Struct Device 

pub struct Device {
    pub a_pi_fx: i64,
    pub seed: u64,
}

A single driven qubit under a Rabi model. The calibrator does not see a_pi_fx — it is the hidden truth the tune-up must discover.

Fields

a_pi_fx: i64

The true π-pulse amplitude (fixed-point) — hidden from the calibrator.

seed: u64

A per-device stream seed, so two devices with the same a_pi still shot- noise independently but each reproducibly.

Implementations

impl Device

pub fn excited_prob(&self, a_fx: i64) -> i64

Exact excited-state probability at drive amplitude a: P(a) = sin²(π·a / (2·a_π)). Pure integer.

pub fn measure(&self, a_fx: i64, shots: u32) -> i64

One “experiment”: shots projective measurements at amplitude a, returning the measured excited fraction (fixed-point). Deterministic Bernoulli sampling via splitmix64 keyed by (seed, a), so the shot noise is real but portable.
