Tunable Laser System and Low-Temperature Magneto-Optical Microscope for Integrating Trapped Ions with Optical Memory
Abstract
We propose to acquire equipment to develop optical interconnects for trapped ionquantum information processors that will significantly improve scaling of quantumcomputers and networks. We will use the proposed equipment to pursue a novel methodto store light on-a-chip, achieve long optical delays in a small device footprint, and enablehybrid interactions between atomic and solid-state quantum memories. We request twopieces of capital equipment. The first is a pulsed laser excitation system. We will use thissystem to excite optically active trapped ion quantum memories and generate shortsingle-photon pulses. The photon pulses will be entangled with the ion quantum memoryand serve as carriers of quantum information. The second piece of equipment is a dilutionrefrigerator system with an optical axis and high-field magnet. We will use this systemto study rare-earth ion quantum memories coupled to integrated photonic structures.The rare-earth ions will store photons generated by trapped ions and will enable opticaldelays in the microsecond range. Such delays are unattainable using conventional onchipdelay lines. We will use these delays to apply phases, perform time-divisionmultiplexing, and store photons in an integrated photonic circuit. These functionalitieswill enable us to mediate long-distance interactions between ion traps in order to developcomplex quantum processors and networks. We will also explore hybrid interactionsbetween atomic and solid-state quantum memories to achieve new network architecturesthat exploit the relative advantages of both systems. The proposed equipment willsupport a number of DoD funded projects including an AFOSR funded MURI on“Scalable certification of quantum computing devices and networks”, an AFOSR fundedgrant on “Non-Local Quantum Interactions Using Trapped Ions and IntegratedPhotonics”, and the Center for Distributed Quantum Information funded by ARL.
