The following pages are resources for anyone interested in contributing code to Qiskit.
Other discussions
Discuss quantum information science and development with the larger quantum computing field on the Quantum Computing Stack Exchange site. Be sure to read the "How do I ask a good question?" guide, and make use of tags such as qiskit, ibm-runtime, and ibm-quantum-services for best results.
For questions specific to programming, visit Stack Overflow and use the tag qiskit.

For research papers, we encourage authors to acknowledge IBM Quantum using:
We acknowledge the use of IBM Quantum services for this work. The views expressed are those of the authors, and do not reflect the official policy or position of IBM or the IBM Quantum team.
Paper references should be cited as follows:
IBM Quantum. https://quantum.ibm.com/, 2021
Quantum processing units in the paper should be referenced by their unique name (i.e., ibmq_vigo) and optionally
adding the version (i.e., ibmq_vigo v1.0.2). We also encourage referencing the processor.
For example:
In this paper we used
ibmq_vigo, which is one of the IBM Quantum Canary processors.

Why do I receive the error message AttributeError: QuantumCircuit object has no attribute 'save_state' when using save_*method on a circuit?
Why do I receive the error message AttributeError: QuantumCircuit object has no attribute 'save_state' when using save_*method on a circuit?
The save_* instructions are part of Qiskit Aer project,
a high performance simulator for quantum circuits. These instructions do not
exist outside of Qiskit Aer and are added dynamically to the
QuantumCircuit class by Qiskit Aer on import. If you would like to
use these instructions you must first ensure that you have imported
qiskit_aer in your program before trying to call these methods. You
can refer to qiskit_aer.library for the details of these custom
instructions included with Qiskit Aer.
Why do my results from real devices differ from my results from the simulator?
Why do my results from real devices differ from my results from the simulator?
The simulator models an ideal environment, without noise or decoherence. When jobs are run on the real devices, noise from the environment and decoherence cause the qubits to behave differently than in an ideal environment.
