The Quantum Realm is highly-expected to factor in the story of Avengers: Endgame, which will help the Avengers defeat Thanos once and for all, and there are already plenty of clues in the movie's marketing so far.
Introduced in 2015's Ant-Man after Scott Lang (Paul Rudd) went subatomic, the Quantum Realm is defined as "a reality where all concepts of time and space become irrelevant as you shrink for all eternity," as explained by Dr. Hank Pym (Michael Douglas). It made a brief appearance in 2017's Doctor Strange when the Ancient One sent Stephen Strange's consciousness through several dimensions and realities. At this point, it was also established that it can be accessed through the sorcerers' sling ring. Last year, we learned more about it in Ant-Man & The Wasp, which offered the best look at the largely unexplored realm when Hank traveled through the Quantum Tunnel to save the original Wasp, Janet van Dyne, who had been trapped there for decades.
The Quantum Realm's involvement in Avengers: Endgame is linked with the popular theory that the Avengers will travel back in time in an effort to restore peace and order in the universe after Thanos' snap that left half of life in the universe dusted in Avengers: Infinity War. Here are all the clues suggesting that it will be pivotal in the heroes' upcoming mission.

The Avengers' Wrist Devices
The mysterious wrist devices were first spotted on the leaked Avengers: Endgame set photos from the end of principal photography in January 2018. It was worn by a noticeably older Iron Man, Captain America (wearing his original suit), Ant-Man, and the Hulk in the middle of the wrecked-metropolitan area, which is most likely a recreation of the Battle of New York from 2012's The Avengers. The paraphernalia and its uses quickly roused questions from fans. In the images, the heroes are wearing the device at the back of their left wrists, and based on its green face, more details are expected to be added during post-production.
The same wrist piece was featured in a couple pieces of Endgame's tie-in merchandise, such as a brand new Funko Pop for Iron Man and a promo artwork for a toy set with Rocket wearing the said accessory. However, it has yet to be explicitly featured in any previews for the film - until Avengers: Endgame's second trailer. During a split-second shot, Hawkeye can be seen wearing the same device when he and Black Widow are aboard what appears to be the Benatar. Based on Nat's grown hair, time has passed since the events of Infinity War at this point.
So how does the device link up to the Quantum Realm? It goes back to theories about how the alternate dimension will allow the heroes to travel back in time and this accessory might help make it happen. It could serve as a guiding equipment for the Avengers as they travel through time and space, ensuring that they will land on the specific setting they want to revisit. Another possibility is that it enables them to navigate previous events without effectively rewriting history and rendering everything that the MCU has built up to this point insignificant.
Ant-Man's Quantum Tunnel Van
During the post-credit scene of Ant-Man & the Wasp, Hank, Janet, Hope, and Scott are on a rooftop with Luis' van, which they've installed a miniature version of the Quantum Tunnel into. Scott successfully dove into the alternate world to gather Quantum Healing Particles. Unfortunately, Thanos had executed his snap, which killed the Pyms, right when Ant-Man was going to exit the Quantum Realm. This left Scott trapped and clueless inside the Quantum Realm. Official footage confirms his survival, and in the first Avengers: Endgame trailer, the same van can be spotted with Scott outside the Avengers HQ as he asks the heroes to let him in.
It's still unclear how Scott is able to escape the Quantum Realm, but the general thinking is that he returned to a post-apocalyptic world not knowing what happened. With the Pyms gone, he has no one else to get answers from, so he makes his way from San Francisco to upstate New York, where the new Avengers base is, using the van as his transport. Furthermore, Avengers: Endgame's Super Bowl spot revealed that he will join the remaining heroes left alive, effectively providing the Avengers with access to the Quantum Realm. This makes it easier for them to dive into the subatomic dimension once they've discovered its capabilities that might allow them to travel back in time.
