Outreach Training Day

Image
New students means new opportunities to get out of the lab and teaching the public about the weird world of quantum technology. But first, we need to show everyone what demos we have available. This afternoon, we invited the whole group to see what our engagement cupboard has to offer.


Seasoned veterans through to those new to public engagement joined us to get hands on with our demos. Everything from hand held busking demos to more technical demos was on offer to have a play with. Everyone pitched in to find out what is on offer.



Quantum Comic Strips (Quantum PhoComics): The New QET Labs Engagement Project

Image
QET Labs recently added new activities to their highly developed public engagement culture. Among them is Quantum In Conversation, part of the QET Lab’s award wining engagement initiative, Quantum in The Crowd (http://www.bristol.ac.uk/news/2017/october/engagement-awards-2017.html). Quantum In Conversation now reaches out to the children and young people of all educational backgrounds to engage with quantum research in the visual/narrative forms through the ‘Quantum PhoComics’ project.

The project stemmed from the on-going collaboration between QET Labs and their Research Engagement Supervisor, artist and historian Dr Milica Prokic. In November Milica teamed up with QET PhD researchers, Henry Semenenko and Alex Moylett, to deliver a quantum inspired comic strips workshops to young Bristolians.

The first workshop in the series, hosted by the Knowle West Media Centre, included presentations and demos by the researchers, followed by an art session where the initial sketches and storylin…

Royal Society Summer Science Exhibition

Image
The Royal Society Summer Science Exhibition is one of the largest events in the outreach calendar and is attended by thousands. Scientists from all over the UK are invited to display their cutting-edge research during the week-long event. After a competitive application process, the Centre for Quantum Photonics was invited to explain the weird and wonderful world of quantum computing, as one of only 22 exhibits.

Our exhibit took the public on journey to discover how we control light, why we want to use it to create more powerful computers and how the strange world of quantum mechanics will get us there. The first part of the display illustrated how our technology relies on the same physical processes as superfast broadband, confining light using total internal reflection.

We then demonstrated how quantum mechanics can explore problems in unfamiliar ways. By using a Galton box, we showed how quantum particles will take different routes to those we'd normally expect. By using these …

QET Labs at Cheltenham Science Festival 2017

Image
Cheltenham Science Festival is one of the UKs largest public engagement science exhibitions, which has had attendance of 45,000 visitors at previous events. This year’s festival saw researchers from QETLabs showcasing a variety of demonstrations.



QET Labs students and researchers Henry Semenenko and Alasdair Price organised demonstrations ranging from explaining the fundamental properties of light such as polarisation, and how we use it in sunglasses and 3D cinema glasses, to addressing current affairs of hacking encrypted messages and securing communications against malicious adversaries.



The exhibit was well received, engaged with a large number of people and was popular with schools, children and adults from all types of non-technical backgrounds. Many were interested in how optics and quantum technologies work and how it will impact their lives in the near future.

Outreach events are fundamental to inspiring the next generation of scientists, and communicating to a general audien…

QET Labs at Bristol's Festival of Nature 2017

Students from the Quantum Engineering CDT taught the public about light and colour at Bristol’s Festival of Nature this weekend.

The CDT’s 3rd cohort, led by Cohort 1 student Euan Allen (pictured above), attended the event on Saturday and Sunday to demonstrate the effects of microstructures on colour in nature using butterfly wings, beetle shells, and several other naturally iridescent substances.

The event, which attracts thousands to Bristol harbourside annually, aims to educate the public about nature, conservation, and the environment.

Day 3 of the Bristol Quantum Information Technologies (BQIT) workshop

Image
BQIT:17's third and final day saw the workshop draw to a close with another sunny day of talks on detectors, hybrid platforms and integrated photonics.

Kicking things off was Sae Woo Nam from NIST. Sae Woo explained two projects around the subject of superconducting nanowire single photon detectors (SNSPDs): one which showed a detection efficiency when used in practice of over 93%, and another on SNSPDs integrated into waveguides. He finished talking about some work with Dave Wineland integrating these detectors with ion traps. University of Münster's Wolfram Pernice followed this by speaking about developing SNSPDs which are capable of detecting single photons in plane, making them suitable for waveguides.

The first solid state & hybrid systems session began with Almut Beige from the University of Leeds, who explained how we can better understand how to couple optical cavities from working out the Hamiltonian of a beam splitter. She was followed by the University of Bris…

Day 2 of the Bristol Quantum Information Technologies (BQIT) workshop

Image
Day 2 of QET Labs' fourth annual Bristol Quantum Information Technologies (BQIT) saw another sunny day of talks related to quantum technologies.

The quantum information theory stream kicked off with the University of Bristol's Ashley Montanaro, detailing two recent algorithms to provide quadratic speedups for backtracking and Monte Carlo methods. This was followed by Ulm University's Martin Plenio, who talked about efficient ways of performing quantum state tomography, resulting in being able to experimentally demonstrate efficient state tomography for 20 trapped ions. Laura Mancinska, also of the University of Bristol, concluded this topic with a talk on how to verify that a state you are given is entangled.

A coffee break precluded Winfried Hensinger of the University of Sussex, who began the scaling up theme by explaining the background of ion trap quantum computing, before introducing his blueprint for constructing a large-scale quantum computer. This was followed by …
