Slowing down an interstellar spacecraft at Alpha Centauri

While one of the most important challenges for future interstellar travel is to how send a probe to another stellar system relatively quickly, another issue that needs to be resolved is how to successfully slow down such a spacecraft once it gets there. Recently, two German researchers have proposed a solution addressing this problem, presenting a method that could flawlessly decelerate an interstellar craft sent to the neighboring system Alpha Centauri.
