We’re ready to combine optical tweezers with an optical cavity, to do some serious cooling of levitated nanoparticles, good work James S!

We’ve custom-built some miniature ion traps for our electromechanics project. Have fun Yugang!

An accessible review written by James & Ben Stickler has been published in Contemporary Physics. We consider what exactly you can learn by doing quantum experiments with big things, and outline how to do it. Quantum experiments with microscale particlesMillen … Continue reading →

This group has a focus on testing quantum physics using particles levitated in optical fields. Why do we use light? Well, because that was the only field on the block! Now we propose to use electrical fields and qubits to … Continue reading →

Was happy to write a viewpoint with Brian D’Urso on amazing work from Copenhagen; greatly different degrees-of-freedom have been entangled, the spin of atoms and the mechanical motion of a micro-object.

Our short review on gravimetry with quantum nanoparticles has been published in Advanced Optical Technologies. Great to finally work with Dr. Lia Li again and for the first time with Markus Rademacher.

We were featured in this beautiful piece by science journalist and dancer Anna Demming in collaboration with artist Laurene Pilastre. It premiered at Redfest in Bristol.

  Excited to announce that we have received Proof of Concept funding to develop levitated technologies. More information here.

We have had project “Doing More with Less” funded, which will explore the use of optical Orbital Angular Momentum for the control of levitated nanoparticles.  

Here is a video interview of James by UCL Quantum, talking about both general and specific research:
