Qiskit: Intro to Linear Algebra
In order to carry out quantum computations, we take a quantum state vector, and manipulate it by applying a matrix to it. A vector is simply a matrix that only has one column. To carry out this multiplication, we carry out the above procedure. We manipulate qubits by applying sequences of quantum gates, which can be expressed as matrices of elements that alter the states of qubits, such as the
