Ultra-Dense Quantum Communication Using Integrated Photonic Architecture: Second Quarterly Report
Abstract
We report on progress towards the goal of establishing a fundamental information-theoretic understanding of quantum secure communication and devising practical and scalable implementations of quantum key distribution protocols in a photonic integrated chip platform. The goal of this program is to experimentally and theoretically investigate the fundamental information capacity of optical communications and to develop revolutionary technology that will enable unprecedented information content, in excess of 10 bits per photon (bpp), while guaranteeing absolute security at high communication rates of 1 Gbps or more. The following sections detail the progress towards theoretical and experimental goals. Three lines of work have been pursued during this reporting period. First, the theory of secrecy capacity for multiple-input, multiple-output, multiple-eavesdropper (MIMOME) classical channels with additive Gaussian noise is being extended to MIMOME bosonic channels. The second theory area we are working is the quantum bootstrap protocol for secure communication. The last theory area we have been addressing is to determine and compare the cross-talk characteristics of multiple-spatial mode systems that use Hermite-Gaussian (HG) or Laguerre-Gaussian (LG) field patterns when propagation is through atmospheric turbulence.
