The University of Oxford Open Access Publications Policy, and University Statute XVI which covers intellectual property rights, have now been updated to incorporate rights retention. This re-affirms the University’s preference for the green or self-archiving route to open access.
Rights retention allows authors to retain the rights to their work, rather than signing these over to a publisher. This means authors can share and reuse their work without having to seek the publisher’s permission.
Nicola Pedreschi was a postdoc in Oxford Mathematics until the summer. But like several Oxford Mathematicians he is a musician, in Nicola's case in the band Eveline's Dust. So here is the lead single from their new album. This is their website.

Randomised Quantum Circuits for Practical Quantum Advantage
Abstract
Quantum computers are becoming a reality and current generations of machines are already well beyond the 50-qubit frontier. However, hardware imperfections still overwhelm these devices and it is generally believed the fault-tolerant, error-corrected systems will not be within reach in the near term: a single logical qubit needs to be encoded into potentially thousands of physical qubits which is prohibitive.
Due to limited resources, in the near term, hybrid quantum-classical protocols are the most promising candidates for achieving early quantum advantage but these need to resort to quantum error mitigation techniques. I will explain the basic concepts and introduce hybrid quantum-classical protocols are the most promising candidates for achieving early quantum advantage. These have the potential to solve real-world problems---including optimisation or ground-state search---but they suffer from a large number of circuit repetitions required to extract information from the quantum state. I will detail a range of application areas of randomised quantum circuits, such as quantum algorithms, classical shadows, and quantum error mitigation introducing recent results that help lower the barrier for practical quantum advantage.

Written & co-directed by Marcus du Sautoy - an exploration of free will, war and mathematics.
Eminent mathematician Andre Weil is on a journey from France to India, Finland and beyond, to discover whether we really have free will or if all our choices are predetermined. Imprisoned in Rouen during the Second World War, Weil faces a choice that will determine his fate - but his decision just doesn’t make sense. Is life a mathematical theorem of logical strands? Because sometimes it just doesn’t add up.
