We propose and analyze a new approach for quantum state transfer between remote spin
qubits. Specifically, we demonstrate that coherent quantum coupling between remote qubits …

We characterize topological phases in photonic lattices by unveiling a formal equivalence
between the singular value decomposition of the non-Hermitian coupling matrix and the …

We propose a new fast scalable method for achieving a two-qubit entangling gate between
arbitrary distant qubits in a network by exploiting dispersionless propagation in uniform …

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 …

We address the time evolution of quantum correlations (QCs) such as entanglement, purity,
and coherence for a model of two non-interacting qubits initially prepared as a maximally …

We present a topological approach to the input-output relations of photonic driven-
dissipative systems acting as directional amplifiers. Our theory relies on a map** from the …

We consider a coupled-cavity array, where each cavity interacts with an atom under the
rotating-wave approximation. For a staggered pattern of intercavity couplings, a pair of field …

High-quality quantum-state and entanglement transfer can be achieved in an unmodulated
spin bus operating in the ballistic regime, which occurs when the endpoint qubits A and B …

Pretty good state transfer in networks of qubits occurs when a continuous-time quantum walk
allows the transmission of a qubit state from one node of the network to another, with fidelity …

Two different models are presented that allow for efficiently performing routing of a quantum
state. Both cases involve an XX spin chain working as a data bus and additional spins that …
