Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser pulses, the new logic gates are a million times faster than those in existing computers,…
In few years our power super gaming PC seems a Abacus to us. The first personal Quandum computer is in the market since last year, for $5000 (2 Qbits, not really usefull yet), but remeber the developement since 15-20 years with the current exponential advances. Current cheap smartphones are high end PC 15 years ago.
There were good reasons to think that silicon based electronics will have exponential advances (basically scaling down components makes them exponentially faster by default). Do we have similar physical properties of quantum computing tech? Perhaps silicon was special and now we are at the end of it with nothing that has this exponential property anymore to replace it.
Yes, scaling down silicon based electronics gaining in speed, but only until certain limits which have silicon to scaling down the components, currently un atomic scale. Because of this are investigated other materials, like syntetic diamonds, which soports much more heat and with this a major processing speed. Quantum computing ofrfers much more speed, because it isn’t limited to 1 OR 0, it can process simultaneous 1 AND O AND everything in between, until now the difficult is that it need very low temperatures and the lack of stability with minimum interferences. But technology is advancing and cooling by magnetic means makes it possible to dispense with nitrogen/helium cooling and allows its application in desktop PCs, although at the moment only with three Qbits, suitable for both research and education use for complex calculations. Well, with the first PCs the same thing happened.
