Research Topic Description, including Problem Statement:

  • Superconducting circuitry is a leading approach in quantum information science due to ease of fabrication, fast processing power and simple coupling schemes. However, these devices operate at microwave frequencies and thus must reside at milli-kelvin temperatures inside a dilution refrigerator in order to preserve their quantum information. However, quantum information is best sent over long distances using optical photons due to their immunity to thermal fluctuations at room temperature. Hence, in order enable long distance communication between remote microwave quantum nodes, high efficiency quantum state transduction from microwave to optical wavelengths is required with high rep-rates and low added noise. This capability is particularly relevant for future quantum networks which could have applications for remote quantum sensing, secure communications and distributed quantum computing.
  • The goal of this topic is to work towards the transfer of quantum information from a microwave photon into an optical photon and visa-versa with high fidelity. The ultimate objective is to entangle two remote superconducting qubits via optical photons.


Example Approaches:

  • There are many approaches currently being explored for microwave-to-optical quantum state transduction purposes. Example approaches include:
    • Electro-optics: Traditionally microwave signals are converted into optical signals using electro-optics. However this process is very inefficient and thus not suitable for quantum applications. To overcome these limitations researchers are working towards resonant electro-optic devices coupled with optical pumping schemes. (Ref: Tsang, PRA 81; 063837, 2010)
    • Opto-mechanical: Mechanical devices can couple to both microwave and optical resonant cavities and can serve as a low-noise transduction element between these two systems. (Nature Phys 10, 321, 2014)
    • Rare-earth crystal: Rare-earth doped crystals can have both narrow linewidth microwave and optical transitions. When coupled to a microwave and optical cavity, efficient conversion could be possible (PRL 113, 203601 (2014))
    • Neutral atoms: A single atom in a Rydberg state has a large enough dipole moment to couple to a superconducting resonator. This state can then be coupled to an optical transition via laser control and thus could be used for quantum state transduction (PRA, 96, 013833, (2017))


Relevance to the Intelligence Community:

  • Long distance quantum state transfer is an enabling technology for future quantum networks. Such networks could have many potential applications relevant to the IC community including remote quantum sensing, secure quantum communications and distributed quantum computing.
