  1. Nov 27, 2023We propose a protocol for the amplified detection of low-intensity terahertz radiation using Rydberg tweezer arrays. The protocol offers single photon sensitivity together with a low dark count rate. It is split into two phases: during a sensing phase, it harnesses strong terahertz-range transitions between highly excited Rydberg states to capture individual terahertz photons. During an ...
  2. photon into a detectable avalanche of Rydberg atoms. Dynamical THz detection protocol — The THz detection protocol is depicted schematically in Fig. 1b,c. It consists of four steps: preparation of the initial state, the sensing mode, the amplification mode and, finally, the measurement. In the first step, the tweezer array is

    In this work we propose and theoretically investigate a protocol which allows for the amplified detection of THz radiation at the single THz photon level utilizing additionally the strong state-dependent inter-atomic interactions between Rydberg atoms. These interactions have already been used for enhanced metrological protocols [9, 10, 11, 12].Our detector is based on a Rydberg tweezer array ...

    arrays of 87Rb atoms trapped in optical tweezers. The atoms are arranged in groups of equilateral triangles [Fig. 1(a)]. We encode a qubit using two Rydberg states j↑i¼j60S1=2;m J ¼1=2i and j↓i¼j60P1=2;m J ¼ −1=2i. The atoms are coupled via dipolar interactions, described by the XY Hamiltonian: H XY ¼ J 2 X i<j a3 r3 ij ðσx iσ x ...
