Revisiting the quantum open system dynamics of central spin model

2021 · arXiv (Cornell University)

In this article we revisit the theory of open quantum systems from the perspective of fermionic baths. Specifically, we concentrate on the dynamics of a central spin half particle interacting with a spin bath. We …

Using Quantum Switches to Mitigate Noise in Grover's Search Algorithm

2024 · arXiv (Cornell University)

Grover's quantum search algorithm promises a quadratic speedup for unstructured search over its classical counterpart. But this advantage is affected by noise acting on the search space. Here, we show that a quantum switch can …
