Quantum Software

Quantum advantage requires innovation at every layer of the quantum stack. Our software team works alongside the hardware developers to build an expansive library of quantum circuits and to create programming tools so that anyone can develop their own quantum software.

Quantum Circuits and Software

We offer developers open-source tools to harness the power of quantum computing, as well as educational offerings and events. The Qiskit open-source SDK is the leading platform for quantum development worldwide, and its active quantum developer community is the largest in the world.

IBM Quantum has a clear vision toward achieving practical quantum advantage. Today we are building state-of-the-art superconducting quantum processors integrated into classical computing workflows, relying on the latest quantum science, cryogenic engineering, systems engineering, and industrial design.

Quantum Hardware

Quantum computing represents a paradigm shift in the types of problems we can solve. Getting it right requires deep understanding of the underlying theory. We’re exploring the fundamentals of quantum science, from entanglement and superposition to the development of novel quantum algorithms. 

Quantum Information Science

Cryptography enables the private, authenticated, and confidential communication that allows the internet to thrive. We’re researching quantum-safe cryptography, zero-knowledge proofs, and lattice-based cryptography, to secure everything from mainframes to the hybrid cloud.

Cryptography

Building the next generation of private, authenticated, and confidential communication cyrtopgraphy tools.
