A Quantum Jump Marker in Star Citizen is a marker that appears on the player's HUD when they engage their quantum drive to travel faster than light to a destination. The marker will point the direction they need to travel in quantum in order to reach their selected destination.

The marker helps guide players as they perform quantum jumps between locations in the game world.
