Frequently Asked Questions

What is the difference between Pasqal Fresnel and QuEra Aquila?

Both QPUs have comparable 2Q gate fidelity (~99.50%). QuEra Aquila offers more physical qubits (256 qubits).

Which is better for quantum chemistry, Pasqal Fresnel or QuEra Aquila?

For quantum chemistry simulations (VQE, UCCSD), Pasqal Fresnel is preferred due to its higher 2Q gate fidelity (99.50% vs 99.50%). Higher gate fidelity directly reduces circuit error rates in chemistry algorithms.

How do the prices compare between Pasqal Fresnel and QuEra Aquila?

Pasqal Fresnel is available from $0.00/shot on Azure Quantum. QuEra Aquila is available from $0.0100/shot on Amazon Braket. Note that pricing models differ — per-shot pricing is directly comparable while AQT and HQC models depend on circuit structure.

Which QPU has better connectivity, Pasqal Fresnel or QuEra Aquila?

Both Pasqal Fresnel and QuEra Aquila use Custom connectivity. The effective connectivity degree is N/A for Pasqal Fresnel and N/A for QuEra Aquila.

What are the coherence times for Pasqal Fresnel vs QuEra Aquila?

Pasqal Fresnel: T1=4 ms, T2=1 ms. QuEra Aquila: T1=5 ms, T2=1.5 ms. QuEra Aquila has longer coherence times, which generally allows for deeper circuits before errors accumulate.
