Density Matrix
A mathematical tool in quantum mechanics for describing mixed states. It is a generalization of the wave function, used to represent a system as a probabilistic combination of multiple pure states, and is common in noise and decoherence scenarios.
Timeline (last 90 days)
In a system of dimension d, fully describing the density matrix requires d²−1 real parameters.
The density matrix is a generalized form of the wave function, used to describe mixed states—that is, probabilistic combinations of the system being in multiple pure states, commonly seen in situations involving noise, decoherence, or coupling with the external environment.
