  • Probing quantum entanglement from magnetic-sublevels populations: beyond spin squeezing inequalities
    Jul 18 2023

    Today I review this paper:

    In this episode, we discuss a new approach to detecting quantum entanglement in many-body systems. The approach is based on Zeeman-sublevel population measurements, and it is more sensitive to entanglement than traditional methods. We explore how this approach can be used to study entanglement in spin-1 and spin-2 Bose-Einstein condensates, and we discuss the implications of the results for the development of new quantum technologies.

    To read the summary, look at our WordPress or Medium.

  • QKD parameter estimation by two-universal hashing
    Jun 27 2023

    Dimiter Ostrev proposes a new QKD protocol that uses two-universal hashing instead of random sampling to estimate the number of bit flip and phase flip errors. This protocol dramatically outperforms previous QKD protocols for small block sizes.

    Check out the original paper, or read my medium or WordPress versions of the summary.

  • Structural risk minimization for quantum linear classifiers
    Jun 27 2023

    You can read the paper here:

    https://quantum-journal.org/papers/q-2023-01-13-893/

    Or if you want to read a summary, try my wordpress or medium!

    The paper summarized here studies how to balance between training accuracy and generalization performance (also called structural risk minimization) for two prominent QML models using relationships to classical models.

  • An Improved Sample Complexity Lower Bound for (Fidelity) Quantum State Tomography
    Jun 19 2023

    https://quantumsumm.wordpress.com/2023/06/19/an-improved-sample-complexity-lower-bound-for-fidelity-quantum-state-tomography/

    https://medium.com/@quantumsumm/an-improved-sample-complexity-lower-bound-for-fidelity-quantum-state-tomography-90c1629664a8

    As this paper is so short, it is a worthwhile read for anyone and good practice for getting into the habit of reading papers. Although it is very dense (as most quantum papers are) the four pages it takes up are in no way a waste of time. It may even take less time than this podcast, but you can't drive while doing that.
