Quantum channel is a planned ScholarlyWiki page in the Quantum Collection about quantum channels and open-system transformations.

Overview

Placeholder: introduce quantum channels as completely positive trace-preserving maps that describe physical transformations of quantum states.

Key ideas

Placeholder: cover density matrices, open systems, completely positive maps, trace preservation, noise models.

Definition

Placeholder: develop this section with definitions, examples, formulas, and links to related Quantum Collection pages.

Physical meaning

Placeholder: develop this section with definitions, examples, formulas, and links to related Quantum Collection pages.

Examples of channels

Placeholder: develop this section with definitions, examples, formulas, and links to related Quantum Collection pages.

Role in open quantum systems

Placeholder: develop this section with definitions, examples, formulas, and links to related Quantum Collection pages.
