Christian Kraglund Andersen, ETH Zürich

I started my studies at the Aarhus University in Denmark. I was always interested in exploring the boundaries of physics, and quantum computing sparked my interest as a real application that would take advantage of the peculiarities of quantum theory for
improved computational power. I therefore decided to continue my studies with a PhD in the group of Prof. Mølmer. As a topic
for my PhD, I studied new approaches for quantum optics and quantum computation with superconducting circuits. During my
PhD studies I spent 6 months at University of Sherbrooke, Canada, where I started a fruitful collaboration with Prof.
Alexandre Blais. After my PhD, I wanted to explore the real realizations of quantum computers and, thus, I pursued a postdoc
in the experimental laboratory of Prof. Andreas Wallraff at ETH Zurich, Switzerland. Since, the start of my postdoc, I have
become gradually more engaged in the practical realities of experimental quantum computing with superconducting circuits. I aim at understanding all aspects of quantum computing from the real- world experimental challenges to the high-level theoretical concepts of quantum information.

I obtained my master studies at Universidad Autónoma de Madrid in 2011.

In 2015, I completed my PhD studies in the experimental semiconductor group of Prof. Luis Viña (Dept. Physics of Materials, Univ. Autónoma de Madrid), on the applications and fundamental properties of exciton-polaritons.

In April 2015, I joined the group of Prof. Pascale Senellart, in the Laboratory of Photonics and Nanostructures (Marcoussis, France). During my postdoc, I worked on the realisation of efficient quantum photonic devices with quantum dots deterministically coupled to micropillar cavities. Using such devices, I generated a near-optimal emission of single indistinguishable photons and demonstrated a highly efficient light-matter interfacing operating at the single photon level.

In 2016, I received a Marie-Curie Individual Fellowship (SQUAPH) to research on: (i) the photonic scalability of quantum computing and (ii) the generation of photonic qubits and qutrits exploiting the quantum superposition in the photon number basis.

My current research interests are focused on quantum optical technologies based on solid- state single photon sources.

Brynle Barrett, iXblue

Brynle is a senior research & development scientist at iXblue—a French company that specializes in fiber-optic gyroscopes, inertial navigation and photonics—with expertise in quantum inertial sensors, atom optics and matter-wave interferometry. He received his BSc in physics and mathematics from Saint Mary’s University in Halifax in 2005. Following these studies, Brynle was awarded the Canada Graduate Scholarship to carry out his doctoral work at York University in Toronto. In 2012, he received his PhD in physics for his research on new experimental techniques in cold-atom interferometry and their application toward precision measurements of fundamental constants and inertial sensing. He was then awarded a post-doctoral research fellowship from the French space agency (CNES) to carry out research on a mobile dual-species interferometer and a new test of Einstein’s equivalence principle with cold atoms at the LP2N laboratory (Laboratoire Photonique, Numerique et Nanoscience) in Bordeaux, France. Since 2015, Brynle has been working for iXblue on a joint academic-industrial project that aims to develop cold-atom technology for mobile inertial sensing applications. He is currently developing a three- axis hybrid quantum-classical accelerometer for inertial navigation, and a field-deployable all-fibered laser system at 780 nm. Brynle is the author of two industrial patents pertaining to quantum inertial sensors and 30 peer-reviewed publications in the field of atomic, molecular and optical physics.

of Physics Students Vice President, she received the Joel Matthew Orloff Award for outstanding service to the physics department, Institute, or community. Sara also received a National Science Foundation Graduate Research Fellowship. Before starting graduate school, she attended a Critical Language Scholarship program with the United States Department of State to study Chinese in Beijing, and then spend a year at the Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences, as a visiting researcher.

Sara then joined Jun Ye’s group at JILA, University of Colorado, Boulder and National Institute of Standards and Technology. For her PhD thesis which she received from the University of Colorado, Boulder in 2017, Sara and the rest of the strontium team designed and built a new apparatus to make a next-generation clock based on a degenerate Fermi gas in a three- dimensional optical lattice.

Hooked on metrology, but wishing to measure something with more immediate applications, Sara is pursuing her postdoctoral research in cryogenic electron microscopy. Working with a collaboration with professors Holger Müller, Robert Glaeser and Eva Nogales, Sara and the rest of the team have demonstrated the first phase plate for electron microscopy that has a stable phase shift, based on the ponderomotive force from a continuous-wave laser.

In 2011 she then started a PhD at the SYRTE laboratory, in the Inertial Sensor team under the supervision of F. Pereira dos Santos. She worked on a metrological experiment aiming at measuring short-range interactions between an atom and a massive surface. The measurement is realized thanks to atom interferometers using atoms trapped in a 1D vertical optical lattice. The energy levels of atoms in such a trap being shifted from one lattice site to another by the force one aims at measuring.
