= Quantum t-design
{wiki=Quantum_t-design}
Quantum t-designs are mathematical structures in the field of quantum information theory that generalize the concept of classical t-designs. They are used to provide a way of approximating the properties of quantum states and quantum operations, particularly in the context of quantum computing and quantum statistics. In classical statistics, a **t-design** is a configuration that allows for the averaging of polynomials of degree up to t over a given distribution.
