Project Description
Experiments at Purdue have recently demonstrated frequency bin entanglement with on-chip optical microresonator photon pair sources, proving entanglement in two and three frequency dimensions. These biphoton frequency combs already show up to 40 correlated signal and idler frequencies, suggesting potential for entanglement over much higher dimensionality (of interest, e.g., due to potential for higher information capacity per particle). Purdue has also collaborated with Oak Ridge National Lab on realization of quantum gates for frequency bin entangled photons. One-photon gates have been demonstrated in two and three frequency dimensions (the first high dimensional gate for frequency encoded photons), and two photon gates are under investigation. The proposed project seeks to advance the science and technology of the new subfield of frequency-encoded photons for quantum information processing. Topics of interest include but are not limited to: generation of frequency-bin entanglement, hyper entanglement in frequency, time, and/or space, and multi-photon entangled states; protocols and algorithms to certify and exploit frequency bin entanglement in higher dimensions; applications to quantum communications and networking, such as high dimensional quantum teleportation; and application of high-dimensional entanglement to quantum simulation. Opportunities to collaborate on photonic integration supporting this research are also anticipated.
