Template:Unreferenced stub A quantum register (also known as a qregister) is the quantum mechanical analogue of a classical processor register.
A mathematical description of a quantum register is achieved by using a tensor product of qubit bra or ket vectors. For example, an n qubit quantum register is described by an element in the tensor product Hilbert space
