# FAQ

## QPU Data

### What's the 1Q/2Q native gate set?

The authoritative source of this information is the [Quil calibration program](https://docs.api.qcs.rigetti.com/#operation/GetQuiltCalibrations), which can be retrieved directly from the API or via utilities in `pyQuil` and other QCS tools.

If there's a `DEFCAL` for a gate, it's native; if not, you'll have to replace it prior to translation and execution. Note that:

* This native gate set changes over time
* A given gate may not be available on all qubits or edges within the topology of a QPU

### What are the 1Q/2Q gate times?

Like the native gate set, the source of truth for this information is the [Quil calibration program](https://docs.api.qcs.rigetti.com/#operation/GetQuiltCalibrations). Because the calibrations are shown for all native gates, the duration of a calibrated gate can be computed from the Quil implementation.

The gate time can usually be computed by hand, especially for simple gates. However, Quil utilities in [Rust](https://docs.rs/quil-rs/latest/quil_rs/program/analysis/struct.BasicBlock.html#method.as_schedule_seconds) and [Python](https://rigetti.github.io/quil-rs/quil/program.html#BasicBlock.as_schedule_seconds) can compute individual gate durations as well as the schedule of gates within an overall program. See the linked docs for examples.

### What are the 1Q/2Q operation fidelities?

This data is present within the [instruction set architecture](https://docs.api.qcs.rigetti.com/#operation/GetInstructionSetArchitecture) document available from the QCS API.

### What is the current T1, T2, or other benchmark?

Some benchmarks are available within the [instruction set architecture](https://docs.api.qcs.rigetti.com/#operation/GetInstructionSetArchitecture) document. However, some are left to the user to compute. For example, for practical reasons, we do not regularly publish T1 and T2 values for Ankaa QPUs.

### Does Ankaa support active reset?

As of May 2024, Ankaa QPUs support only passive reset. Active reset support arrives in mid-2024.
