The quantum drive is an engine based on the manipulation of the quantum medium, which allow ships to cross the distances between the bodies of a star system. Currently, ships in quantum will travel at approximately 0.2c, or 20% of the speed of light  .
On May 3, 2075, the first self-sustaining quantum drive engine was completed by Dr. Scott Childress along with a team from RSI. It was capable of space travel at 1% of the speed of light. Overnight, the space travel industry was born and spaceflight for civilians became possible.
