Detailed Description

Immutable view of the reconstructed network state at one instant.

Returned by SimulationStateManager.snapshot_at(). This is the unit of state that the QuantumVisualizerWindow controller dispatches to the views, and the object a script inspects after reconstructing a chosen simulation time. Dynamic containers are copies or immutable views; advancing the manager afterwards never mutates an already-returned Snapshot.

Parameters

t_ns	Simulation timestamp this snapshot reflects.
nodes	Node topology (label -> Node), built once at load time.
channels	Channel list, built once at load time.
qubits	Every qubit created up to t_ns (label -> Qubit, with its current host node).
cbits	Every classical bit created up to t_ns (label -> ClassicalBit).
ent_graph	Entanglement-graph adjacency (label -> neighbor labels); vertices with no edges are omitted.
entangled_states	Entangled components of two or more qubits, keyed by the lexicographically smallest member (root -> sorted member tuple).
measured_qubits	Qubits measured at or before t_ns.
removed_qubits	Qubits explicitly removed from the simulation.
discarded_qubits	Qubits removed with reason == "discarded".
lost_qubits	removed_qubits - measured_qubits - discarded_qubits.
live_qubit_labels	Qubits neither measured nor removed.
inflight_qubits	Qubits in transit inside a sendQubit window.
inflight_cbits	Classical bits in transit inside a sendCbit window.
gate_qubits	Qubits inside an entangle processing window ([t_ns - duration_ns, t_ns); the edges commit at t_ns).
measuring_qubits	Qubits inside a measure duration_ns window.
graph_measuring_qubits	Qubits inside a graphMeasure duration_ns window.
removed_cbits	Classical bits removed by removeCbit.
