Generation of quantum states by the dynamics of spin chains: Analytical solution

2019 · Physical Review A

We design a quasi-one-dimensional spin chain with engineered coupling strengths such that the natural dynamics of the spin chain evolves a single excitation localized at the left-hand site to any specified single-particle state on the …

Quantum secret sharing and random hopping: Using single states instead of entanglement

2015 · Physical Review A

Quantum secret sharing (QSS) protocols between $N$ players, for sharing classical secrets, either use multipartite entangled states or use sequential manipulation of single $d$-level states only when $d$ is prime (A. Tavakoli et al., arXiv:1501.05582). …
