According to Xanadu‘s published benchmarks, Lightning simulators scale to 1,000+ AMD GPUs with strong scaling via Kokkos, demonstrated on Oak Ridge’s Frontier supercomputer.
PennyLane supports hardware from IonQ (via Qiskit/Cirq plugins), Rigetti, D-Wave, AWS Braket, and IQM through hardware-agnostic APIs. In 2025, PennyLane’s Catalyst compiler integrated with Open Quantum Design’s trapped-ion hardware control signals, enabling quantum frontends to compile directly to hardware instructions – described by Xanadu and Open Quantum Design as the first fully open-source quantum computing stack from software to hardware.
