Use this topic to ask your questions about the QHack 2023 challenge: A Pauli-Worded Problem
Hello,
I have some trouble with my mixmax_trace_dist function.
Here is my code
n = len(word)
rho = np.matrix(noisy_Pauli_density(word, lmbda))
max_mixed = np.matrix(1/2**n*np.eye(n))
return np.trace(abs_dist(max_mixed, rho))
I get the error ```
unsupported operand type(s) for -: ‘DensityMatrixMP’ and ‘float’. ‘’’
Even thought I converted both operands to np.matrix.
Thanks
Hi @yoshypdf ,
You need to change several things.
For starters I suggest you check out qml.pauli.PauliWord.
I hope this helps.
