Hi, I wanted to know how many qubits at max can pennylane’s lightning qubit simulator support on GPU device? Additionally, is there any detailed documentation on simulator backends and information on how many qubits each of it supports at maximum capacity?

Hi @kamzam and @kevinkawchak , The number of qubits you can run depends on many factors. Here are some important factors: The compute resources you have. Running circuits on a laptop is more limiting than running them in a server or a supercomputer. The depth of your circuit. If you have a very s…

Thank you @CatalinaAlbornoz , this was very helpful.

Thank you @kevinkawchak , I’ll go though this as well. :slight_smile:
