Quantum Device Module

This module provides types for modeling quantum hardware devices. It includes device topology, qubit layout mapping, noise models, and execution result handling.

Key Components

• Device: Quantum device specification with qubit and edge properties
• Topology: Device connectivity graph
• Layout: Logical to physical qubit mapping
• NoiseModel: Noise simulation parameters
• ExecutionResult: Measurement outcome collection

Instruction capability semantics

Topology describes directed physical connectivity only; a coupling edge does not by itself name the instructions executable on that edge. Device::native_gates is the device-wide default capability set. A qubit or directed edge with no local native instructions inherits the matching one- or two-qubit defaults. A non-empty local native-instruction list is a complete override for that physical location.

Local capabilities are never synchronized back into the device defaults, and replacing the defaults does not remove local capabilities. Two-qubit capabilities are ordered: support on (control, target) does not imply support on (target, control). Calibration data describes a supported instruction but does not create support for an otherwise unsupported one.

Native capability writers validate their inputs and return DeviceError. Device defaults accept standard gates acting on at most two qubits, while qubit and edge properties accept exactly one- and two-qubit standard gates, respectively. Validation completes before mutation, so a rejected update preserves the previous capability set.
