This demonstration extends interaction-free measurement beyond a single item, sequentially probing up to five distinct objects with a solitary photon. The work offers a practical route towards scaling this…...

2+ hour, 37+ min ago  (309+ words) Existing time synchronisation methods face fundamental limits imposed by signal propagation and environmental noise. Quantum clock synchronisation protocols now offer the potential to surpass these classical precision bounds, with improvements in clock stability revealed as exponential with increasing numbers of…...

2+ hour, 11+ min ago  (578+ words) Until now, theories of light-matter interactions in nanoscale systems focused on how quickly energy *vanishes*; this work details how much energy remains, revealing a collective energy shift scaling as N. By analytically controlling both linewidth and energy shift, this provides a…...

2+ hour, 10+ min ago  (636+ words) Previously, generating coherent vibrational motion in multiple oscillators demanded a shared connection, limiting both scalability and precise control. Now, a new method achieves lasing through purely local driving within a quantum spin chain, creating individually addressable phonon lasers. This architecture…...

2+ hour, 38+ min ago  (962+ words) Previously, characterizing environmental effects on optomechanical resonators demanded confinement to a narrow frequency window around resonance. Now, a new model establishes a consistent pathway from locally-measured spectral properties to globally-defined open-system descriptions, overcoming this limitation. This advancement offers a complete…...
