Potential visits and meetings are with groups at the Niels Bohr institute, the NovoNordisk foundation quantum initiative, the Nato Quantum Technology Center and more. https://qdev.nbi.ku.dk/ https://nbi.ku.dk/english/research/quantum-optics-and-photonics/ https://novonordiskfonden.dk/en/news/major-investment-for-developing-denmarks-first-fully-functional-quantum-computer/ https://investindk.com/insights/new-danish-nato-center-for-quantum-technology Details about transportation and housing will follow, but we already now ask the WACQT PhD-students to save the dates. *** We consider the trip mandatory for all WACQT PhD students, the reason being that we don?t have too many opportunities to meet. Also, anyone else in WACQT is, given that there is enough space, welcome to join. We?ll open the registration around 1st of December. All the best, The Graduate School Committee / Göran PS You most probably should also save-the-week 21-25th of August for the 3rd WACQT Summer School, most probably at the wonderful south coast of Sweden. We?ll send more information about this soon.

Prof Cabello is an internationally renowned expert in the field. His lectures tomorrow aims at presenting quantum contextuality from the very start, also for for people that may not have heard about it. The lectures will be given 10-11 and 13-14 and can be followed on Zoom https://lu-se.zoom.us/my/stefan.kroll Title: Quantum contextuality: An introduction (I & II) Duration: 45+45 min Speaker: Adán Cabello Abstract: In a nutshell, contextuality (in the Kochen and Specker's sense) is the impossibility of explaining, by means of a single probability distribution, the outcome probability distributions of some sets (called contexts) of jointly measurable observables (such that each observable is in several of these sets).The name contextuality reflects that, if one thinks that measurements reveal preexisting outcomes of the measured system, then this impossibility forces one to conclude that observables? outcomes must depend on the context. However, an arguably simpler explanation is that measurements do not reveal preexisting outcomes. Contextuality encapsulates in a precise way some key differences between quantum and classical physics and helps us to understand the origin of the power of quantum computers. The aim of these two lectures is to help you learn: (i) What is contextuality and how it is detected and quantified. (ii) Where can contextuality occur (according to mathematics) and where does it occur according to quantum mechanics. (iii) What is Bell nonlocality and why Bell nonlocality is a particularly important form of contextuality. (iv) What is an ideal observable and why quantum contextuality for ideal observables provides a unique insight to understand what quantum mechanics is telling us about the world. (v) Some fundamental examples of quantum contextuality, including single-system state-dependent and state-independent contextuality, Hardy-like nonlocality, full nonlocality, quantum violations of bilocality, and correlations that explain the need of complex numbers. (vi) Some applications of quantum contextuality, including device-independent quantum key distribution, fault-tolerant universal quantum computation via magic state distillation, and the quantum computational advantage in shallow circuits.

For you at Chalmers, the location is Fasrummet and it will also be broadcasted on zoom: https://chalmers.zoom.us/my/goran.l.johansson Passcode: Kvant22 Cheers Göran Title: Quantum nonlocality: How does nature do it? (A simple explanation of the limits of correlations in nature) ?Abstract: Nature violates Bell inequalities. However, it is not clear why this violation occurs and what does it mean. There are several possibilities: (i) It could indicate that measurement outcomes are governed by nonlocal hidden variables. (ii) It could indicate that measurement outcomes are governed by local hidden variables and measurements depend on the hidden variables. (iii) It could indicate that neither measurements nor measurement outcomes are governed in any way by hidden variables. Here, I examine these possibilities under the light of some recent developments in the program of deriving from fundamental principles the sets of quantum correlations for Bell and Kochen-Specker contextuality scenarios and show that the option that, at first sight, has less explanatory power is the one that actually explains more.?

The GRP can fund longer or shorter visits, hosted by one of our WACQT project PIs at any of our partner universities. Please make use of this opportunity! WACQT project PIs, nominate visitors to me and/or Linda Brĺnell. Tell who you plan to invite, with title, a short presentation, citizenship, visit period and anything else that is relevant. Approval is usually quick. Junior researchers and collaborators nominate to your PI. More information can be found in the attached document.
