Entanglement and quantum strategies reduce congestion costs in Pigou networks

Neural Networks and Quantum Entanglement

Strategies to reduce cancer-care costs.

P ayment for cancer care will change radically over the next decade as the nation struggles to hold down health care costs, experts told an early October Institute of Medicine forum, Delivering Affordable Cancer Care in the 21st Century. Traditional fee-for-service medicine, in which oncology reimbursement relies disproportionately on profits from expensive chemotherapy drugs, will give way to ...

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.

Voltage-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...

Entanglement percolation in quantum complex networks.

Quantum networks are essential to quantum information distributed applications, and communicating over them is a key challenge. Complex networks have rich and intriguing properties, which are as yet unexplored in the quantum setting. Here, we study the effect of entanglement percolation as a means to establish long-distance entanglement between arbitrary nodes of quantum complex networks. We de...
