IBM Quantum System Services¶
The first and foremost quantum computing system services
for science and business.
Since 2016, when it made the world’s first quantum computer available through IBM Cloud®, IBM Quantum System Services has remained the premier place for researchers, industry professionals, developers, and students to access cutting-edge quantum hardware.
IBM Quantum offers both open and premium access to a wide variety of quantum systems. All quantum systems deployed by IBM Quantum are based on superconducting qubit technology, as the control and scalability of this technology pave a clear path to achieving quantum advantage with these systems.

About our systems
IBM Quantum System Services, based on IBM Quantum System One, are built using
world-leading quantum processors, cryogenic components, control electronics,
and classical computing technology.
These systems are denoted by
names that start with ibmq_*
. All systems return a configuration file
containing all the information needed for executing quantum circuits on the systems.
Additionally, quantum systems return properties information that details
the characteristics of the system qubits, as well as the gates acting on these qubits.
This includes noise information obtained from system calibration scripts.
Cite usage of a system
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:

Systems 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.
