Struct QuantumLocomotionState 

pub struct QuantumLocomotionState {
    pub rho: DensityMatrix5,
    pub hamiltonian: LocomotionHamiltonian,
    pub kernels: InterferenceKernels,
    pub phase_time: f32,
    pub frame: u64,
}

Full quantum locomotion state — wraps density matrix, Hamiltonian, kernels. This is the quantum simulation subsystem that satisfies QUANTUM.md S11.

Fields

rho: DensityMatrix5

The density matrix rho in C^{5x5}.

hamiltonian: LocomotionHamiltonian

The Hamiltonian governing coherent evolution.

kernels: InterferenceKernels

Interference kernels for particle rendering.

phase_time: f32

Cumulative phase time (for H_phase).

frame: u64

Frame counter for measurement seed.

Implementations

impl QuantumLocomotionState

pub fn new(particle_count: u32) -> Self

pub fn tick( &mut self, dt: f32, input_bias: &[f32; 5], decoherence_epsilon: f32, ) -> usize

Tick the quantum locomotion state.

1. Build input bias from player state
2. Hamiltonian evolution (unitary)
3. Decoherence channel (terrain/contact)
4. Returns Born-rule measured mode

pub fn particle_position_with_interference( &self, n: usize, root: [f32; 3], mode_templates: &[[f32; 3]; 5], ) -> [f32; 3]

Compute particle position with interference. pos = root + sum_k rho_kk * g_{n,k} + interference_displacement(n)
