The exponential of a matrix is defined by the Taylor Series expansion The basic reason is that in the expression on the right the A s appear before the B s but on the left hand side they can be mixed up. Expanding to second order in A and B the equality reads

Another familiar property of ordinary exponentials holds for the matrix exponential: If A and B commute (that is,), then You can prove this by multiplying the power series for the exponentials on the left. (is just with.) The matrix exponential plays an important role in solving system of linear differential equations. On this page, we will define such an object and show its most important properties. The natural way of defining the exponential of a matrix is to go back to the exponential function exand find a definition which is easy to extend to matrices.

Matrix exponentials are widely used to efficiently tackle systems of linear differential equations. To be able to solve systems of fractional differential equations, the Caputo matrix exponential As many operations in quantum computing involve performing matrix exponentials, this trick of transforming into the eigenbasis of a matrix to simplify performing the operator exponential appears frequently and is the basis behind many quantum algorithms such as Trotter–Suzuki-style quantum simulation methods discussed later in this guide. We now prove that this matrix exponential has the following property: deAt dt Verification of these properties is an excellent check of a calculation of eAt. This.

where we have de ned the \matrix exponential" of a diagonalizable matrix as: eAt= Xe tX 1 Note that we have de ned the exponential e t of a diagonal matrix to be the diagonal matrix of the e tvalues. Equivalently, eAtis the matrix with the same eigenvectors as A but with eigenvalues replaced by e t.
