Meeting ID: 923 7994 3630
Passcode: 577482
Abstract: There are dozens of efforts, in academia, industry, and national labs, dedicated to building error-corrected quantum computers. Achieving this milestone will require understanding and controlling complex quantum noise, including non-Markovian noise. Such noise spans many qubits and many gates, leading to highly complex spatial-temporal quantum-correlated structures. Both describing and characterising such noise have been outstanding challenges, hindering the hopes of controlling this noise.
I will present recent theoretical breakthroughs to express all quantum non-Markovian phenomena in terms of a multi-time density matrix. In this picture, quantum processes possess complex temporal entanglement responsible for exotic dynamical phases, quantum chaos, computationally complex processes, and much more. The culmination of these effects leads to a new discipline that we call many-time physics in analogy to many-body physics.
An immediate application of many-time physics is a set of operational tools to characterise and control complex noise. In particular, I will report both the detailed features and coarse structures of noise in real quantum devices, including temporal entanglement. We then go on to tame this noise with high efficacy using active control, along with the characterisation information.
Biography: Since mid-2022, Kavan Modi has served as the founding Director of the Centre for Quantum Technology at Transport for New South Wales. Currently, he is on leave from Monash University, where he has been a member of the faculty at the School of Physics and Astronomy since 2014. Prior to this, he was a postdoctoral fellow at the Clarendon Lab, University of Oxford (2012-2013) and at the Centre for Quantum Technology, National University of Singapore (2009-2011). He received his Ph.D. under Prof. George Sudarshan at the University of Texas at Austin in 2008. His research, at Monash, focuses on understanding the structure of complex quantum processes so that they can be characterised and controlled in quantum computers. His research, at TfNSW, focuses on developing quantum algorithms to aid transport use cases. On the whole, his research builds meaningful bridges between fundamental physics and its applications in engineering and software development.
