Proof of the hiding conjecture for Gaussian boson sampling with an arbitrary number of squeezed input modes
Laura Shou, Alexey V. Gorshkov, Victor Galitski +1
Gaussian boson sampling (GBS) is a sampling task proposed to demonstrate quantum advantage. We consider Gaussian boson sampling on optical modes, with equally squeezed inpu…
Fock-state preparation based on amplitude amplification in cavity QED
Sharoon Austin, Zhi-Yuan Wei, Kartik Srinivasan +1
The paper introduces amplitude‑amplification techniques for coherent control in cavity QED, enabling faster single‑photon generation and efficient preparation of Fock and NOON stat…
Differentially private quantum sensor networks
Daniel J. Spencer, Kaiyan Shi, Emil T. Khabiboulline +2
Quantum sensing is a promising technology capable of demonstrating clear advantage over comparable classical techniques for precise measurement. One application of quantum sensing…
An efficient Pauli decomposition algorithm for structured matrices
Daniel J. Spencer, Kishor Bharti, Alexey V. Gorshkov
Decomposing classical matrices into linear combinations of Pauli strings is a major bottleneck for end-to-end implementations of near-term quantum algorithms. In this work, we cons…
Multiparameter function estimation for general Hamiltonians
Erfan Abbasgholinejad, Sean R. Muleady, Jacob Bringewatt +2
Estimation of physical parameters encoded in a Hamiltonian is a central task in quantum sensing and learning. While the ultimate precision limit for estimating a single parameter c…
Precision Limits of Multiparameter Markovian-Noise Metrology
Anthony J. Brady, Yu-Xin Wang, Luis Pedro GarcÃa-Pintos +1
Measuring stochastic signals ("noise metrology") constitutes a central task in quantum sensing and the characterization of open quantum systems. Here we establish ultimate precisio…
