IEEE Day celebration in Switzerland on Quantum Computing (Hybrid-Format)


Dear IEEE Members,

We have the pleasure to Invite you to join us in celebrating IEEE Day on the 5th of October 2021.

The topic of Quantum computing is a future direction of IEEE, and today the initiative have collected quite decent amount of scientific material and publications. Fits well with the motto of the day : While the world benefits from what’s newIEEE focuses on what’s next. The Paul Scherrer Institute has been recently announcing the creation of a Quantum Hub, for experimental quantum computer in the canton of Aargau.

Join us in celebrating IEEE members! Worldwide celebrations demonstrate the ways thousands of IEEE members in local communities join together to collaborate on ideas that leverage technology for a better tomorrow. 

The event will be host in an hybrid format.

It will be possible to accommodate up to 50 participants having a Covid certificate and protective mask. Others are warmly welcome to join us on Zoom to follow the presentations.

Please let us know if you intend to join online or onsite.

The program is as follow :

14:00 – 14:10 : Welcome notes by IEEE Switzerland section

Quantum for complex molecular systems

The calculation of molecular properties is a challenging task. Indeed, the required classical
computational resources grow exponentially with the molecular system size. This unfavorable
scaling constrains accurate simulations to small and simple molecules.
In view of the difficulties encountered with the traditional computational paradigm, quantum
computing appears as a natural efficient alternative.

This talk will provide an overview of how quantum processors can be leveraged to solve
problems in quantum chemistry, such as electronic and vibrational structure problems and
molecular quantum dynamics. In particular, I will compare the scaling and the performance of
algorithms designed for fault-tolerant quantum computers with near-term methods for the
state-of-the-art quantum hardware.


Pauline Ollitrault is a Quantum Application researcher at IBM Quantum, IBM Research Zurich, focusing on the design of quantum algorithms for solving problems in quantum chemistry.
Pauline holds a B.Sc. in Chemistry and Chemical Engineering and a M.Sc. in Molecular and Biological Chemistry from the Swiss Federal Institute of Technology in Lausanne (EPFL). She wrote her Master's thesis on "Compressed virtual orbital basis for dispersion interactions" while at UC Berkeley under Prof. Martin Head-Gordon.
She then conducted her PhD thesis "Solving quantum chemistry problems on first generation quantum computers" at IBM Research Zurich and ETH Zurich under Dr. Ivano Tavernelli and Prof. Markus Reiher.

Nanowires for Quantum Computation: From phonon engineering to material design for efficient spin qubits

Nanowires (NWs) are filamentary crystals with diameters in the range of few to several tens of
nanometers, while their length can extend up to tens of micrometers. They are versatile templates for
heterostructures, which can be obtained either axially or coaxially with respect to the nanowire growth
axis. A further advantage of using nanowires as templates for axial heterostructures is that lattice
mismatched materials can be combined as NWs release strain in their radial direction. These unique
properties, together with their nanoscale dimensions, make nanowires promising for several
technological applications. We will discuss their exploitation for quantum computing, both as material
system for hosting spin qubits as well as for phononic computation.
On the one hand, Ge-Si core-shell NWs could be used as platforms to host fast and fully electrical
controlled qubits. 1 Namely, Ge-Si core-shell NWs exhibit a strong hole confinement and a large direct
Rashba spin-orbit coupling (by adding an electric field). [1] For this, nanowires of high quality and
controlled axial directions are needed. We show a way to directly influence the direction of nanowires
grown by the vapour-liquid-solid method by changing the surface density of the nanoparticles deposited
on the substrate.
On the other hand, NWs are also powerful building-blocks for phononic applications. The
manipulation of phonons is a challenging objective, which holds the promise of a step forward in the
exploitation of quantum physics and implies the manipulation of sound and heat. [2] The recently growing
research field called “Nanophononics” deals with the investigation and control of vibrations in solids at
the nanoscale. [3,4] As an example, logical operations using phonons to switch, amplify and route signals
can be realized by nanoscaling. We discuss nanowires (NWs) as powerful building-blocks for phononic

Ilaria Zardo received her diploma in Physics from the Università degli Studi di Roma "Sapienza" in 2007. In 2010, she received her Ph.D. in Physics from the Technische Universität München and Università di Roma "Sapienza" with summa cum laude. Her doctoral thesis was awarded as the "Best Ph.D. Defence" at the Università di Roma "Sapienza". From 2010 to 2011, she was a postdoc in the group of Gerhard Abstreiter at Technische Universität München and from 2012 to 2015 in the group of Erik Bakkers at the Technical University of Eindhoven. In 2014, she successfully applied with the project "NEW: Nanostructures for Energetic Wisdom" for the Innovational Research Incentives Scheme Veni, which is a prestigious Talent Scheme of the Netherlands Organisation for Scientific Research (NWO), meant for talented, creative researchers who are starting their own line of research. She received in 2015 the Hertha-Sponer Prize, awarded to a female scientist for outstanding scientific work in the field of physics. She was appointed as a tenure track assistant professor at the Department of Physics at the University of Basel in 2015 and became a tenured Associate Professor in 2020.
