Towards Highly Storage Efficiency of Optical Quantum Memory Based on Electromagnetically Induced Transparency Protocol

Towards Highly Storage Efficiency of Optical Quantum Memory Based on Electromagnetically Induced Transparency Protocol
Long-distance quantum communication based on quantum repeater protocol [more]
Schrödinger's famous cat Gedankenexperiment investigates how the laws of quantum mechanics extend into the macroscopic realm. An experimentally accessible model system in quantum optics is the superposition of two well-distinguishable coherent states - a so-called "cat state" - with a tunable degree of macroscopicity. Applying a high-finesse cavity we demonstrate a new method to create flying optical cat states. They are entangled to a single trapped atom, much like Schrödinger's original cat. I show control over various degrees of freedom of the cat states, which is a great asset for their potential application to continuous-variable quantum computing. [more]
