Spectral surgery and high-fidelity quantum state transfer in chains
Luc Vinet, Alexei Zhedanov
We consider an inhomogeneous spin chain which interpolates between the Krawtchouk one with perfect state transfer and the homogeneous chain. This model can be used to per…
Quantum State Transfer in Graphs with Tails
Pierre-Antoine Bernard, Christino Tamon, Luc Vinet +1
We consider quantum state transfer on finite graphs which are attached to infinite paths. The finite graph represents an operational quantum system for performing useful quantum in…
Entanglement of Free Fermions on Hamming Graphs
Pierre-Antoine Bernard, Nicolas Crampe, Luc Vinet
Free fermions on Hamming graphs are considered and the entanglement entropy for two types of subsystems is computed. For subsets of vertices that form Hamming subgraphs, a…
Perfect State Transfer in a Spin Chain without Mirror Symmetry
Gabriel Coutinho, Luc Vinet, Hanmeng Zhan +1
We introduce an analytical spin chain with asymmetrical transport properties. It has an even number of sites labeled by . It does not exhibit perfect state…
Quantum Fractional Revival on Graphs
Ada Chan, Gabriel Coutinho, Christino Tamon +2
Fractional revival is a quantum transport phenomenon important for entanglement generation in spin networks. This takes place whenever a continuous-time quantum walk maps the chara…
