Gaps in the coherence spectrum of diode lasers have been known to hinder research. Anselm Deninger and Thomas Renner look at how these gaps are being filled and the applications that are benefiting ...

Researchers have uncovered an interface layer that may affect the performance of certain superconducting qubits.

Two milliseconds – or two thousandths of a second – is an extraordinarily long time in the world of quantum computing. On these timescales the blink of an eye – at one 10th of a second – is like an ...
