Million FPS 100 100 pixel Optical Modulators and Detectors for Fast Atom-Array Quantum Computing
Abstract
While atom array technology is rapidly progressing, there is a substantial bottleneck on the horizon, presented by limitations in fast, parallel atom movement, control and readout. For atom movement and control, the ~kHz framerate of SLMs necessitates crossed AODs rapid beam control, preventing full capitalization on the arbitrary connectivity possible with atom arrays. For atom readout, inefficient light collection and slow cameras limit readout speeds to ~1 ms.Here we propose to develop two technologies: (i) a frequencymultiplexed multi-channel optical modulator that leverages a single fiber EOM to control a 100 × 100 pixel display at 1Mfps; (ii) asingle-photon sensitive, 1Mfps camera. In each case, we propose two different approaches to realizing the technology. For the 100 ×100 modulator we will explore (a) arrays of frequency-non-degenerate optical cavities and (b) crossing two of a new type of lens VIPA, with higher frequency resolution. For the 100 × 100 camera we will explore (a) time-domain multiplexing onto a single SPCM usingan array of buffer cavities; and (b) patterned sub-frame illumination of an EMCCD, read out during frame-transfer.Taken together, these tools provide a 100× ~ 1000× bandwidth increase in our ability to manipulate and detect the states of large arrays of atoms, vastly extending the envelope of what is possible for current generation quantum computers. We also anticipate that such high-bandwidth, parallel optics tools will find applications far beyond quantum information science, from LIDAR to bio-sensing. The new VIPA technology also promises to be impactful anywhere high-resolution spectroscopy is important.#Approved for public release#
