For the first time, Australian engineers have demonstrated that they can write and manipulate the quantum version of computer code on a silicon microchip.
This was done by entangling two quantum bits with the highest accuracy ever recorded, and it means that we can now start to program for the super-powerful quantum computers of the future.
Engineers code regular computers using traditional bits, which can be in one of two states: 1 or 0. Together, two bits create code words that can be used to program complex instructions. But in quantum computing language there’s also the possibility for bits to be in superposition, which means they can be 1 and 0 at the same time. This opens up a vastly more powerful programming language, but until now researchers haven’t been able to figure out how to write it.
