Fig. 1: Demonstration of the coherence distribution.
From: Experimental study of quantum coherence decomposition and trade-off relations in a tripartite system
a Quantum coherence trade-off is described in tripartite systems with circles representing the qubits. The blue discs and red leaves represent the local coherence \({{{{\mathcal{C}}}}}_{{{{\rm{L}}}}}\) and the global coherence \({{{{\mathcal{C}}}}}_{{{{\rm{G}}}}}\). The strength of the color indicates the strength of the coherence. b A geometric picture of different coherences. Coherences are shown as distances between two different density matrices. ρ is the original density matrix; π(ρ) and [π(ρ)]d are as described in (5); \({\rho }_{1}={{{{\rm{tr}}}}}_{2,3}\,\rho\) and \({\rho }_{23}={{{{\rm{tr}}}}}_{1}\,\rho\) are the reduced density metrices.
