recommendations! Published in 2018 at "Nature Communications"

DOI: 10.1038/s41467-018-07090-4

Abstract: Many experimental proposals for noisy intermediate scale quantum devices involve training a parameterized quantum circuit with a classical optimization loop. Such hybrid quantum-classical algorithms are popular for applications in quantum simulation, optimization, and machine learning.… read more here.

DOI: 10.1103/physreva.111.022426

Abstract: In the search for quantum advantage with near-term quantum devices, navigating the optimization landscape is significantly hampered by the barren plateaus phenomenon. This study presents a strategy to overcome this obstacle without changing the quantum… read more here.

DOI: 10.1103/physrevlett.126.190501

Abstract: Scrambling processes, which rapidly spread entanglement through many-body quantum systems, are difficult to investigate using standard techniques, but are relevant to quantum chaos and thermalization. In this Letter, we ask if quantum machine learning (QML)… read more here.

DOI: 10.1134/s0021364025607511

Abstract: We introduce statistical models for each of the three main sources of barren plateaus: nonlocality of the observable, entanglement of the initial state, and circuit expressivity. For instance, non-local observables are modeled by random Pauli… read more here.
