Does it cost anything to run PennyLane on Open Quantum?

No. During beta, jobs on PennyLane run on the Public Compute tier with no credits used. You can prototype and debug as much as you need before spending anything on real hardware.

Which simulation methods are available with PennyLane?

Methods: State vector, mixed state, and Clifford. Noise modeling: Noiseless simulation.

How do I run a circuit on PennyLane?

Create a free Open Quantum account, write your circuit in any supported framework, and select the PennyLane backend in the job builder. Open Quantum handles the translation, so there is no separate Xanadu setup to manage.

Can I run the same circuit on real hardware?

Yes. The same code you run on PennyLane runs unchanged on real QPUs from IonQ, Rigetti, IQM, and AQT, with $50 of free quantum compute to start.

About PennyLane

PennyLane Lightning is Xanadu’s high-performance simulator suite for the PennyLane ecosystem. PennyLane is one of the most widely used quantum frameworks, and surveys report that nearly a third of quantum developers use it. Lightning’s core is written in C++ for speed, it is open source under the Apache 2.0 license, and it installs alongside PennyLane itself, so it is the high-performance simulator most PennyLane developers already have. On Open Quantum, Lightning’s CPU state vector is the default, alongside PennyLane’s built-in default.qubit, default.mixed, and default.clifford devices. Submit circuits from any supported framework, then run the same code, unchanged, on real QPUs when you are ready.

Configuring PennyLane

Options you can set when you create a job on PennyLane.

engine

Which PennyLane device runs your circuit, all on CPU: the Lightning state vector (lightning.qubit, the default), the default state vector (default.qubit), mixed state (default.mixed, a density matrix for noisy circuits), or Clifford (default.clifford, only correct for Clifford circuits).
