Rahko presents the results from its latest Quantum Processing Unit (QPU) implementation, in a collaboration with Johnson Matthey and Honeywell Quantum Solutions.

Using Rahko’s Discriminative Variational Quantum Eigensolver (‘DVQE’), they have reached groundbreaking accuracy on Honeywell’s latest QPU, System Model HØ, giving strong early indication of the powerful capability quantum computing will offer for the computation of electronic structure.

Examples of particularly promising application areas include photo-electrochemical reduction of CO2, low-T ammonia synthesis, and enhanced understanding of enzyme function in photosynthesis.

The Honeywell System Model HØ offers a 6-qubit quantum register with outstanding gate fidelities, achieving a total quantum volume of 64, which puts it among the forefront of QPUs of its generation.

With the benefit of the device’s low error rates and a fully connected set of qubits, Rahko has used its DVQE method (a fully variational method) to reach groundbreaking accuracy in the first excited state of a 4-qubit molecule on Honeywell’s System Model H0. 

The DVQE method was combined with light-touch error mitigation techniques that are able to further improve results on near-term QPUs.
