Graph Picture of Linear Quantum Networks and Entanglement

چکیده
The indistinguishability of quantum particles is widely used as a resource for the generation entanglement. Linear networks (LQNs), in which identical linearly evolve to arrive at multimode detectors, exploit generate various multipartite entangled states by proper control transformation operators. However, it challenging devise suitable LQN that carries specific state or compute possible given particle and mode number increase. This research presents mapping process arbitrary LQNs graphs, provides powerful tool analyzing designing We also introduce perfect matching diagram (PM diagram), refined directed graph includes all essential information on entanglement an LQN. PM furnishes rigorous criteria solid guidelines genuine Based structure diagrams, we compose fundamental N-partite genuinely states.

Quantum Networks for Concentrating Entanglement
If two parties, Alice and Bob, share some number, n, of partially entangled pairs of qubits, then it is possible for them to concentrate these pairs into some smaller number of maximally entangled states. We present a simplified version of the algorithm for such entanglement concentration, and we describe efficient networks for implementing these operations.
متن کاملVoltage-Controlled Entanglement between Quantum- Dot Molecule and its Spontaneous Emission Fields via Quantum Entropy
The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...

15 صفحه اولMatter‐matter entanglement for quantum networks
Developments in quantum information science rely critically on entanglement, as its distribution between different parties enables quantum communication protocols, such as quantum key distribution or teleportation. This talk focused on two different ways to generate heralded entanglement between matter systems, a critical reqiurement for scalable quantum networking.
