# Is it possible to set quantum volume in IBM Quantum simulator?

A quantum volume serves as a metric of a quantum processor quality. So far, IBM Quantum provides processors with quantum volume up to 128. Freely accessbile processors have QV up to 32. A user using free access can employ fake processors (see details here) to simulate behavior of her/his circuits on processor with QV higher than 32.

However what about simulation of processors with QV above 128? Is it possible to somehow set qasm_simulator to behave like a processor with given quantum volume?

Bear in mind that if you operate on a subset of $$n$$ qubits, then your QV is at most $$2^n$$. Hence the answer below assumes that you'd like to experiment with a simulator that has $$n$$ qubits but some $$QV = 2^m$$ where $$m < n$$.
• Thank you for the answer. However, QV is more or less $2^n$, not $n^2$, right? Dec 20, 2021 at 7:24
