Qubits, the key building blocks at the heart of every quantum computer, are extremely sensitive to interference and need to be shielded from unwanted signals, for example by using so-called nonreciprocal devices. But until now these devices were huge and produced unwanted magnetic fields themselves. Now, scientists have developed a new nonreciprocal device that is only a tenth of a millimeter wide, and -- maybe even more importantly -- is not magnetic.
