Quantum-limited metrology with product states
Sergio Boixo, Animesh Datta, Steven T. Flammia +3
We study the performance of initial product states of n-body systems in generalized quantum metrology protocols that involve estimating an unknown coupling constant in a nonlinear…

Quantum discord and the power of one qubit
Animesh Datta, Anil Shaji, Carlton M. Caves
We use quantum discord to characterize the correlations present in the quantum computational model DQC1, introduced by Knill and Laflamme [Phys. Rev. Lett. 81, 5672 (1998)]. The mo…
