Unfortunately they plan on using this technology for quantum computers. That doesn’t mean that someone else might not pick up this technology and make them real, although I can already hear the cries: “Why do you need a lightsaber?” “Ban lightsabers today!” “No lightsaber blades over 3 inches.” Read the whole article here:
