Metrics

A number of functions that can be used to quantify the properties of states such as entanglement are implemented. They are very straight-forward in terms of usage. For more information, see the list of functions below.

Functions

• tracenorm
• tracenorm_h
• tracenorm_nh
• tracedistance
• tracedistance_h
• tracedistance_nh
• entropy_vn
• fidelity
• ptranspose
• PPT
• negativity
• logarithmic_negativity

Examples

• Entanglement of Two Qubits
