High Fidelity State Transfer Over an Unmodulated Linear $XY$ Spin Chain
ORAL
Abstract
We provide a class of initial encodings that can be sent with a high fidelity over an unmodulated, linear, $XY$ spin chain. As an example, an average fidelity of 96\% can be obtained using an 11-spin encoding to transmit a state over a chain containing 10,000 spins. An analysis of the magnetic-field dependence is given, and conditions for field optimization are provided.
