Well someone's going to have to advance quantum networking, because its underpinnings are already moving into the realm of the practical (and therefore into alliances of industry and academia).
"Realm of the practical" doesn't exactly translate to a rollout to our phones and laptops tomorrow. For instance, much of the work being done now is performed at extremely low temperatures, so we need ongoing research in materials and container construction, to make it possible for quantum networks to function at least in part in more ordinary temperatures.
So I'm not going to start out by asking "what could possibly go wrong?"
However, if one reads even a little way into articles about the Amazon-Harvard collaboration, just even to get a grip on what quantum networking may provide us as time goes on, well.. asking that question early seems like a pretty good idea.

Still, we've never been very good at predicting either what great leaps forward or what terrible mishaps may ensue from exploring "what's next?" in the course of scientific explorations and practical applications of our discoveries. So I say embrace the alliance for now, and let's hope we find more positive than negative value in creating a whole new kind of internet with capabilities we can't even imagine right now.
Unprecedented power and security, eh? Nice combo. Now can start asking about what could possibly go wrong?
Sounds cool. Hope we don't wake up the wrong half-dead cat in some rando box on an otherwise boring afternoon.

Through a three-year research alliance, enabled by Harvard’s Office of Technology Development, AWS will provide support of faculty-led and designed research projects at HQI in quantum memories, integrated photonics, and quantum materials. The principal goal of the research projects is to develop foundational methods and technologies for what eventually will become a quantum internet.
Separate philanthropic support from AWS will help Harvard train and support graduate students and postdoctoral researchers, especially with the goal of welcoming aspiring scientists and engineers from underrepresented backgrounds.
One feature [of the quantum internet] is security of information, because the shuttling of quantum states means you can detect the presence of any eavesdropper. The second is coherence, basically a way to access quantum computers — once they become ready for primetime — in completely quantum fashion. For example, this could allow a user to generate a complex quantum state, send it via quantum internet — along with the quantum algorithm — to the quantum computer, do computation, and then retrieve the quantum state that is the result of the computation. Such an end-to-end quantum system — “quantum cloud,” as I like to call it — would result in unprecedented computational power and security.

We are talking here about not just the next generation of internet, but about the internet with fundamentally new capabilities. Apart from secure communication, applications could include networked quantum computers with fundamentally new possibilities. One example is “blind” quantum computing where computation can be executed on a quantum cloud without anybody — including parties running the cloud — having a possibility to find out what is being computed, new types of distributed sensor networks, secure voting and decision-making, and more.
This is an inflection point, where a new scientific field is being born, involving the interface between quantum physics, chemistry, computer science, and device engineering. Analogies from the past include the emergence of new fields such as electrical engineering or computer science. They emerged from disciplines such as physics or mathematics and both had a profound impact on science and society.
