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 International Conference on Quantum Computing (ICoQC) will take place at Ecole Normale Supérieure in Paris, France from the 26th to the 30th of November, 2018. It will present an up to date perspective on the thriving field of quantum computing. The scientific program will combine invited tutorial talks by prominent specialists, contributed talks, poster presentations and a round-table discussion. The conference is organized jointly by the French network SIRTEQ (Science and Engineering in Ile de France for Quantum Technologies) and the CEA, and sponsored by ATOS. Click here for details.
The Q-Turn workshop is a new, international, quantum information workshop that aims to bring together the leading researchers in the areas of quantum computation, information and foundations. It will be held November 26-30, 2018 in Florianópolis, Brazil. Topics covered will include: quantum information (e.g. cryptography, error correction, tomography, entanglement theory, many-body theory); quantum foundations (e.g. correlations, causality, generalized probabilistic theories, quantum thermodynamics, quantum gravity); quantum computation (e.g. simulation, algorithms, quantum complexity theory). Sponsors include ETH Zürich, FQXi, IQOQI Vienna, Microsoft, IQC, and Freie Universität Berlin.
The Future of Quantum Businesses event hosted by Hello Tomorrow Switzerland will occur on November 27, 2018 in Geneva, Switzerland. The event will include early-stage science-startup founders, executives, journalists & investors to discuss bringing quantum advantages to businesses, demystifying the hype for corporates and investors, inspire and pushing forward quantum entrepreneurs/businesses.
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.
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.
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).
