//! This module supports experimental features that meet the following criteria:
//!
//! * They support recent and compelling research in quantum computing.
//! * Implementation is specific to Rigetti's QPUs; implementation may
//! not othewrise be expressed through a generalized quantum computing
//! language, such as Quil or QASM.
//!
//! As such, the features contained herein should be considered unstable, possibly
//! ephemeral, and subject to specific authorization checks.
