👉 An invited fluid is a term used in the context of quantum computing and quantum information theory, referring to a specific type of quantum state that is prepared in a controlled manner by adding an external field (such as an electromagnetic field) to a system of qubits. Unlike the ground state, which is the lowest energy state of a quantum system, an invited fluid has a well-defined, low-energy configuration that can be manipulated and entangled with other quantum states. This state is "invited" because it requires the presence of an external field to form and maintain its structure, distinguishing it from other quantum states that do not depend on external parameters. Invited fluids are crucial for implementing quantum gates and operations in quantum computing architectures, as they allow for precise control over qubit interactions.
