Quantum parameter estimation with the Landau-Zener transition
Jing Yang, Shengshi Pang, Andrew N. Jordan
We investigate the fundamental limits in precision allowed by quantum mechanics from Landau-Zener transitions, concerning Hamiltonian parameters. While the Landau-Zener transition…
Optimal adaptive control for quantum metrology with time-dependent Hamiltonians
Shengshi Pang, Andrew N. Jordan
Quantum metrology has been studied for a wide range of systems with time-independent Hamiltonians. For systems with time-dependent Hamiltonians, however, due to the complexity of d…
Protecting weak measurements against systematic errors
Shengshi Pang, Jose Raul Gonzalez Alonso, Todd A. Brun +1
In this work, we consider the systematic error of quantum metrology by weak measurements under decoherence. We derive the systematic error of maximum likelihood estimation in gener…
Precision optical displacement measurements using biphotons
Kevin Lyons, Shengshi Pang, Paul G. Kwiat +1
We propose and examine the use of biphoton pairs, such as those created in parametric down conversion or four-wave mixing, to enhance the precision and the resolution of measuring…
