WebNIST looks to the future to make sure we have the right cryptographic tools ready as new technologies are brought from research into operation. For example, NIST is now working on a process to develop new kinds of cryptography to protect our data when quantum computing becomes a reality. WebRecall that the adjoint of a complex matrix is the complex conjugate composed with the transpose (see terminology section for details). Hence, because a complex number can be considered as a single-entry matrix, its transpose is itself, so that its adjoint is its complex conjugate. In polar form, the complex
