Quantum computing is expected to revolutionize electronics over the course of the next few decades, but a number of outstanding issues still remain. One such problem is that "qubits," the basic building blocks of quantum information, are very fragile and can be easily destroyed when sent on a fiber optics cable, due to the surrounding noise. Working on this issue, a team from Stockholm's KHT University, led by Magnus Rådmark, has developed a new method for combining six photons to obtain a robust qubit that is resistant to noise and is, therefore, able to travel long distances without interference.
