Rydberg atomic quantum receivers (RAQRs) have emerged as highly sensitive receivers for future communication and sensing systems. However, conventional RAQRs are primarily effective for single-carrier and narrowband reception, typically with an operational bandwidth of only a few hundred kilohertz. To enable the reception of multi-carrier signals with larger bandwidth, we propose a multi-carrier Rydberg atomic quantum receiver (MC-RAQR) architecture based on a five-level quantum system model. We analyze the amplitude and phase of the output laser in MC-RAQR and extract the baseband electrical signal for signal processing. Furthermore, we quantify the performance of MC-RAQR in multi-carrier communication and sensing by studying the channel capacity and distance estimation, respectively. Numerical results show that the MC-RAQR is capable of achieving a bandwidth of
7.2 MHz, which is an order of magnitude larger than conventional RAQRs. Besides, compared to conventional receivers, MC-RAQR can improve the capacity and distance estimation by
18-fold and
103-fold, respectively. This validates the superiority of MC-RAQR in receiving multi-carrier signal, and demonstrates its compatibility in detecting waveforms such as orthogonal frequency‐division multiplexing.
