The idea of quantum computers plotting the perfect route for delivery trucks sounds like something out of a sci-fi logistics simulator. And to be fair, both FedEx and DHL have been investing real resources into making it happen. But the claim that these companies are already saving 12% to 20% on fuel through quantum routing deserves a closer look, because the actual data tells a more complicated story.

What the numbers actually show

FedEx has been exploring quantum approaches for warehouse layout optimization since the early 2020s. The company has reported improved operational layouts from these experiments. But here’s what’s notable: none of the published results from FedEx’s quantum initiatives cite specific fuel-savings percentages.

DHL’s quantum story is a bit more detailed. The company ran a specific pilot project with Groovenauts and Honeywell that produced an estimated 60% reduction in carbon emissions. That’s a genuinely impressive number, but carbon emissions and fuel savings are not the same metric. A fleet could reduce emissions through electrification, alternative fuels, or operational changes that don’t necessarily translate into a 12-20% reduction in fuel costs.

Meanwhile, FedEx’s non-quantum dynamic routing methods, the kind of advanced algorithmic optimization that runs on classical computers, reportedly yield fuel and labor cost reductions of 10-15%. As of mid-2026, no large-scale deployments of quantum logistics routing have confirmed fuel savings in the 12-20% range. The technology remains largely in pilot and exploratory stages at both companies.

The crypto angle that isn’t there

For readers wondering whether blockchain or crypto tokens play any role in these quantum logistics initiatives: they don’t. None of the reviewed projects from either FedEx or DHL involve cryptocurrency protocols, tokenized incentive structures, or blockchain-based supply chain integrations tied to their quantum computing work.

Traditional optimization methods are still delivering the most reliable cost savings in the 10-15% range. Investors and stakeholders should treat quantum logistics as a long-duration bet. The underlying science is sound, and the potential is real. But anyone pricing in 12-20% fuel savings as a current achievement rather than an aspirational target may be getting ahead of the actual data by a meaningful margin.
