Eurekalert.org has posted an accessible to a wider public piece about a collaborative work between two QISS nodes, Quantum Group of Oxford (Jonathan Barrett) and Free University of Brussels (Ognyan Oreshkov), read by following this link. The paper concerned is titled Cyclic Quantum Causal Models and is published at Nature Communications. Technical abstract of the paper: …
Several members of the QISS collaboration will be participating to the Vienna Quantum Foundations Conference 2021, hosted by the University of Vienna and the Institute for Quantum Optics and Quantum Information. Talks will be streamed online and recorded. For more information see https://vqf.iqoqi.oeaw.ac.at
The 2021 seminars will start again in September. We are currently inviting speakers and will begin announcing seminars shortly.
Markus Aspelmeyer, Director of the Institute for Quantum Optics and Quantum Information, has joined QISS. The addition of Markus and his group will support the focus point of exploring experimental possibilities to probe the weak field/low energy aka “table-top” regime of gravitational quantum physics. For an interesting popularised take on recent experimental trends see the recent …
We are happy to announce the QISS conference at Western University Ontario for June 6-11 2022, and the previously postponed due to the pandemic QISS workshop at Lesbos, Greece for August 27-31 2022. Further information will appear in the pages listed below. [email protected], June 6-11 2022 [email protected], August 27-31 2022
Constructor theory is a relatively nascent idea in fundamental physics that proposes to underlie all other currently known theories, not to mention those yet to be known, and to solve problems across a host of fields in science and beyond. Logan Chipkin joins Oxford physicist and constructor theorist Chiara Marletto to discuss what constructor theory is, …
Carlo Rovelli has published his new popularised science book, which opens with a scene discussing physics with other QISS members at Lamma Island, during our day off at the [email protected] launching conference of the QISS project. penguin.co.uk/books/…/helgoland
A clock on the ground floor runs slower than a clock on the top floor; this is one of the effects of spacetime curvature caused by our planet’s mass. The effect is minuscule by human standards, but it is a real effect with measurable implications for satellite technology. In [2], it was pointed out that …
By Giulio Chiribella and Zixuan Liu. Pre-publication link. At the microscopic level, the fundamental laws of physics are time symmetric: every fundamental process admits a time-reversal, which describes the same physics seen from the point of view of an observer with an inverted arrow of time. In stark contrast, our everyday experience and our laboratory practice …
When we think operationally about space and time, we usually assume that the objects we use as reference frames are classical systems – like a macroscopic heavy ruler or a clock with sharply defined hands. Quantum reference frames have recently been introduced as a formalism to describe physics when rulers and clocks are assumed to …
QISS is a cross–disciplinary fundamental research initiative in the broader fields of Quantum Information and Quantum Gravity.
