Entanglement in a quantum annealing processor

Lanting, T., Przybysz, A. J., Smirnov, A. Yu. et al.

Understand

Entanglement lies at the core of quantum algorithms designed to solve problems that are intractable by classical approaches.

One such algorithm, quantum annealing (QA), provides a promising path to a practical quantum processor.
We have built a series of scalable QA processors consisting of networks of manufactured interacting spins (qubits).
Here, we use qubit tunneling spectroscopy to measure the energy eigenspectrum of two- and eight-qubit systems within one such processor, demonstrating quantum coherence in these systems.
