IBM Quantum

Today, I am very proud to share Qiskit Fermions, a project that has been my major focus since the beginning of this year. Building this new toolbox has not only pushed me to become a better developer, but has also pushed what is possible to implement on top of the #Qiskit SDK itself. Writing a Rust-based extension linked against Qiskit's new C API and integrating with its new multi-representation compiler framework are just two such highlights. If you're working on fermionic systems in your research with quantum computers, be sure to give Qiskit Fermions a try and tell us about your experience!

Today, I'm excited to join Tanvi Gujarati as a co-host in our mini-symposium, "Pushing the Boundaries of Quantum Computing in Chemistry Towards Advantage”, at ACS Fall 2026: https://lnkd.in/dVawqZMH If you’re attending #ACS2026, join us as we explore both near-term opportunities and long-term visions for quantum advantage, followed by a panel discussion on practical applications, timelines, and defining success in this rapidly advancing field.

Introducing “Qiskit Fermions,” a new, open-source toolbox from IBM for expressing fermionic operators, constructing fermionic circuits, and defining mappings between fermionic and qubit systems: https://ibm.co/6040ERC20 Computing the properties of molecules and materials requires solving the quantum behavior of interacting 𝗳𝗲𝗿𝗺𝗶𝗼𝗻𝗶𝗰 𝗽𝗮𝗿𝘁𝗶𝗰𝗹𝗲𝘀, fundamental particles in nature bound by the laws of quantum mechanics. Quantum simulation of these systems is one of the most promising applications of quantum computing, but there is a gap between the fermionic problems researchers want to express and the qubit-based circuits a quantum computer actually runs. #Qiskit Fermions addresses this gap. By preserving fermionic structure through compilation and delaying fermion-to-qubit synthesis until transpilation, researchers can achieve a 𝗺𝗲𝗮𝗻𝗶𝗻𝗴𝗳𝘂𝗹 𝗿𝗲𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗶𝗻 𝗰𝗶𝗿𝗰𝘂𝗶𝘁 𝗱𝗲𝗽𝘁𝗵. This framework also enables advanced simulation workflows, including constant-depth 1D and 2D Fermi-Hubbard time dynamics. In our latest blog linked above, Max Rossmannek and Jennifer Glick from IBM Quantum detail the flexible modularity of Qiskit Fermions, the latest example of the “utility mapping tools” IBM is building to give researchers reusable software components that translate domain-specific problem descriptions into representations suitable for quantum computing.

Congratulations to my colleagues Jay Gambetta and Jerry M. Chow in IBM Research for this remarkable feature in Newsweek highlighting IBM’s advancements in quantum computing. The next frontier is using quantum, AI, and classical computing together to tackle challenges that were previously out of reach. From drug discovery to materials science and climate research, we’re beginning to see what useful quantum computing can make possible. Proud of the IBM researchers, engineers, and partners helping turn a long-held vision into practical impact. https://lnkd.in/gQ9eQznF

Your weekend assignment: Listen to The Coherence Times podcast ✅ In our latest episode, IBM Quantum cryogenics system engineers Matthew Hollister and Allie Lindler help us navigate the advanced cooling technology that makes superconducting quantum computing possible, diving deep into the infrastructure that houses, cools, and operates them. Together, they discuss why #cryogenic hardware matters, what goes into engineering refrigeration systems for quantum processors, and how our recently announced modular platform is designed to support the next generation of quantum computing systems.
