Probabilistic laws on groups

Guy Blachar
(Weizmann Institute)
Abstract

Suppose a finite group satisfies the following property: If you take two random elements, then with probability bigger than 5/8 they commute. Then this group is commutative. 

Starting from this well-known result, it is natural to ask: Do similar results hold for other laws (p-groups, nilpotent groups...)? Are there analogous results for infinite groups? Are there phenomena specific to the infinite setup? 

We will survey known and new results in this area. New results are joint with Gideon Amir, Maria Gerasimova and Gady Kozma.

Talk (even more) about your PhD

OxWEST (Oxford Women in Engineering, Science and Technology) is running a 'what actually is a PhD' evening and we need your help. We're looking for PhD students to come and speak to undergraduates about what doing a PhD actually entails and answer any questions they may have to help them answer the dreaded question of 'should I do a PhD?'

Come by to G & D's on St Aldate's on Friday 1st November (week 3) at 8-10pm.

Oxford University’s open access publication policy now includes rights retention

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.

Events around the University

There are always masses of talks, events and exhibitions across the University, so if you haven't ever checked out the University listing:

Randomised Quantum Circuits for Practical Quantum Advantage

Bálint Koczor
(Mathematical Institute (University of Oxford))
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.
