Why IBM Quantum

Ideal quantum state

Test circuits with no noise and arbitrary connectivity


Rapidly prototype circuits for use with real IBM quantum hardware

Characterize noise response

Add exactly the type and strength of noise whose effects you want to study

Access IBM simulators in different ways

IBM offers a high-performance simulation framework called Qiskit Aer for the open source Qiskit software stack. Qiskit is the most modular and extensible tool for leveraging today's quantum processors in research, education, and business. Explore and optimize solutions that aren’t yet possible on today’s hardware
