Acquisition of a Dilution Refrigerator for the Investigation of Quantum Emitters
Abstract
We are in the midst of the Òsecond quantum revolutionÓ. Applications of quantum science in the form of enhanced computing algorithms, unbreakable communication protocols, and ultrasensitive detection strategies are presently driving a broad scientific and engineering effort that promises to reframe the limits of modern information processing. The ÒphotonÓ, the quantum of light, has become the most attractive carrier of classical and quantum information and hence there is an ongoing, widespread search to identify and exploit single photon emitters in solid-state hosts to generate and store quantum information. To keep CCNYÕs quantum research enterprise on par with current trends, we propose the acquisition of a closed-cycle dilution refrigerator, which we will apply to the investigation of quantum emitters in solid state hosts, with emphasis on the interplay between spin, charge, and photon emission properties. Specific research areas include: ¥ the discovery and characterization of novel paramagnetic, magneto-optical color centers with emission in the infrared for integration into the telecom band; ¥ the detection and manipulation of excited donor states in neutral paramagnetic defects with emphasis on their application as a spin-photon interface; ¥ the generation and control of exciton-polariton Moire patterns for quantum simulation; ¥ the study of spin-polarized carrier injection via bound-exciton-mediated charge capture; ¥ the investigation of superconductor/dichalcogenides structures as a source of correlated photons. The Janis dilution refrigerator we propose has a base temperature of 10 mK; the anticipated operating temperature in the presence of optical illumination (fed into the sample via optical fibers) is approximately 100 mK. The work space in the main chamber is large, thus allowing us to place the position stages required for optical microscopy. It also features a closed-cycle cooling system with high vibrational stability, which makes it compatible with optical measurements. Projected Impact With recent methodological breakthroughs and the emergence of practical quantum technologies, training the most inclusive generation of quantum scientists and engineers is not only a moral obligation but also a strategic national need. Our ability to fulfill this mission, however, is becoming increasingly under pressure because not all academic institutions enjoy the same level of access to the emerging opportunities in this field. Therefore, adding to the technological and scientific outcome, the proposed instrument is expected to have a profound educational and societal impact because it will expose students and postdocs Ñ most often belonging to underserved groups Ñ to problems of current interest while facilitating their ability to interact with a wide network of collaborating labs at the forefront of quantum science. Both PIs are part of the NSF-funded CREST center at CCNY specifically aimed at mentoring and training students in material sciences and quantum technologies. This partnership not only provides a broad dissemination platform but also allows the PIs to successfully attract and recruit students from communities under-represented in the sciences.
