Welcome Suraj!

We are delighted to welcome our third PhD student Suraj Goel, who joins us from India!

Suraj has completed his B.Tech in Engineering Physics at the Indian Institute of Technology Delhi (IITD), where he has worked on structured light and quantum information. His enthusiasm towards physics and experience in electronics will be valuable to the group.

Welcome to the BBQ Lab, Suraj!

Quantum Journal: Pixel Entanglement

Twas the night before Christmas, when all through the lab,
Not a creature was stirring, not even a browser tab,
The laser was focused on the crystal with care,
In the hope that pixel entanglement soon would be there!

In our recent paper published in the journal Quantum, we demonstrate high-dimensional entanglement of “pixels” of light with a record dimensionality, quality, and measurement speed! We achieved entangled state fidelities of up to 94.4% in a 19-dimensional state-space, entanglement in up to 55 local dimensions, and an entanglement-of-formation of up to 4 ebits. We were also able to improve upon the time taken by previous techniques for measuring entanglement by more than two orders of magnitude! This work was done in collaboration with our friends in Vienna and the Czech Republic.

Winning the Double at Q-Turn2020!

At this year’s Q-Turn some 600+ researchers met online to share their works in quantum science, highlighting top-quality experimental and theoretical work on quantum information technology and foundations. Holding together this meeting is Q-turn’s awareness program, promoting diversity, equity, inclusion, intersectionality, responsible research, workers’ rights, as well as physical and mental health in quantum science and technology. Making Q-turn a vital and amazingly fullfing meeting for the sciences and everybody involved.

To top the incredible week off, BBQLab students Natalia and Vatshal won two prizes(!), the gold poster prize, and silver student presentation prize, respectively.

Congratulations to both of you, and thankyou Q-Turn2020 for an amazing week!

BBQ Lab @ Q-Turn 2020

This week we are attending Q-Turn 2020, an international quantum information workshop series being held virtually this year. I have also had the honour of serving as programme committee chair for this very exciting event!

In addition to showcasing cutting-edge scientific research on all things quantum, Q-Turn 2020 has an awareness programme focussing on a wide range of issues such as mental health and harassment in academia.

Our group will be represented by Vatshal and Natalia, who are presenting a talk and a poster respectively on some of our recent work. We hope to see you there!

Here is a nice video summary of Natalia’s poster:

Vatshal wins 1st Prize….Twice!

Congratulations Vatshal!

Our very own Vatshal Srivastav won the 1st prize in the Heriot-Watt, Engineering and Physical Sciences, Postgraduate Resarch Day for his poster on our upcoming work “Genuine High-Dimensional Quantum Steering”.

That’s not all. He ALSO won 1st prize at the Inaugural Brazil-Scotland Meeting on Structured Light (BraSco)!

Two weeks, two prizes, what’s next for this man…
