UPDATED – VIDEO of Suzanne’s talk
Building large-scale quantum computers: Fundamentals, technology and applications
Abstract: This seminar will explain the fundamental concepts of the Quantum Computer (QC) and how these systems might be able to perform certain tasks that classical computers find incredibly difficult. The different models of quantum computing will be introduced and the advantages and disadvantages of each described. A promising model known as Adiabatic Quantum Computing (AQC) will be discussed, an approach which can be applied to some very interesting problems in a wide variety of fields: Biology, microprocessor design, pharmaceuticals, economics, transport, chemistry and business. The talk will also examine some case studies of industrial applications in these fields where QC may be extremely useful.
There will be a review of some of the experimental challenges involved in building QCs, and a focus on a particularly promising version known as the ‘superconducting flux qubit processor’. The devices involved in this type of QC are fabricated using a process similar to semiconductor technology, but using Niobium and Aluminum rather than Silicon as the device materials. There will be a brief overview of the physics which causes these devices to demonstrate ‘macroscopic quantum coherence’- an effect which allows us to scale up quantum effects to a size where we can manipulate them easily, and why the devices must be cooled to millikelvin temperatures for them to work properly.
The power of quantum computing is often skewed by the media, with quantum computers being hailed as ‘futuristic’ replacements for desktop machines, whereas the reality is that they are very specialized machines, and therefore more like fast co-processors. The talk will therefore also describe the limitations of quantum computers, both in theory and in terms of what can be practically built.
About the speaker: Dr Suzanne Gildert is currently working as an Experimental Physicist at D-Wave Systems, Inc. She is involved in the design and testing of large scale superconducting processors for Quantum Computing Applications. Suzanne obtained her PhD and MSci degree from The University of Birmingham UK, focusing on the areas of experimental quantum device physics and superconductivity.
Teleplace is one of the best 3D applications for telework, online meetings, group collaboration, and e-learning in a virtual 3D environment (v-learning). Those who already have Teleplace accounts for teleXLR8 can just ahow up at the talk. There are a limited number of seats available for others, please contact Giulio Prisco if you wish to attend.
