Quantum entanglement goes large Quantum entanglement occurs when two separate entities become strongly linked in a way that cannot be explained by classical physics; it is a powerful resource in quantum communication protocols and advanced technologies that aim to exploit the enhanced capabilities of quantum systems. To date, entanglement has generally been limited to microscopic quantum units such as pairs or multiples of single ions, atoms, photons, and so on. Kotler et al. and Mercier de L… 
Quantum mechanics–free subsystem with mechanical oscillators
TLDR
It is shown how it is possible to measure an oscillator without quantum back-action of the measurement by constructing one effective oscillator from two physical oscillators by realizes such a quantum mechanics–free subsystem using two micromechanical oscillators, and shows the measurements of two collective quadratures while evading the quantumBack-action on both of them.
Quantum entanglement: Bell's inequality trivially violated also classically
Quantum entanglement manifests in the perfect correlation between particles or photons separated by space and time beyond causal interference. However, classical covariance between vectorial

Deterministic entanglement of separated mechanical oscillators is demonstrated, consisting of the vibrational states of two pairs of atomic ions held in different locations, and quantum entanglements in a degree of freedom that pervades the classical world are shown.
