hello,

yes ... especially if you want to execute quantum-circuits which use a lot of qubits.

why!? one approach of the simulation of quantum-computers rely on the so called "state vector" of the machine, and its memory-usage grows exponentially.

for example qiskit AER

* https://qiskit.github.io/qiskit-aer/stubs/qiskit_aer.Stateve...

just as an example:

for 32 qubits, the simulator needs 64 GB RAM

=?> double the RAM for each additional qubit

so: for 36 qubits, the simulator needs 1 TB RAM

:)

so it gets pretty "costly" to do simulations rather quickly ...
