Challenges in patenting quantum tech

Quantum mechanics is a theory of sub-atomic particles including counter-intuitive concepts such potons and electrons being both waves and particles. Quantum mechanics was discovered between the end of the 19th and start of the 20th centuries and was touted as world-changing due to the enormous technological implications. However, owing to the dense theory and non-intuitive concepts, it is often forgotten how it has changed the landscape of technology.
