Automates IBM Quantum backend connection, authentication, and selection by detecting your subscription plan and returning the least-busy available QPU resource for immediate use in Qiskit circuits.
However, note the aging maintenance status (219 days since last release) and verify that the connector's error handling and backend-selection logic align with your…
Qiskit Experiments provides tools for building, running, and analyzing experiments on noisy quantum computers using the Qiskit framework.
Provides a Python client to access IBM Quantum Compute (formerly Qiskit Runtime), enabling execution of quantum circuits on IBM quantum hardware with built-in error suppression and mitigation.
Install it if you have IBM Quantum Platform or IBM Cloud access and want to execute real quantum computations.
Qiskit IonQ Provider enables submission of quantum circuits to IonQ's ion trap quantum systems and simulators through the Qiskit SDK, using IonQ's REST API with an access token.
Converts OpenQASM 3 programs (as strings) into Qiskit QuantumCircuit objects, enabling quantum circuit construction from OpenQASM 3 source code.
However, note that the authors explicitly position this as a temporary solution pending technical decisions—expect the API or feature coverage to potentially change.
Qiskit Terra provides the core SDK for building and executing quantum circuits, operators, and primitive functions on quantum computers and simulators.
However, the package is officially deprecated in favor of the qiskit meta-package (recommended for new projects).
SDK for controlling Quantum Machine's Octave hardware using QUA, communicating via gRPC with protobuf serialization.
QM-QUA is a Python SDK that implements QUA, a pulse-level language for controlling quantum computers via Quantum Machines' OPX controller hardware.
Install only if you need to control quantum systems via Quantum Machines hardware; it is not a general-purpose quantum simulator.
A Python wrapper for the QOI (Quite OK Image) lossless image format that encodes and decodes images as numpy arrays, offering faster compression and decompression than PNG with comparable file sizes.
QONNX provides Python utilities to work with quantized neural networks in ONNX format, including custom operators for arbitrary-precision integer and minifloat quantization, model execution, shape inference, and inference cost analysis.
