Get a sparse matrix of quantum circuit

Is there a way that can obtain sparse matrix of quantum circuit? I used to check my quantum circuit with quantum_info.Operator, but for large number of qubits, it is difficult because of the memory allocation limit. Is it available in qiskit? or should I build elementary gates in sparse matrix format? Thank you!

• Sorry, I misused the word. I mean the quantum circuit cannot be converted to matrix because of the large size of matrix.

• As an extreme example consider $H^{\otimes n}$. Dec 8 '20 at 2:41
