Semidefinite Programming applied to Quantum Channel Learning

A new paper details the application of Semidefinite Programming (SDP) to the problem of reconstructing quantum channels from classical data. The research, led by Vladislav Malyshkin, highlights that SDP can efficiently solve fidelity optimization problems when the total fidelity is a ratio of quadratic forms. The study found that a relatively small Kraus rank is typically sufficient to describe experimental data, suggesting that simpler quantum channels can often model observed phenomena. The paper also explores applying this theory to reconstruct projective operators and discusses a classical computational model for quantum channel transformation. AI

    Semidefinite Programming for Quantum Channel Learning

    arXiv:2601.12502v2 Announce Type: replace Abstract: The problem of reconstructing a quantum channel from a sample of classical data is considered. When the total fidelity can be represented as a ratio of two quadratic forms (e.g., in the case of mapping a mixed state to a pure st…
