Seminar by Maciej Lewenstein

We are happy to announce that Prof. Maciej Lewenstein from ICFO is going to visit us and deliver a seminar.

Speaker: Maciej Lewenstein (ICFO – Barcelona)
When: Tuesday, 26th April 2022, 2:30PM (CEST)
Where: Aula Polvani & online (Zoom)

Title: Quantum Information Science and Quantum Technologies at Quantum Optics Group at ICFO

In my talk I will give an overview of research lines in my group that belong to the Quantum Information area: 1) Detection and characterization of entanglement and Bell correlations in many body systems; 2) Quantum Simulators; 3) Quantum Thermodynamics; 4) Quantum Metrology and Estimation; 5) Interpreting Quantum Phenomena in Music. I focus on demand on those aspect that will be the most interesting for the audience.

New Visiting Scholar and Seminar

Heng-Ji Li from the School of Computer Science of the Beijing University of Posts and Telecommunications is going to join our group as a visiting scholar starting from April 2021.
Welcome on board Heng-Ji!

He is going to deliver our group seminar. See the details here below.

Speaker: Heng-Ji Li (Beijing University of Posts and Telecommunications, CHN)
When: Wednesday, 7thh Aprile 2021, 3PM (CET time)
Where: online (Zoom)

Title: Accomplishing quantum information tasks with coined quantum walks

Quantum walks (QWs) have received much attention due to their many potential applications for quantum information processing in recent years. In our work, we take advantage of the properties of coined quantum walks to accomplish some quantum information tasks, such as quantum teleportation, quantum information splitting and quantum teleportation of shared quantum secret. To do it, different kinds of models of QWs are used, such as QWs with multiple walkers, coins and so on. This work opened wider application of QWs and provided inspiration to explore the potential applications of QWs.

Seminar by Nathan Shammah

We are happy to announce our next seminars.

Speaker: Nathan Shammah (Unitary Fund)
When: Thursday, 26th November 2020, 3pm (CET)
Where: online (Zoom) 

Title: Quantum error mitigation on noisy quantum computers
Error-mitigation techniques improve computational performance (with respect to noise) using minimal overhead in quantum resources by relying on a mixture of quantum sampling and classical post-processing techniques. In this talk I will provide a brief overview of error mitigation techniques and a hands-on introduction to an open-source package for error-mitigation in quantum computation, Mitiq [1,2], which implements zero-noise extrapolation and soon probabilistic error cancellation [3].
