A state-vector simulator stores 2ⁿ complex amplitudes; a QPU holds n Qubits but cannot reveal all amplitudes in one measurement.
The state-vector memory wall
Watch classical simulation memory double with every added Qubit.
01 · Set up the comparison
Choose a workload and scale
See why simulating quantum state on classical hardware becomes difficult.
Workloads
Choose what kind of work to test
Workload is what the machine does; scale is how much. Choosing one loads a starting scale.
Number of Qubits

Changing the scale keeps this workload. Choose another card above to change workloads.
Test question
When does the classical state-vector approach become the bottleneck?
