Quantum Computing Theory in Practice

The past two years have seen rapid advances in building increasingly large-scale quantum computers. It is now widely expected that there will be a demonstration, within the coming months, of a device that cannot be simulated by any classical computer (so called ‘quantum computational supremacy’). The prospect of a relatively near-term device capable of a quantum advantage has sparked a huge amount of excitement both in academia and in industry. The conference will cover the central questions in this emerging field, focusing on how to use quantum computers to solve some of the grand challenges of our time, such as drug discovery or the development of energy-efficient industrial processes or new catalysts.

Topics will include quantum simulation, computational quantum chemistry and quantum algorithms for solving optimization problems. We will also invite speakers to talk about practical aspects of quantum programming and running experiments on current and imminent quantum computing hardware. The final theme will look to the future, with talks on scaling up quantum computers and new quantum algorithms.

The conference will include invited and contributed talks, together with a session bringing together end-users with quantum computing experts, and a poster session.

The registration deadline has passed.

Conference participants may also be interested in the Bristol Quantum Information Technologies Workshop, to be held in Bristol the previous week (1-3 April).

Call for submissions (deadline 11 January 2019)

Submissions are invited for contributed talks. Talks will be selected on the basis of scientific excellence; fit to the topic of the workshop; and balance of the programme.

Submissions should correspond to recent research contributions to quantum information and computation. The workshop will not publish proceedings, and work which has been, or will be, published elsewhere is welcome. Areas of interest include, but are not limited to:

  • Applications of quantum computers
  • Architectures for quantum computing
  • Quantum algorithms
  • Quantum compilation and circuit optimisation
  • Quantum error-correction and fault-tolerance
  • Simulation of quantum systems
  • Theory of near-term quantum computing
  • Verification of quantum devices

All submissions for talks must be made electronically through the online submission system EasyChair at https://easychair.org/conferences/?conf=qctip2019

A submission should consist of a full paper corresponding to the work, including technical details. This manuscript may be from an on-line repository, such as the arXiv; however, a PDF copy of it must be uploaded. If your submission consists of multiple papers they should be merged into a single file.

We encourage all workshop attendees to present a poster. Poster details can be provided during registration.

Conflict of interest: Programme Committee members must declare a conflict of interest on submissions where this is relevant (such as ones where they, or a close associate, are a coauthor) so that they are not involved in the discussion of these papers.

Colloquium – Professor Tiina Roose, University of Southampton

Title: Multiscale image-based modelling in biology

In this talk I will describe a state of the art image based modelling in several seemingly different areas of biology. I show examples from biomedical (lymphatic, vascular and lung system) and agricultural problems of plant soil interaction. I will describe the workflow from imaging (X-ray CT, XRF, SEM-EDX, histology), image reconstruction, image segmentation, computation and how to utilize this work stream to synthesise new scientific knowledge. In particular I will also outline several challenges and bottlenecks in this process to hopefully encourage more mathematicians to get involved in the full pipeline.


Further information

The talk will be held in Tyndall Lecture Theatre, from 4pm – 5pm and will be followed by a drinks reception in the Maths common room.

The event is open to University of Bristol staff and students.

Colloquium – Professor Bernd Sturmfels, University of California, Berkeley

Title: Varieties of signature tensors

We discuss recent developments in computational algebraic geometry that were motivated by the study of rough paths in stochastic analysis. Every path in a real vector space is encoded in a signature tensor whose entries are iterated integrals. As the path varies over a nice family we obtain an algebraic variety with interesting properties.

Further information

The talk will be held in Mott Lecture Theatre (G12), Physics, from 5pm – 6pm and will be followed by a drinks reception in the Maths common room.

The event is open to University of Bristol staff and students.

Colloquium – Dr Miranda Mowbray, University of Bristol

Title: Predictive analytics: you can’t have it all

I will talk about limits to predictive analytics. The main application I’ll talk about is recidivism prediction – predicting whether a convicted criminal is likely to reoffend. However what I will say applies to predictive analytics more generally. As Alexandra Choldecova pointed out in the wake of a controversy about the COMPAS recidivism prediction algorithm, except in trivial cases, it is not mathematically possible to maximize the accuracy of recidivism prediction while meeting some fairness requirements for groups with different underlying recidivism rates. It is a policy choice whether or not to accept reduced accuracy, at least in the short term, in return for meeting fairness conditions. I will discuss this and some other limits to prediction that require policy choices. To make these choices, we need informed discussion and collaboration between techies, lawyers and policy makers. Just for fun, my slides will include 79 cats, a catbot, and Catwoman.

Further information

The talk will be held in Enderby Lecture Theatre (B16/B17), Physics, from 5pm – 6pm and will be followed by a drinks reception in the Maths common room.

The talk is open to all University of Bristol staff and students as well as the general public. We ask that all attendees please register in advance of the event.

Colloquium – Professor Yang Wang PhD, Hong Kong University of Science and Technology

Title: Can Mathematics Solve Mysteries in Literature?

There have been no shortages of controversies in literature, from old questions such as whether Cao Xueqin wrote all 120 chapters of “Dreams of Red Chamber”, widely known as the greatest work of Chinese literature, to new questions such as whether Obama actually wrote his autobiography “Dreams From My Father”.

For mathematicians, it is interesting to ask whether mathematics can be used to settle these controversies. In this talk, I will give an overview on how mathematics can be applied to analyze the “style” of an author and the related field of study called “stylometry”. I will show that mathematics can be used to almost definitively settle many such controversies.

Further information

The talk will be held in Mott Lecture Theatre (G12), Physics, from 3.30pm – 4.30pm and will be followed by a drinks reception in the Maths common room.

Women in Mathematics: Opportunities for the Future 2018

Enjoying your degree in mathematics? Interested in discovering where further study in maths can take you?

Join us for our annual Women in Mathematics event, 6th – 7th November 2018 – open to female and non-binary students in the UK and Ireland.

A PhD in mathematics can offer you independence, challenging problems and an inspiring job, as well as the chance to travel and the opportunity to make a difference.

This two-day event is aimed at encouraging female mathematics students, including those who self-define as women or whose gender identity includes “woman” or is non-binary, to consider continuing their studies to PhD level.

The event features talks from mathematicians working both in universities and industry, giving insight into their current roles and their careers to date. Even more importantly, there is ample time to talk in small groups to the other participants who are facing the same decisions, and to current PhD students who have recently faced the same questions.

Please note that the Wednesday afternoon session is open to all students.

The full programme and details on how to apply can be found below.
