qcloud Module

pyqpanda3.qcloud covers remote execution, backend discovery, calibration metadata, and cloud result handling.

Main types

Type	Role
QCloudService	Authenticate and discover backends.
QCloudBackend	Submit programs, instructions, tomography jobs, or expectation jobs.
QCloudJob	Track task state and fetch results.
QCloudResult	Read parsed outputs plus optional raw service fields.
QCloudOptions	Control cloud-side mapping, optimization, amendment, and custom flags.
QCloudNoiseModel	Configure noisy simulator execution.
ChipInfo	Inspect chip topology, timing, and fidelity metadata.

0.4.0 workflow additions

• QCloudJob.query() and QCloudJob.result() can request extra raw fields through keys= or key=.
• QCloudResult now exposes raw-field helpers such as mapping_qprog(), mapping_qubit(), src_qubits(), and prob_count_raw().
• QCloudBackend.chip_backend() provides a direct bridge to pyqpanda3.transpilation.ChipBackend.
• best_qubit_blocks() is available from both QCloudService and QCloudBackend.

Enumerations

Enum	Description

DataFormat	Circuit export data format. Avoid the internal pyqpanda3.qcloud.qcloud import path in new code.
DataBase	Binary or hex formatting for result states.
NOISE_MODEL	Cloud noise model types.
LogLevel	Logging verbosity.
