High-T_c superconducting nanowire detectors can detect single photons of telecom wavelengths at a temperature of 25 K and may enable applications in quantum sensing and quantum information processing.

Theoretical research into quantum information engines that surpass the classical Carnot limit has exploded these past 10 years, but experiments so far have almost exclusively been the realm of the optics community. To help advance the field, and to develop solutions that might help our energy-dependent global society navigate the planetary crises, it’s high time that physicists working on atom-level electronics join the game.

‘Squeezing’ of light can be used to alter the distribution of quantum noise to benefit quantum sensing and other applications. An improved design for a microwave photon squeezer provides high performance over a large bandwidth.

Measurements of charge pumping in a quantum anomalous Hall device demonstrate that quantized Hall conductance does not require an edge to transport current, paving the way for the realization of other exotic electronic behaviour.

A BP/CdS heterostructure-based artificial photonic synapse with an ultra-low power consumption is proposed, presenting great potential in high-performance neuromorphic vision systems.
