We study the time evolution of mutual information (MI) and logarithmic negativity (LN) in two-dimensional free scalar theory with two kinds of time-de WitrynaThe logarithmic negativity quant-ph/0505071 is an entanglement measure which is easily computable and an upper bound to the distillable entanglement. It is defined as EN(ρ) : = log2∣∣ρΓA∣∣1 where ΓA is the partial transpose operation and ∣∣ ⋅ ∣∣1 denotes the trace norm. It relates to the negativity quant-ph/0102117 as follows: Witryna6 lut 2024 · If we defined the logarithmic negativity as E N ( ρ) = log 2 ‖ ρ Γ A ‖ 1 then given that ρ = 1 2 0 0 ⊗ + + + 1 2 + + ⊗ 1 1 = ( 1 / 4 1 / 4 0 0 1 / 4 1 / 2 0 1 … toyo all weather tires
