Heron r3 & Nighthawk for deeper circuits

Target deeper, more demanding circuits on IBM’s latest QPUs. Heron r3 delivers low error rates for complex hybrid workflows. Nighthawk’s square-lattice connectivity enables new kinds of experiments, like a recent study using 2D disordered Heisenberg‑model simulations to examine the thermalization of isolated quantum many‑body systems.

Additional updates

Introducing Qiskit Fermions

Qiskit Fermions is a new quantum chemistry library that extends Qiskit with tools for fermionic systems. Use built‑in fermionic mappers, operator tools, and an extensible circuit‑synthesis library—or build your own mappers and circuits with Python or the C API.

Tutorial: Low-overhead error detection with spacetime codes

Try out a novel method that uses spacetime codes to detect errors, balancing the accuracy of fault-tolerant error correction protocols with the lighter-weight computational cost of error mitigation.

Qiskit Functions add real-time logs

Real-time execution logs provide visibility into execution stages, applied optimizations, and job metadata. Use `job.logs()` to monitor progress, debug failures faster, and analyze how Functions run—while they're running. Try it now in the Quantum Portfolio Optimizer Function, more soon.
