The superconducting diode effect has the potential to advance the design of non-dissipative circuit components yet there are many practical aspects to overcome before reaching the application stage. Here, the authors investigate the non-reciprocal current-voltage relationship in gate-controlled metallic nanowires, demonstrating the realisation of the superconducting diode effect without the need to break time-reversal symmetry using an applied magnetic field.
