Advanced Quantum Technologies 6, 2200061 (2022) Domenico Ribezzo et al. Around 40 years have passed since the first pioneering works introduced the possibility of using quantum physics to enhance communications safety. Nowadays, quantum key distribution (QKD) exited the physics laboratories to become a mature technology, triggering the attention of States, military forces, banks, and private…

Entropy 24(11), 1642 (2022) Andrea Vinante, Chris Timberlake and Hendrik Ulbricht Magnetically levitated microparticles have been proposed as mechanical sensors with extreme sensitivity. In particular, micromagnets levitated above a superconductor can achieve very low levels of dissipation and thermal noise. In this paper, we review recent initial experiments and discuss the potential for using these…
