Making Quantum Technology Ready for Industry
Brussels 28/29 March 2019 Making Quantum Technology ready for Industry Putting Science Into Standards (PSIS) Workshop on Quantum Technology CEN-CENELEC Management Centre Rue de la Science 23, 1040-Brussels www.cencenelec.eu www.ec.europa.eu/jrc/en #Standards4Quantum Workshop structure On 28th and 29th of March 2019, the Joint Research Centre and CEN/CENELEC hold at the CEN/ CENELEC Management Centre (CCMC) in rue de la Science 23, Brussels, a workshop titled Making Quantum Technology Ready for Industry. The workshop focuses on current standards and potential standardisation fields in quantum technologies and is organised with the support of the German Institute for Standardization (DIN) and DG CNECT, the host of the EU Quantum Flagship. In Europe, the European Telecommunications Standards Institute (ETSI) has established an Industry Specification Group with a specific focus on quantum key distribution (QKD). At the international level, standardization is taking place within Joint Technical Committee 1 of ISO/IEC addressing among others cybersecurity and data protection. CEN and CENELEC have signed agreements with ISO and IEC through which common European and international standards can be developed in parallel, thereby avoiding duplication of work Since many quantum technology areas are advancing on the technology readiness level scale, it is important to prepare the field for standardization activities, helping to facilitate and accelerate market uptake of quantum technology. The workshop provides: 1. an overview of how standardization can be useful to the quantum innovation process; 2. what standardizers can do for the quantum science community. To contribute to the different pace in the main quantum areas, the workshop is divided in four technical sessions. -

Quantum error correction codes, then, can be employed to diagnose and remove the possible errors in the quantum information, thereby avoiding the loss of information. Although a series of single- and two-qubit gates can be employed to construct a quan- tum error correcting circuit, however this decomposition approach is not practically desirable because it leads to circuits with long operation times. An alternative ap- proach to designing a fast quantum circuit is to design quantum gates that act on a multi-qubit gate. -

The Quantum Times
TThhee QQuuaannttuumm TTiimmeess APS Topical Group on Quantum Information, Concepts, and Computation autumn 2007 Volume 2, Number 3 Science Without Borders: Quantum Information in Iran This year the first International Iran Conference on Quantum Information (IICQI) – see http://iicqi.sharif.ir/ – was held at Kish Island in Iran 7-10 September 2007. The conference was sponsored by Sharif University of Technology and its affiliate Kish University, which was the local host of the conference, the Institute for Studies in Theoretical Physics and Mathematics (IPM), Hi-Tech Industries Center, Center for International Collaboration, Kish Free Zone Organization (KFZO) and The Center of Excellence In Complex System and Condensed Matter (CSCM). The high level of support was instrumental in supporting numerous foreign participants (one-quarter of the 98 registrants) and also in keeping the costs down for Iranian participants, and having the conference held at Kish Island meant that people from around the world could come without visas. The low cost for Iranians was important in making the Inside… conference a success. In contrast to typical conferences in most …you’ll find statements from of the world, Iranian faculty members and students do not have the candidates running for various much if any grant funding for conferences and travel and posts within our topical group. I therefore paid all or most of their own costs from their own extend my thanks and appreciation personal money, which meant that a low-cost meeting was to the candidates, who were under essential to encourage a high level of participation. On the plus a time-crunch, and Charles Bennett side, the attendees were extraordinarily committed to learning, and the rest of the Nominating discussing, and presenting work far beyond what I am used to at Committee for arranging the slate typical conferences: many participants came to talks prepared of candidates and collecting their and knowledgeable about the speaker's work, and the poster statements for the newsletter. -
