IBM Quantum systems overview¶
The first and foremost cloud-based quantum computing systems
and high-performance
simulators for research, industry, and education.
Since 2016, when it made the world’s first quantum computer available through IBM Cloud®, IBM Quantum Experience has remained the premier place for researchers, industry professionals, developers, and students to access cutting edge quantum hardware.
IBM Quantum currently hosts a wide variety of quantum systems, offering access through our open and premium 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.
Available systems: premium systems and open systems
What is a backend?
A backend is an interface to a quantum system
or classical quantum simulator.
A backend may be online or local and may support different types of experiments
(pulse schedule and/or circuit execution). Here we focus only on those backends
that are hosted on IBM Quantum Experience. These backends are denoted by
names that start with ibmq_*
. All backends return a configuration file
containing all the information needed for executing quantum circuits on the backend.
Additionally, real quantum systems return properties information that details
the characteristics of the device qubits, and the gates acting on these qubits.
This includes noise information obtained from device calibration scripts.
