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 2020 conferences here.

In addition to the conferences shown on the list mentioned above, here are some additional conferences:

Harrisburg University is hosting a Quantumpalooza 2020 sessions for four separate weeks beginning May 18, May 25, June 1, and June 8. It is the first of an annual event where learners can  ‘binge’ on free lectures, seminars, and workshops presented by experts  from Harrisburg University, across the United States, and Europe. Follow this link for more information and to register  for any of the free sessions. Quantumapalooza is co-hosted by the  Philadelphia/Harrisburg Quantum Computing Meetup group, which is funded by Harrisburg University.

Inside Quantum Technology – New York, The Future of Quantum Computing, Quantum Cryptography and Quantum Sensors has been changed to an online conference that will occur on June 1-5, 2020. This event is intended for business people and professionals in the quantum technology field who want to keep track of all relevant information to make strategic choices. It will provide comprehensive insights into the commercial future of all areas of quantum technology, presenting both opportunities available today and future applications for businesses and government. Presentations will be archived for those wishing to view them at a later date.

Quantum.Tech Digital Week will occur from June 12 to June 19, 2020.  This will be an online event and the session on June 12 will be a Startup and Investor Showcase.  And then from June 15-19, 2020 there will be online presentations with a purpose to drive forward the commercialization of quantum applications across industry. Topics will include current status of quantum computing, evaluation of different architectures, machine learning; optimization; simulation, international perspectives and investment, sensing & metrology applications, communications & cryptography, across QKD, PQC and RNG, and preparing a quantum ready organization.

A Quantum Information Science & Technology Summit has been postponed until September 2020 with a specific date to be determined soon.  It will be held at the New York Academy of Sciences in New York City. This summit is organized by the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory as part of DOE’s InnovationXLab series.  It will connect leaders in the finance and banking, technology, communications, energy and materials sciences sectors to discuss how to accelerate Quantum Information Science & Technology (QIST) advancements that impact the nation and world.

The EPIC World Industrial Quantum Photonics Technology Summit will be held at the University of Glasgow in Glasgow, UK on September 3-4, 2020. The purpose of the summit is to bring together companies in the supply chain for five product ranges including quantum clocks, quantum imaging, quantum sensors, quantum computers and quantum communications networks.

The 9th annual Adiabatic Quantum Computing Conference (AQC 2020) has been cancelled.  Instead AQC 2020 will coincide with a conference on Quantum Annealing / Adiabatic Quantum Computing at the International Center for Theoretical Physics in Trieste, Italy, to be held on September 7-11, 2020.

The conference on Quantum Annealing / Adiabatic Quantum Computing will be held at the International Center for Theoretical Physics in Trieste, Italy on September 7-11, 2020. The conference will deal with academic and basic research on quantum annealing and adiabatic quantum computation with a broad focus including quantum approximate optimization (QAOA) and other variational quantum approaches and in close connection with the neighboring fields of Quantum Simulations and Quantum Computation.

The Quantum Technology International Conference 2020 (QTech 2020) will be held in Barcelona, Spain on November 2-4, 2020. The objectives of the conference is to present the latest developments of quantum technologies in the domains of quantum communication, computation, simulation, sensors and metrology, and their implementation using various platforms from atoms and ions to solid states, superconducting circuits and optics.

The IQT Europe 2020 conference will be held at The Hague Conference Center in the Netherlands on November 9-11, 2020.  The conference will be produced by Inside Quantum Technologies, QuTech and 3DR Holdings and will be their second annual European conference. Details and a link to the website will be posted at a later date.

The IEEE Quantum Week, also known as the IEEE International Conference on Quantum Computing and Engineering (QCE) will be held in Broomfield, Colorado on October 12-16, 2020. This conference aims to bring together quantum professionals, researchers, educators, entrepreneurs, champions and enthusiasts to exchange and share their experiences, challenges, research results, innovations, applications, pathways and enthusiasm on all aspects of quantum computing, engineering and technologies.

The Second European Quantum Technology Conference (EQTC) will be held in Dublin, Ireland on November 23-27, 2020.  This will be a follow-on to the first EQTC conference held in Grenoble, France in 2019. EQTC 2020 will provide full coverage of the most prominent and recent advances in European and International quantum technology activities across basic sciences, communication, computing, simulation and sensing/metrology. The conference program addresses a wide range of topics in quantum technologies including fundamental science, infrastructure development, industry engagements, education & training, encouraging and facilitating gender balance in the quantum community, international cooperation, and policy-making. It will provide a forum to highlight the state-of-the-art in quantum technologies both in Europe and from around the world.

The fourth annual Q2B Conference presented by QCWare will be held in Silicon Valley, California on December 8-10, 2020.  Details and a link to the website will be posted at a later date.
