It is estimated that a journey from Earth to Mars takes between 150-300 days depending on the speed of the launch and the alignment of Earth and Mars.
Now, NASA says a new form of laser-based propulsion could get us to Mars faster than has ever been possible.

It isn't new, the science is many decades old. And they are using interstellar velocities without factoring deceleration and acceleration times. If you fly towards Mars at .25 of the speed of light, you have to slow down too. This is real interstellar technology but it has no applications for interplanetary travel as discussed here. Light sails can work locally to of course, but they are not going to be nearly that fast.
