Abstract summary: We show that variational scarring in two-dimensional quantum dots remains robust even in an open system. Controlled perturbations enable modulation of electronic transmission via scarred states. These findings provide insights into the role of scarring in mesoscopic transport and open pathways for experimental realization in quantum devices.

Abstract: Quantum scars have recently been directly visualized in graphene quantum dots (Nature 635, 841 (2024)), revealing their resilience and influence on electron dynamics in mesoscopic systems. Here, we examine variational scarring in two-dimensional quantum dots and demonstrate that these states remain robust even in an open system. We show that controlled perturbations enable modulation of electronic transmission via scarred states, presenting a viable approach to tuning quantum transport. These findings provide insights into the role of scarring in mesoscopic transport and open pathways for experimental realization in quantum devices.

Subdiffusion via Disordered Quantum Walks [52.77024349608834]
We experimentally prove the feasibility of disordered quantum walks to realize a quantum simulator that is able to model general subdiffusive phenomena. Our experiment simulates such phenomena by means of a finely controlled insertion of various levels of disorder during the evolution of the walker. This allows us to explore the full range of subdiffusive behaviors, ranging from anomalous Anderson localization to normal diffusion.

Quantum Zeno effect appears in stages [64.41511459132334]
In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates. We show that the onset of the Zeno regime is marked by a $textitcascade of transitions$ in the system dynamics as the measurement strength is increased.
