The Takeaway
By using highly excited 'Rydberg' atoms that are incredibly sensitive to electric fields, researchers can catch wireless signals with far greater precision than copper antennas. This quantum approach could lead to microscopic internet receivers that require almost no power and are virtually immune to traditional interference.
From the abstract
Against the backdrop of the global drive to advance the green transformation of the information and communications technology (ICT) industry and leverage technological innovation to facilitate the achievement of Net-Zero carbon goals, research into Rydberg atomic receivers (RAREs) is gaining significant interest. RAREs leverage the electron transition phenomenon for signal reception, offering significant advantages over conventional radio frequency receivers in terms of miniaturized antenna desi
