Class Result

com.quantum4j.core.backend.Result

public final class Result
extends Object

Immutable container for quantum circuit execution results.

Stores measurement outcome counts from multiple circuit executions (shots). Each key is a classical bit string (e.g., "110") and each value is the number of times that outcome was measured across all shots.
