SpletThe trace defined as you did in the initial equation in your question is well defined, i.e. independent from the basis when the basis is orthonormal. Otherwise that formula gives rise to a number which depends on the basis (if non-orthonormal) and does not has much interest in physics.

SpletA linear combination of one basis of vectors (purple) obtains new vectors (red). If they are linearly independent, these form a new basis. The linear combinations relating the first basis to the other extend to a linear transformation, called the change of basis. A vector represented by two different bases (purple and red arrows).

SpletThe formula you are using for the trace only works if the $ i \rangle$ are orthonormal. In that case $\langle 1 0 \rangle = 0$ and your equation reduces to $0 = 0$, which is correct. – knzhou Oct 26, 2016 at 18:44 4 You should be careful with results in Dirac notation, because orthonormality is very often implicitly assumed. – knzhou Splet27. jul. 2024 · Trace operator is basis independent real-analysis functional-analysis 3,386 Solution 1 Suppose that { e n } and { f k } are orthonormal bases of H.
