Local quantum Fisher information and one-way quantum deficit in spin-$\frac{1}{2}$ $XX$ Heisenberg chain with three-spin interaction

Abstract

We explore quantum phase transitions in the spin-1/2 $XX$ chain with three-spin interaction in terms of local quantum Fisher information and one-way quantum deficit, together with the demonstration of quantum fluctuations. Analytical results are derived and analyzed in detail.
