Transitions in Entanglement Complexity in Random Circuits [PDF]
Entanglement is the defining characteristic of quantum mechanics. Bipartite entanglement is characterized by the von Neumann entropy. Entanglement is not just described by a number, however; it is also characterized by its level of complexity.

The causes and consequences of the properties of a particle and a wave are presented, during the passage of a quantum of space-matter of an electron, a photon, through one and two slits.

Topologically protected quantum entanglement emitters
Entanglement and topology portray nature at the fundamental level but differently. Entangled states of particles are intrinsically sensitive to the environment, whereas the topological phases of matter are naturally robust against environmental ...

Detecting a Target With Quantum Entanglement [PDF]
Over the last decade, research activity has focused on the use of quantum entanglement as a resource for remote target detection, i.e., on the design of a quantum radar.

Cost of quantum entanglement simplified [PDF]
Quantum entanglement is a key physical resource in quantum information processing that allows for performing basic quantum tasks such as teleportation and quantum key distribution, which are impossible in the classical world.

The Effect of Quantum Noise on Multipartite Entanglement from a Cascaded Parametric Amplifier
The tripartite entanglement generated from a cascaded parametric amplifier is always present in the whole gain region in the ideal condition. However, in practical applications, the quantum entanglement is very fragile and easily deteriorated by quantum ...

Cloning of Quantum Entanglement [PDF]
Quantum no-cloning, the impossibility of perfectly cloning an arbitrary unknown quantum state, is one of the most fundamental limitations due to the laws of quantum mechanics, which underpin the physical security of quantum key distribution. Quantum physics does allow, however, approximate cloning with either imperfect state fidelity and/or ...
