A Spin-Based Pathway to Testing the Quantum Nature of Gravity
Sougato Bose, Anupam Mazumdar, Roger Penrose +52
A key open problem in physics is the correct way to combine gravity (described by general relativity) with everything else (described by quantum mechanics). This problem suggests t…
Three-Dimensional and Selective Displacement Sensing of a Levitated Nanoparticle via Spatial Mode Decomposition
Thomas Dinter, Reece Roberts, Thomas Volz +2
We propose and experimentally demonstrate a novel detection method that significantly improves the precision of real-time measurement of the three-dimensional displacement of a lev…
Inert shell coating for enhanced laser refrigeration of nanoparticles: application in levitated optomechanics
Cyril Laplane, Peng Ren, Reece P. Roberts +2
We report on a study exploring the design of nanoparticles that can enhance their laser refrigeration efficiency for applications in levitated optomechanics. In particular, we deve…
Roadmap for Optical Tweezers
Giovanni Volpe, Onofrio M. Maragò, Halina Rubinzstein-Dunlop +80
Optical tweezers are tools made of light that enable contactless pushing, trapping, and manipulation of objects ranging from atoms to space light sails. Since the pioneering work b…
Multi-mode and long-lived quantum correlations between photons and spins in a crystal
Cyril Laplane, Pierre Jobez, Jean Etesse +2
The realization of quantum networks and quantum repeaters remains an outstanding challenge in quantum communication. These rely on entanglement of remote matter systems, which in t…
Spectral hole lifetimes and spin population relaxation dynamics in neodymium-doped yttrium orthosilicate
Emmanuel Zambrini Cruzeiro, Alexey Tiranov, Imam Usmani +6
We present a detailed study of the lifetime of optical spectral holes due to population storage in Zeeman sublevels of Nd:YSiO. The lifetime is measured as a functio…
High precision measurement of the Dzyaloshinsky-Moriya interaction between two rare-earth ions in a solid
Cyril Laplane, Emmanuel Zambrini Cruzeiro, Florian Fröwis +2
We report on a direct measurement of the pair-wise anti-symmetric exchange interaction, known as the Dzyaloshinsky-Moriya interaction (DMI), in a Nd3+-doped YVO4 crystal. To this e…
Towards highly multimode optical quantum memory for quantum repeaters
Pierre Jobez, Nuala Timoney, Cyril Laplane +5
Long-distance quantum communication through optical fibers is currently limited to a few hundreds of kilometres due to fiber losses. Quantum repeaters could extend this limit to co…
Multiplexed on-demand storage of polarization qubits in a crystal
Cyril Laplane, Pierre Jobez, Jean Etesse +3
A long-lived and multimode quantum memory is a key component needed for the development of quantum communication. Here we present temporally multiplexed storage of 5 photonic polar…
Coherent spin control at the quantum level in an ensemble-based optical memory
Pierre Jobez, Cyril Laplane, Nuala Timoney +4
Long-lived quantum memories are essential components of a long-standing goal of remote distribution of entanglement in quantum networks. These can be realized by storing the quantu…
Cavity-enhanced storage in an optical spin-wave memory
Pierre Jobez, Imam Usmani, Nuala Timoney +3
We report on the experimental demonstration of an optical spin-wave memory, based on the atomic frequency comb (AFC) scheme, where the storage efficiency is strongly enhanced by an…
