ABSTRACT: Quantum technology is a promising future technology where unique quantum characteristics are taken advantage of to develop faster computation, securer communication, and high-precision sensing than their classical (non-quantum) counterparts. Quantum tomography is a fundamental task for developing powerful quantum technology and quantum autoencoders are promising for quantum data compression. In this talk, we will first present several results on optimization, adaptivity, computational complexity and error analysis in quantum state tomography, quantum detector tomography, quantum Hamiltonian identification, and quantum process tomography. Then we will present a couple of results on the compression rate of quantum autoencoders and how to use mixed reference states and learning control to optimize the performance of quantum autoencoders.
