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 test the limits of quantum mechanics. Find a longer synopsis here.
Quantum electromechanics with levitated nanoparticles
Lukas Martinetz, Klaus Hornberger, James Millen, M. S. Kim & Benjamin A. Sticklernpj Quantum Information 6, 101 (2020)
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:
As academia in the UK prepared to go on strike, we took at different approach in the group. Moving from microspheres to macrospheres, a great evening for our growing group!
We will have a new project entering the Quantum Workshop! KCL’s Arts 7 Intelligence programme has funded the creation of a mobile electrical trap, to explore our visual understanding of data, in collaboration with artist Steven Claydon. Watch this space….
Our review article Optomechanics with Levitated Particles has been published in Reports on Progress in Physics!
