- A separable if it can be approximated, in the trace norm, by states of the form
- When the state spaces are infinite-dimensional, density matrices are replaced by positive trace class operators with trace 1, and a state is separable if it can be approximated, in trace norm, by states of the above form.
- where the " w " i are positive-valued probabilities ( they sum up to 1 ), the vectors are unit vectors, and in the infinite-dimensional case, we would take the closure of such states in the trace norm.
- (The trace norm is the Schatten norm for " p " = 1 . ) The purpose of the factor of two is to restrict the trace distance between two normalized density matrices to the range [ 0, 1 ] and to simplify formulas in which the trace distance appears.
- For example, the Ky Fan-" k "-norm is the sum of first " k " singular values, the trace norm is the sum of all singular values, and the Schatten norm is the " p " th root of the sum of the " p " th powers of the singular values.
- It's difficult to find trace norm in a sentence. 用trace norm造句挺難的
