Noncommutative metasurfaces enabled diverse quantum path entanglement of structured photons
Opto-Electronic ScienceQuantum entanglement, a fundamental concept in quantum mechanics, lies at the heart of many current and future quantum technologies. A pivotal task is the generation and control of diverse quantum entangled states in a more compact and flexible manner ...

Detecting quantum entanglement
Theoretical Computer Science, 2002 We review the criteria for separability and quantum entanglement, both in a bipartite as well as a multipartite setting. We discuss Bell inequalities, entanglement witnesses, entropic inequalities, bound entanglement and several features of multipartite entanglement.

A Quantum Router For The Entangled Web [PDF]
Information Systems Frontiers, 2019 Qubit transmission protocols are presently point-to-point, and thus restrictive in their functionality. A quantum router is necessary for the quantum Internet to become a reality. We present a quantum router design based on teleportation, as well as mechanisms for entangled pair management. The prototype was validated using a quantum simulator.

Entanglement purification on quantum networks
Physical Review Research, 2023 We present an approach to entanglement purification on complex quantum network architectures, that is, how a quantum network built from repeaters with limited processing fidelity can purify and distribute entanglement between users.

The Squashed Entanglement of a Quantum Channel [PDF]
IEEE Transactions on Information Theory, 2014 This paper defines the squashed entanglement of a quantum channel as the maximum squashed entanglement that can be registered by a sender and receiver at the input and output of a quantum channel, respectively. A new subadditivity inequality for the original squashed entanglement measure of Christandl and Winter leads to the conclusion that the ...

Electron-photon interaction in quantum dots : spin and entanglement [PDF]
, 2005 The interaction of electrons and photons lies at the heart of quantum physics. The most notable phenomena which are described by quantum physics but which obviously invalidate a classical description of the electromagnetic field - the photoelectric ...

Approximate encoding of quantum states using shallow circuits
npj Quantum InformationQuantum algorithms and simulations often require the preparation of complex states through sequences of 2-qubit gates. For a generic quantum state, the number of required gates grows exponentially with the number of qubits, becoming unfeasible on near ...

Quantum entanglement and topological entanglement [PDF]
New Journal of Physics, 2002 This paper discusses relationships between topological entanglement and quantum entanglement. Specifically, we propose that it is more fundamental to view topological entanglements such as braids as entanglement operators and to associate with them unitary operators that are capable of creating quantum entanglement.
