Quantum Computing Theory in Practice Conference
Centre for Mathematical Sciences, Cambridge | 6-8 April 2020

Centre for Mathematical Sciences in Cambridge

Next year’s Quantum Computing Theory in Practice Conference 2020 will take place in Cambridge.

After decades of research, we are finally getting closer to unlocking the power of quantum computing. With recent developments in quantum hardware and software, quantum computations that are of real-world relevance, for example in computational chemistry, seem to be within reach. However, a lot of theoretical groundwork has yet to be done to reach these ambitious goals.

Continuing the previous series of Heilbronn quantum algorithms meetings (2010-2019) hosted in Bristol and Cambridge, QCTIP fosters discussion between theorists and practitioners of quantum computing. With keynote speakers, a series of invited talks from academia and industry, poster sessions and panels, we will take stock of the newest developments in the field and map future developments. Riverlane is proud to be hosting the conference.

The first theme of the conference is the theory of the whole quantum software stack – from quantum algorithms to quantum programming languages to quantum computing architectures. Second, we will discuss practical aspects of running experiments on current and NISQ devices. As a third future-looking theme, we want to touch on roads to scaling up to more and higher quality qubits and the path to bringing down hardware requirements for quantum computations.

Organising Committee: Steve Brierley (Riverlane), Noah Linden (University of Bristol), Ashley Montanaro (University of Bristol), Leonie Mueck (Riverlane)

Public Event - Quantum Computing: The Truths, the Myths, and the Challenges

Separating the reality from the fiction, and exploring the future of quantum computing; how will it be useful and how will we get there?

Quantum computing - what is it? What are the key challenges that scientists face? And how will it affect the future?

Hosted by Lizzie Gibney, Senior Reporter at Nature, this event has a top line up of panellist speakers representing both academia and industry, to answer some of the biggest questions on the subject.

As part of a 3-day Quantum Computing Theory in Practice Conference; this public event aims to spark your curiosities and deliver the real truths of quantum computing, and it's potential to shape the modern world.
