Optical co mputing, where signals are sent via light rather than electricity, pro mises to be f aster than co nventio nal chips, if lasers can be mass pro duced in miniature (silico n laser experiments sho w pro mise). Others are experimenting by craf ting co mputing co mpo nents using bio lo gical material (think a DNAbased sto rage device). One yet-to -be-pro ven techno lo gy that co uld blo w the lid o f f what’s po ssible to day is quantum co mputing. Co nventio nal co mputing sto res data as a co mbinatio n o f bits, where a bit is either a o ne o r a zero . Quantum co mputers, leveraging principles o f quantum physics, emplo y qubits that can be bo th o ne and zero at the same time. Add a bit to a co nventio nal co mputer’s memo ry and yo u do uble its capacity. Add a bit to a quantum co mputer and its capacity increases expo nentially.

Quantum co mputing might also accurately predict the weather mo nths in advance o r o f f er unbreakable co mputer security. Ever have tro uble placing a name with a f ace?
