Certified randomness from quantum speed limits
Caroline L. Jones, Albert Aloy, Gerard Higgins +1
Quantum speed limits are usually regarded as fundamental restrictions, constraining the amount of computation that can be achieved within some given time and energy. Complementary…

Optical Interferometric Readout of a Magnetically Levitated Superconducting Microsphere
J. J. Hansen, S. Minniberger, D. Ilk +8
We probe the motion of a 6 magnetically levitated superconducting microsphere using optical interferometry at 3 K, achieving a resolution better than 1 , and u…

A truly relativistic gravity mediated entanglement protocol using superpositions of rotational energies
Gerard Higgins, Andrea Di Biagio, Marios Christodoulou
Experimental proposals for testing quantum gravity-induced entanglement of masses (QGEM) typically involve two interacting masses which are each in a spatial superposition state. H…
