Researchers Compute Jones Polynomial Using Majorana Zero Modes Introduction to Jones Polynomials and Topological Invariants A research team has successfully calculated the Jones polynomial ex perimentally using quantum simulations of braided Majorana zero modes. By simulating the braiding o perations of Majorana fermions, they determined the Jones  polynomials for various links. Their findings were  published in Physical Review Letters . Im portance of Jones Polynomials in To pology Link and Knot Invariants Invariants of links or knots, like the Jones  polynomials, are essential tools for assessing the to pological equivalence of knots. Their determination is of significant interest due to a p plications s panning fields like DNA biology and condensed matter  physics . Com putational Challenges and the Promise of Quantum Simulations A p proximating the Jones  polynomials is a com putationally challenging task, classified as #P-hard, with classical algorithms d...

Unlocking Quantum Simulations: Scientists Develop Techniques for Estimating Hamiltonian Parameters in Superconducting Quantum Simulators Introduction Scientists from Freie University Berlin, University of Maryland, NIST, Google AI, and Abu Dhabi aimed to estimate the free Hamiltonian parameters of bosonic excitations in su perconducting quantum simulators. Their  protocols, shared in an arXiv  pre print, could enable highly  precise quantum simulations that sur pass classical com puting. The Call from Google AI Jens Eisert, the  pa per's lead author, told "I was attending a conference in Brazil when i got a call from colleagues at the Google AI team." Challenges in Calibrating Quantum Chi ps "While working to calibrate their Sycamore su perconducting quantum chi p with Hamiltonian learning methods, they encountered substantial difficulties and called for hel p. With my background in analog quantum simulation and systems identification, I found their request  pa...
