Fidelity is symmetric in its arguments, i.e. F (ρ,σ) = F (σ,ρ). Note that this is not obvious from the original definition. F (ρ,σ) lies in [0,1], by the Cauchy–Schwarz inequality. F (ρ,σ) = 1 if and only if ρ = σ, since Ψ ρ = Ψ σ implies ρ = σ. So we can see that fidelity behaves almost like a metric.
We will assume for the moment that all state spaces of the systems considered, classical or quantum, are finite-dimensional. The memoryless in the section title carries the same meaning as in classical information theory: the output of a channel at a given time depends only upon the corresponding input and not any previous ones.
As it is, the average 65-year-old who retired in 2024 is expected to spend $165,000 on health care costs in retirement, according to Fidelity. But being on your own too much could add to that ...
In quantum mechanics, the exchange operator ^, also known as permutation operator, [1] is a quantum mechanical operator that acts on states in Fock space.The exchange operator acts by switching the labels on any two identical particles described by the joint position quantum state |, . [2]

High-fidelity data (HiFi) includes data that was produced by a person or Stochastic Process that closely matches the operational context of interest. For example, in wing design optimization, high-fidelity data uses physical models in simulation that produce results that closely match the wing in a similar real-world setting. [5]
The 50th season of "SNL" premiered last month. Since the first show in 1975, 165 comedians and actors have been a part of "SNL.". Three new comedians joined for season 50. "Saturday Night Live" is ...
