We review the subject of perfect state transfer—how one designs the (fixed) interactions of a
chain of spins so that a quantum state, initially inserted on one end of the chain, is perfectly …

The transfer of data is a fundamental task in information systems. Microprocessors contain
dedicated data buses that transmit bits across different locations and implement …

One of the ambitious goals of artificial intelligence is to build a machine that outperforms
human intelligence, even if limited knowledge and data are provided. Reinforcement …

Network theory has played a dominant role in understanding the structure of complex
systems and their dynamics. Recently, quantum complex networks, ie collections of quantum …

Faithful communication is a necessary precondition for large scale all-optical networking
and quantum information processing. Related theoretical investigations in different areas of …

Perfect transfer of a quantum state through a one-dimensional chain is now well understood,
allowing one not only to decide whether a fixed Hamiltonian achieves perfect transfer but to …

We examine the speed and fidelity of several protocols for state or single excitation transfer
in finite spin chains subject to diagonal and off-diagonal disorder. We find that, for a given …

Quantum state transfer in the presence of static disorder and noise is one of the main
challenges in building quantum computers. We compare the quantum state transfer …

Quantum state transfer between distant nodes is at the heart of quantum processing and
quantum networking. Stimulated by this, we propose a scheme where one can achieve …

Spin chains with site dependent exchange coefficients can achieve near perfect quantum
state transfer for Hamiltonians with nearest neighbors XXZ type interactions without external …
