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 …

We turn now to the description of the building blocks of quantum information theory. We
introduce the quantum analog of the bit—qubit, single-and multiple-qubit logic gates and …

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

We propose a fast and robust quantum state transfer protocol employing a Su-Schrieffer-
Heeger chain, where the interchain couplings vary in time. Based on simple considerations …

We demonstrate that perfect state transfer can be achieved using an engineered spin chain
and clean local end-chain operations, without requiring the initialization of the state of the …

We suggest a scheme that allows arbitrarily perfect state transfer even in the presence of
random fluctuations in the couplings of a quantum chain. The scheme performs well for both …

We consider a one-dimensional gas of cold atoms with strong contact interactions and
construct an effective spin-chain Hamiltonian for a two-component system. The resulting …

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 …

An exactly-solvable model for the decay of a metastable state coupled to a semi-infinite, tight-
binding lattice, showing large deviations from exponential decay in the strong coupling …

Repulsively interacting particles in a periodic potential can form bound composite objects,
whose dissociation is suppressed by a band gap. Nearly pure samples of such repulsively …
