Entangled En Masse: Physicists Crank Out Billions of Entangled Nucleus-Electron Pairs on Demand

Entanglement, that most counterintuitive quantum phenomenon by which particles share an unseen link that aligns their properties, is looking more mundane all the time. Just last week two groups of researchers reported entangling a photon with a crystal-based device, potentially paving the way for solid-state memories that can store and then release entangled particles as needed.

The mysterious phenomenon known as quantum entanglement - where objects seemingly communicate at speeds faster than light to instantaneously influence one another, regardless of their distance apart - was famously dismissed by Einstein  as "spooky action at a distance." New experiments could soon answer skeptics by enabling people to see entangled pulses of light with the naked eye.

Title: Energy-Entanglement Relation for Quantum Energy Teleportation
Authors: Masahiro Hotta

Protocols of quantum energy teleportation (QET), while retaining causality and local energy conservation, enable the transportation of energy from a subsystem of a many-body quantum system to a distant subsystem by local operations and classical communication through ground-state entanglement. We prove two energy-entanglement inequalities for a minimal QET model. These relations help us to gain a profound understanding of entanglement itself as a physical resource by relating entanglement to energy as an evident physical resource.

Caltech Physicists Propose Quantum Entanglement for Motion of Microscopic Objects

Researchers at the Caltech have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. Their ideas, described in the early online issue of the Proceedings of the National Academy of Sciences, offer a new means of addressing one of the most fascinating issues in quantum mechanics: the nature of quantum superposition and entanglement in progressively larger and more complex systems.

Teleportation
Inching our reality ever closer to Star Trek's, scientists at the University of Maryland's Joint Quantum Institute successfully teleported data from one atom to another in a container a meter away.

Cold-atom experiments show chaotic fingerprints in the quantum world.
A hidden partnership between two of the hottest topics in physics - quantum entanglement and chaos theory - may have been uncovered by a series of ingenious experiments with caesium atoms. The relationship could provide clues about where the quantum realm ends and the classical world begins.

Quantum Entanglement Visible to the Naked Eye
By linking the electrical currents of two superconductors large enough to be seen with the naked eye, researchers have extended the domain of observable quantum effects. Billions of flowing electrons in the superconductors can collectively exhibit a weird quantum property called entanglement, usually confined to the realm of tiny particles, scientists report in the September 24 Nature.

Scientists have "entangled" the motions of pairs of atoms for the first time.

Entanglement is an effect in quantum mechanics, a relatively new branch of physics that is based more in probability than in classical laws.

It describes how properties of two or more objects can be inextricably linked over "vast" distances.

The idea that far distant particles can somehow 'talk' to each other worried Einstein so much that he called it 'spooky action at a distance'.
Having confirmed its existence, scientists today are learning how to use this 'spooky action' as a helpful tool.  Now a team of physicists at the University of Bristol and Imperial College London have harnessed this phenomenon to shed light on another unusual and previously difficult aspect of quantum physics - that of distinguishing between two similar quantum devices.
