Quantum computers have been around for about forty years, but they are currently feasible to researchers and students. For example, IBM's Quantum Computing Technology ( https://www.ibm.com/quantum ), and MicroSoft's Azure Quantum Service ( https://quantum.microsoft.com/ ), provide access to them.
However, the easiest way to learn the new languages is by using simulators, and the aforementioned companies offer courses and training such as IBM's Qiskit ( https://www.ibm.com/quantum/qiskit ), and Azure's Katas ( https://quantum.microsoft.com/en-us/tools/quantum-katas ) for people interested in learning this different approach to computer programming.
Quantum programming languages are a new challenge; and the main reason to get involved should be the application, of course. Example: vehicle routing.
About this application it is recommended to read these papers:
- Quantum Computing in Intelligent transportation Systems: A Survey ( https://arxiv.org/html/2406.00862v2 )
- Quantum Neural Networks for a Supply Chain Logistics Application ( https://arxiv.org/abs/2212.00576 )
