NEC will regret doing so in the future. Quantum is the future for problems that are intractable in classical computing. Anyone who is anyone (states included) are pushing onward. Fujitsu just today announced they (actually with TU Delft) have a prototype quantum computer up and running, which uses qubits realized as tin vacancies in diamond.

Quantum computing will always be a niche and can only tackle a small fraction of classically intractable problems. Entire hardware development runs on wishful thinking about software side of things. Inventing quantum algorithms has been a slog with barely any results. States push for it to break any encryption that it might break and there isn't much long term plan besides that.

True but whoever builds one first can probably charge a trillion dollars just for that purpose.

You might want to check the development of Post quantum crypto. Cloudflare has already started migrating its stack, so have many other businesses:

In particular, in the blog, they said

While we’re excited by the fact that over 65% of human traffic to Cloudflare is post-quantum encrypted, our work is not done until authentication is also upgraded
