We present a method to control the detection events in quantum key distribution systems that use gated single-photon detectors. We employ bright pulses as faked states, timed to arrive at the avalanche photodiodes outside the activation time. The attack can remain unnoticed, since the faked states do not increase the error rate per se. This allows for an intercept–resend attack, where an eavesdropper transfers her detection events to the legitimate receiver without causing any errors.

The electronic chips of the future might not be made of silicon or even graphene but of a material called molybdenite (MoS2). EU-funded research presented in the journal Nature Nanotechnology demonstrates that molybdenite is a highly effective semi-conductor that could be used to make transistors both smaller and more energy efficient.
