A first of his kind, the workshop “Use-cases from quantum technologies for sensing and metrology” aims to explore the use-cases from quantum technologies for sensing and metrology applications. The chosen method is based on a prospective analysis associating quantum technology experts, and technology prescribers in their field (research, industry or market), able to define the relevant performances, needs and ultimately markets.

Six technology areas will be considered, covering both use cases in research (may involve high-tech industry, or academia), where the highest performances are targeted, where the market sizes can be small and the cost may play a secondary role, and use cases for the end-user, where the typical market sizes are very large, the costs have to be low and the device sizes have (often) to be small. These areas are:

• Quantum enhanced magnetometry
• Gravimeters
• Detecting microwave radiations, and applications
• Detecting radiation at single photon level, and applications
• Time references
• Quantum enhanced interferometry, and applications

Be at the forefront of thinking about the impact of quantum technologies on sensors and metrology!

December 10-11, 2018 – Institut Néel (Grenoble, France).

We are pleased to announce the 7th European Frequency and Time Seminar (EFTS), Besancon, France, July 1-5, 2019.

The EFTS is an intensive full-week seminar intended to provide education and training with lectures and laboratory sessions. It targets a broad audience: Engineers, Ph.D. Students, Post-doc Fellows, Young Scientists, Newcomers, etc.

This seminar is original in the following:
· Broad spectrum of topics related to time and frequency
· Broad target audience, yet keeping high level education
· Balance between academic and applied issues
· True laboratory sessions (as opposite to demos). The attendees are expected to practice on a wide range of instruments made available.

At the 2019 EFTS, we plan 23 lectures, 12 H labs in small groups, visits at the Femto-ST Institute and the Observatory of Besancon, social events, and an Astronomy Session on the “exact time” from stars.

Registrations will only open at the end of January. However, pre-registrations (no invoice issued) are welcome.

Detailed program and Abstracts are being prepared, and will be available later. In the meanwhile, you can download the Abstracts of the previous edition.

Abstract: This thesis is part of the research and development of surface elastic wave components for the harsh environments exceeding 600°C. The objective is the realization of surface elastic waves self-encapsulated components which can reach a temperature of 900 ° C. In this work, we introduce a modulization method allowing a finite element finite resolution of an inhomogeneous bias. This method allows to directly calculate the bias problem and to extract the parameters calculated with the perturbation method as well as other parameters. This method contributes to the improvement of the realism of numerical simulations of structures subjected to wide variations of environmental parameters. We describe in this manuscript the approach of the study, the design, the realization and the tests of unencapsulated surface wave resonators for air annealing cycles up to 900 ° C as well as a bench of measurements allowing to perform the measurements in situ. We also discuss the design and implementation of the encapsulation of these resonators by an innovative technology by Wafer-Level Packaging for high temperatures.

The 26th General Conference on Weights and Measures (CGPM) will take place in Versailles in November 2018. At this meeting, we expect the CGPM to approve a resolution to revise the definitions of the International System of Units, the SI, which is based on the second, the metre, the kilogram, the ampere, the kelvin, the mole and the candela (the SI base units).

Over the last 50 years, scientists have measured constants of nature, such as the speed of light and the Planck constant, with increasing accuracy; indeed the metre was already redefined back in 1983 in terms of the speed of light. The inherent stability of these constants make them ideal for underpinning new definitions of the SI units and preparing the measurement system to meet the future demands of science and technology.

If the resolution is approved, the SI will be based on seven physical constants, and thus inherently stable. Most notably, this will mark the end of the last remaining physical artefact in the SI system – a cylinder of metal known as the International Prototype of the Kilogram.

The work needed to reach this point has taken many years, and has been a truly international effort. The universality of access that it will afford has been a long-standing goal for the metric system, dating back more than 200 years.

L’émergence d’une métrologie quantique a permis de rattacher toutes les unités de base à des constantes fondamentales de la physique. Un nouveau système d’unités a donc été proposé à la Conférence Générale des Poids et Mesures de novembre 2018 qui supprime en particulier le kilogramme étalon matériel des unités de base. Cette évolution permet de garantir une universalité, une pérennité et une meilleure reproductibilité des mesures. Le choix des constantes va assurer une cohérence au nouveau système fondé essentiellement sur les progrès de l’interférométrie atomique et de la métrologie électrique quantique. Les développements de ces disciplines et leurs applications en métrologie seront discutés au cours de cette séance.

Conférence-débat de l’Académie des sciences, le 4 décembre 2018 de 14h30 à 16h45, dans la Grande salle des séances de l’Institut de France : “Le nouveau système international d’unités (SI) fondé sur un choix de constantes physiques fondamentales”.

The Workshop on Synchronization and Timing Systems (WSTS) is approaching 30 years of bringing together leading experts to discuss the latest timing and synchronization topics. Over this period, time synchronization has evolved from a niche application to an underpinning technology across Power, Telecommunication, Finance and many other industries and applications.

WSTS has tracked and helped the evolution of precision timing over these decades. This has allowed experts to meet and offers the opportunity to explore cross-industry innovation, as an array of timing technologies become increasingly essential to many sectors.

We particularly welcome presentations offered by the users of synchronization, especially new innovations/applications which provide an important perspective on the needs for timing and on related challenges.

For submitting a Presentation abstract, you will find that we seek either those that are relevant to a specific sector or technology area, and those that are sector independent.

Sector-related talks must choose:

• Telecom (e.g., 5G)
• Electric Grid/Power Industry
• Financial Services
• Transportation/Automotive
• Cyber-Physical Systems (Industrial Internet, Factory Automation, Computing,
  Sensor Data Fusion)
• Broadcasting and Multi-Media
• Other

For sector independent talks choose:

• Sources of Timing: GNSS, Network Links, Oscillators (Atomic, Qu, MEMS, Other)
• Timing Security/ Assured Timing
• Measurement/ System Validation
• Other

Presenting at this event positions your ideas in front of the top professionals in the timing and sync community. Please submit an abstract no later than Friday, October 5, 2018, to have your concepts considered.
