I am a researcher designing silicon chips to connect and control single spins currently based at the University of Bristol.

@BristolCouncil No it isn’t. It’s been closed for a disgraceful amount of time (over three years) in Lockleaze https://t.co/OmAsZIgdYX

Photon was a fantastic conference as always! Well done Chair @DrAlexClark

[Alex Clark @DrAlexClark]

@QETLabsBristol crew at #Photon2024 in Swansea last week! Awesome meeting with great talks and posters in a nice setting. Looking forward to Photon 2026 in Newcastle! @qqq_iop @IOPOpticalGroup

[Joe Smith @joesmio]

Nice invited talk from Prof Krishna Balram to kick off Photon 2024 in sunny Swansea! @QETLabsBristol

[Joe Smith @joesmio]

Very privileged to present our work and connect with many brilliant diamond colour centre scientists at NDNC Sydney 2024.

@darrenpjones You're normally spot on but the political stunt here has reaffirmed my vote for @HeatherMack4 /Greens in Lockleaze tomorrow.

[Joe Smith @joesmio]

Well done to @hcwengbilly for the hard experimental work realising this idea @QETLabsBristol

[Joe Smith @joesmio]

If we're going to exploit the atom-like nature of solid state defects, we need to be able to address them at scale in small volumes (micron-spacing). Spins typically need lots of microwave power, which means crosstalk from one control signal would affect neighbouring spins.

[Joe Smith @joesmio]

The dual-loop microelectronics presented here is compatible with photonics (both waveguides into the loop gap and bullseye-type structures in its centre) and is hopefully useful for all types of optically-active spins.

@AndreiVraji @NYUPhysics Very many congratulations mate!

[Joe Smith @joesmio]

Check out this video explaining our recent work on robotics for quantum technology!

[University of Bristol @BristolUni]

Scientists carrying out quantum research will be able to do so faster and more adaptably, thanks to a new robotic arm which could hold the key to major breakthroughs 🧠

Great times in the lab! Hao-Cheng’s first Rabi oscillation and Vivek’s first cryogenic PL #quantum @QETLabsBristol

@Conservatives @michelledonelan This is really ill-judged and sad. Shame on you for politicising science Donelan.

[Joe Smith @joesmio]

Really enjoyed this workshop. Stimulating discussions on Materials for Quantum, the national quantum strategy, UK fab facilities, startups, career development. A great network to be part of!

[Materials for Quantum Network @mat4quantum]

And that's a wrap! 🙌

Thank you to everyone who joined us at the #M4QN Early Career Researcher Meeting 2023!

Held at Sedgebrook Hall, the event featured talks by industry and academic leaders, workshops, and networking opportunities

Lovely to be back with friends old and new last week, to celebrate ten years of the Quantum Engineering CDT

[Quantum-Engineering @BristolQE]

Celebrating our @BristolQE 10th annual Cross cohort conference in Vale Resort, Wales. Students interact and learn about science outside of their own research field. Joined by previous staff and alumni from Industry and academia for this special event!

[Joe Smith @joesmio]

Excellent talk by @hcwengbilly presenting our work on foundry integrated NV centre photonics #CLEOEurope @QETLabsBristol

[Joe Smith @joesmio]

Great to be seeing old friends and presenting new work at #EMRS in Strasbourg. I am holding a 33 mm diameter single crystal diamond!

[Joe Smith @joesmio]

After some trepidation, we let the robot loose on our confocal microscope, to find out the orientation of an NV centre spin! It works in this vibration-critical environment and is accurate to 1-deg accuracy, 0.1 mT error.

[Joe Smith @joesmio]

Quantum experiments are challenging. For me one of the difficult things has been to align vector fields when complicated optics and stages get in the way. We had an idea, use a robot!

[Joe Smith @joesmio]

One cool thing: a magnetic field vector can be generated from several points in space (non-invertible). If something like a lens or the stage is in the way, we give an algorithm to move the robot to a safe location and produce the same magnetic field.
