Abstract: In Part II of Quantum Shorts Conversations, we welcome theshortlisted and winning filmmakers of the recent Quantum Shorts film festivalfor a conversation about quantum physics, filmmaking, and everything inbetween. This livestream is hosted by shortlisting judge Dr Michael Brooks. Hewill be joined by filmmakers Aurél Gábris and Réka Deák (Quing Solomon -Finalist), Nuno Serrão (We are all on the same bus - Finalist), ChrisWilloughby (Schrödinger Holmes and the Quantum Crimewave - Finalist), and JackDavies (Vacation - Runner Up). Scientists David Hutchinson, Director of theDodd-Walls Centre for Photonic and Quantum Technologies in New Zealand, andSally Shrapnel, Chief Investigator at the ARC Centre of Excellence forEngineered Quantum Systems (EQUS) in Australia are the guest panelists for theevent.

CQT Colloquium by Renato Renner, ETH

Title: Quantum information-theoretic constraints on the accuracy of clocks
Date/Time: 29-Apr, 04:00PM
Venue: Online Event

Abstract: The maximum accuracy of today's best clocks is mostly determined by how well we can isolate them from environmental noise. But does this mean that, if we had perfect technology, we could build infinitely precise clocks? The answer to this question is no --- even perfect devices are subject to constraints on how accurately they can measure time. In my talk I will explain what these constraints are and how they can be understood from a quantum information-theoretic perspective.

CQT Talk - Quantum Machine Learning Journal Club Talk by Oleksandr Kyriienko, University of Exeter, UK

Title: Designing quantum software with Hamiltonian simulation and differentiable quantum circuits
Date/Time: 22-Apr, 07:00PM
Venue: Online Event

Abstract: Quantum computing in the near-term faces a challenge of limited quantum depth due to the relatively high noise level. To use the potential of NISQ devices we need to come up with new software solutions. These can be based on: 1) engineering of a system Hamiltonian and analogue simulation for designing the efficient workflow; 2) variational search of optimal quantum circuits exploiting the power differentiable computing. In the talk, I will first describe the evolution-based protocols for ground state preparation and energy estimation [O. Kyriienko, npj Quantum Information 6, 1 (2020); T. A. Bespalova, O. Kyriienko, arXiv:2009.03351]. Using quantum dynamics as a resource for computation, they are suitable for analogue operation and can help to study strongly correlated material science models. Second, I will discuss advances in the near-term computing with differentiable quantum circuits (DQCs), and present our recent results on DQC-based nonlinear differential equation solver.
