Moving quantum sensors
Evan Zhang, Erfan Abbasgholinejad, Yu-Xin Wang +6
We investigate whether controlled motion of a quantum sensor offers a metrological advantage in a field-detection task. We consider a localized field of known strength occupyin…
Bosonic unstructured search: quantum enhancement without entanglement
Yu-Xin Wang, Erfan Abbasgholinejad, Supratik Sarkar +4
We consider unstructured search using multimode bosonic quantum systems under energy constraints. The task is to locate an unknown marked mode among possibilities using arbitra…
Anticoncentration and entanglement in Gaussian boson sampling
Laura Shou, Adam Ehrenberg, Yu-Xin Wang +2
Anticoncentration and entanglement are two properties used to study classical hardness or easiness of Gaussian boson sampling in varying regimes. In this paper, we consider three d…
Fault-Tolerant Heisenberg-Limited Quantum Sensing
