Particles small enough for their behaviour to be governed by the laws of quantum mechanics can exhibit a remarkable property known as entanglement. A pair of quantum particles can exist in entangled 'superposition', a mixture of states that resolves only when some physical property such as spin or polarization is measured. Quantum entanglement is a fundamental requirement for quantum computing, but until now it has been possible only to generate entanglement between microscopic particles. Using a new method of generating entanglement, an entangled state involving two macroscopic objects, each consisting of a caesium gas sample containing about 1012 atoms, has now been created. The entangled spin state can survive for 0.5 milliseconds, a long time in this context, bringing practical applications of quantum memory and quantum teleportation a little closer.

anyone have more on this? like how.
