Qubits are — analogous to bits in conventional computing — the smallest unit of quantum signals. (sciencedaily.com)
Therefore, we are able to exactly separate the detrimental effect of the noise from the weaker quantum signal through precise coupling to the waveguide.» (sciencedaily.com)
In recent years it has become clear that none of these quantum building blocks is able to meet all the requirements such as receiving and storing quantum signals, processing and transmitting them. (sciencedaily.com)
