@inproceedings{Horodecki2007QuantumE, title={Quantum entanglement}, author={Ryszard Horodecki and Paweł Horodecki and Michal Horodecki and Karol Horodecki}, year={2007} }

All our former experience with application of quantum theory seems to say that what is predicted by quantum formalism must occur in the laboratory. But the essence of quantum formalism— entanglement, recognized by Einstein, Podolsky, Rosen, and Schrödinger—waited over 70 years to enter laboratories as a new resource as real as energy. This holistic property of compound quantum systems, which involves nonclassical correlations between subsystems, has potential for many quantum processes…

### Measuring entanglement entropy in a quantum many-body system

- PhysicsNature
- 2015

Making use of the single-site-resolved control of ultracold bosonic atoms in optical lattices, two identical copies of a many-body state are prepared and interfered to directly measure quantum purity, Rényi entanglement entropy, and mutual information.

### Mediation of entanglement and nonlocality of a single fermion

- PhysicsQuantum Inf. Process.
- 2018

This work proposes a method to create entanglement between two distant fermionic particles, which never interact directly by using a third fermion to mediate the correlation, and demonstrates that bipartite maximally entangled states can be generated with an efficiency of about 56%.

Decoherence is the physical process by which the classical world - the world of common sense - emerges from its quantum underpinnings. This physical process refers to the loss of phase coherence…

### General Paradigm for Distilling Classical Key From Quantum States

- Computer ScienceIEEE Transactions on Information Theory
- 2009

It is demonstrated that all quantum cryptographic protocols can be recast in a way which looks like entanglement theory, with the only change being that instead of distilling Einstein-Podolsky-Rosen (EPR) pairs, the parties distill private states.

### On the role of entanglement in quantum-computational speed-up

- Physics, Computer ScienceProceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences

It is argued that it is nevertheless misleading to view entanglement as a key resource for quantum‐computational power, as it is necessary for any quantum algorithm to offer an exponential speed‐up over classical computation.
