Cavity Tweezer Arrays for Quantum Networking
Abstract
Light collection plays a crucial role in determining speed/fidelity of state-detection and readout inquantum information processors and information transmission efficiency in quantum communica-tion nodes. Atom array experiments which rely on microscope objectives for light collection are limited in their efficiency by the finite solid angle subtended by the objective lens. Cavities enhance the effective solid angle subtended by the optics by a factor of the finesse (how many round-trips the light makes) and thus can provide a collection efficiency nearing 100%. In the Simon lab we have recently developed a new type of Fabry-Perot resonator where high cooperativity is achieved via a wavelength-scale resonator waist (high NA) and a low optical finesse rather than the standard approach of a larger resonator waist (low NA) and a high finesse. This new resonator architecture drastically reduces the technical overhead associated with efficient light collection from quantum emitters and makes possible with only a single in-vacuum lens integration of arrays of optical cavities with atom arrays for quantum information science and manybody physics. In this grant we propose to begin capitalizing on the promise of this break-through resonator technology to build a first-of-its-kind atom-array quantum repeater. In addition to realizing for the first time the resonator array technology we will demonstrate theability to perform multiplexed entanglement distribution initially without and then with heraldingand quantum memories (to improve entanglement rates). We will conclude with a demonstrationof deterministic Rydberg-mediated entanglement swapping removing SPCM efficiency and post-selection as rate limiters. Although we do not propose to explore quantum-error-correction of anysort in this program the architecture we develop will be ideally positioned to tackle QEC in gen. 2& 3 repeaters as the next step. By submission of the project abstract, the applicant confirms that the abstract is releasable to the public.
