The Quantum Realm will be very important to the future of the Ant-Man and the Wasp that really showed its long-term potential.
Although there's still only a limited amount of time spent in the Quantum Realm, the sequel continued to share new pieces of information on what it can do. An energy blast from a quantum experiment gave Ghost her powers and Janet van Dyne's time spent in the dimension also gave her new (and largely unexplored) abilities. However, it also included a quick showing of a city within the realm. Despite this new information, it's still a corner of the MCU that is still relatively unexplored.

The Quantum Realm could become even more important to the MCU very soon too, thanks to has been linked to the Quantum Realm for quite some time, including prominent theories that the realm is partially responsible for giving Carol Danvers her super powers. So, when Screen Rant had the opportunity to speak to Kevin Feige at the Captain Marvel junket, we asked him about the future of this dimension.
Screen Rant: It seems that the Quantum Realm is positioned to be as potentially important as the Infinity Stones were in the first 10 years. How important will this concept be?
I think really important. I think it's one of the fun things about the comics that allow you to explore entirely new terrains. And we've hinted at it now in numerous films and it's untapped, primarily untapped potential.
The importance of the Quantum Realm may not stop with Captain Marvel either, as it appears that possible time travel abilities (which, again, could be tied to the Quantum Realm), so she could help make this possible too.
Beyond 2019 though, the Quantum Realm could continue to be used in major ways. Feige pay even more attention to the mysterious dimension. However the Quantum Realm is explored in greater detail, it could be the cornerstone of the MCU for years to come.
