PQI2020 Public Lecture: Scott Aaronson

Dr. Scott J. Aaronson, David J. Bruton Centennial Professor of Computer Science at the University of Texas at Austin, gave the PQI2020 Public Lecture.

Last fall, a team at Google announced the first-ever demonstration of "quantum computational supremacy"---that is, a clear quantum speedup over a classical computer for some task---using a 53-qubit programmable superconducting chip called Sycamore. In addition to engineering, Google's accomplishment built on a decade of research in quantum complexity theory. This talk will discuss questions like: what exactly was the contrived problem that Google solved? How does one verify the outputs using a classical computer? And how confident are we that the problem is classically hard---especially in light of subsequent counterclaims by IBM? He'll end with a proposed application for Google's experiment---namely, the generation of certified random bits, for use (for example) in proof-of-stake cryptocurrencies---that he has been developing and that Google is now working to demonstrate.

13th Elsevier Distinguished Lecture in Mechanics

Quantum Information Science (QIS) and Artificial Intelligence (AI) are having a dominant influence in many aspects of life in industrial societies. The importance of these fields to the global economy and security are very well recognized, promoting the rapid growth of the related technologies in the upcoming decades. This growth is fueled by very large investments by many governments and leading industries. An arena in which QIC and AI are being promoted to play a more significant role is combustion. The fact is that...

POSTPONED Public Lecture: Towards a Large Scale Quantum Computer using Advanced Fabrication Technologies

Speaker(s): 
James Clarke
Dates: 
Thursday, March 26, 2020 - 4:00pm

This event will tentatively take place in Fall 2020.

A large scale quantum computer could change the world.  Performing certain calculations in minutes that would take the largest supercomputer millions of year.  The impact to applications such as cryptography, chemistry, finance, etc would be huge.

Today’s quantum processors are limited to 10’s of entangled quantum bits.   If you believe the hype, a commercially relevant system is just around the corner that can outperform our largest supercomputers.   The reality, however, is that we are still at mile 1 of...

Optica fantastica: images to illuminate the physics of light

Speaker(s): 
Sir Michael Victor Berry
Dates: 
Wednesday, September 26, 2018 - 4:00pm to 5:00pm

A talk based entirely on pictures. Seas sparkle, sunshine generates rainbows, ships make waves. The explanations of these familiar phenomena are as abstract as elsewhere in physics, but pictures are helpful because in light and waves on water we can often see what we are thinking about. There are other optical phenomena that are not immediately perceived (associated with polarization or fine-scale interference, for example), but even with these we can generate pictures to help our understanding. Poets and novelists, as well as painters, have sometimes represented optical phenomena in ways...

Michel Devoret: The Quest for the Robust Quantum Bit

The PQI2016 Public Lecture was given by Prof. Michel Devoret of Yale University. In his talk entitled “The Quest for the Robust Quantum Bit”, Devoret presents the progress of his group towards the conservation of quantum information via the use of “CAT-states”, a wink and a nudge to Schrodinger’s cat in its superposition of alive and dead states.

He describes the outstanding research carried out in his lab and the future considerations of his newly founded company, Quantum Circuits, Inc., which are taking us one step closer to the advent of the ultimate super computer: the quantum computer.
