This report <https://www.tomshardware.com/tech-industry/quantum-computing/nec-has-quietly-quit-quantum-computing-hardware-development-report-claims-company-says-it-will-continue-to-evaluate-practical-applications-and-industrialization-of-quantum-technologies> mentions that NEC has stopped developing quantum computing hardware and sacked a bunch of its quantum-computing researchers, who have moved to Fujitsu. The company is trying to deny any shutdown of quantum-computing research efforts as such. At this stage, no other companies already invested in quantum computing seem to be planning to wind down their efforts. But as the needed investment continues to climb, while any prospect of return remains distant, perhaps this will turn into a real trend.
