensland, Australia, maintains an excellent web page listing conferences related to quantum technology around the world. You can find his most recent listing for 2018 conferences here and the listing for 2019 conferences here.
In addition to the conferences shown on the list mentioned above, here are some additional conferences:
The Quantum for Business (Q2B) conference will be held on December 10-12, 2018 at the Computer History Museum in Mountain View, California. Additional details and agenda will be posted on their web site here.
A half-day seminar on The Frontier of Quantum Computing will be held on December 14, 2018 at the Rotman School of Management at the University of Toronto. There will be talks on hardware implementations including quantum annealing and universal gate-model quantum computers as well as talks on applications including machine learning, quantum chemistry, material discovery, and others. The event will be co-hosted by the Creative Destruction Lab and the TD Management Data and Analysis Lab at Rotman.
The next meeting of the Warsaw Quantum Computing Group will be on Monday, December 17, 2018, at 7pm in Warsaw, in the “Przestrzen from Facebook” https://przestrzen.fb.com. The lecture will be given by Piotr Gawron and Przemysław Sadowski from the Quantum Systems of Informatics Group of the Institute of Theoretical and Applied Informatics, Polish Academy of Sciences. The title is “Elements of quantum machine learning”, the event’s webpage: https://www.facebook.com/events/262536561095838.
A workshop on Quantum Computing and High Performance Computing will be held on December 18, 2018 in Bolgna, Italy. The aim of the workshop is to bring together active and interested people in Quantum Computation as a near future perspective for High Performance Computing. Participants are expected to come from different Italian Universities and Research Institutes in different fields as well as from commercial companies. It is sponsored by Cineca, a consortium made up of 70 Italian universities, 5 Italian Research Institutions and the Italian Ministry of Education.
The Quantum Information Processing (QIP 2019) conference will be held from January 14 to 18, 2019 at the University of Colorado Boulder in Boulder, Colorado, USA, with tutorials taking place on January 12 and 13. It is the twenty-second international conference on theoretical aspects of quantum computing, quantum cryptography, and quantum information in a series that started in 1998.
The European Quantum Technologies Conference (EQTC) 2019 will be held in Grenoble, France from February 18th – 22nd, 2019. More details on the conference will be posted at their website here.
The Future of Quantum Computing, Quantum Cryptography, and Quantum Sensors summit will be held on March 19-21, 2019 in Boston, Massachusetts. The summit will offer comprehensive insights into the commercial future of all areas of quantum technology presenting the opportunities available today and future applications in business and government. It will have over 30 expert speakers from the commercial, end-user, start-up, governmental and academic organizations. Attendees will learn about the latest quantum technology opportunities in areas such as financial services, pharma and specialty chemical, healthcare, automotive and transportation, defense, government and R&D.
First International Workshop on Quantum Technology and Optimization Problems (QTOP’19) will be held in Munich, Germany on March 18-21, 2019. This workshop will explore the opportunities for the application of quantum technology and optimization problems in networked systems and will connect people from academia and industry to discuss about theory, technology and applications in order to exchange ideas in the areas of quantum technology and optimization problems in networked systems.
Quantum Information and Measurement (QIM) V: Quantum Technologies sponsored by The Optical Society (OSA) will be held on April 4-6, 2019 in Rome, Italy. The conference topics will cover the latest in theoretical developments and experimental implementations of quantum information technology, including the advanced engineering needed to realize such technologies. In addition to the conference’s traditional focus on quantum optics and photonics, the fifth QIM conference will also include other platforms for quantum technologies, broadly construed, including topics such as solid state systems (superconductors, semi-conductors), atoms and ions (including gravity gradiometers and gyroscopes, and computing and simulation engines).
