Quantum Simulated Annealing
R. Somma, S. Boixo, H. Barnum
We develop a quantum algorithm to solve combinatorial optimization problems through quantum simulation of a classical annealing process. Our algorithm combines techniques from quan…
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…
Parameter Estimation with Mixed-State Quantum Computation
Rolando D. Somma, Sergio Boixo
We present a quantum algorithm to estimate parameters at the quantum metrology limit using deterministic quantum computation with one bit. When the interactions occurring in a quan…
An operational interpretation for multipartite entanglement
Sergio Boixo, Alex Monras
We introduce an operational interpretation for pure-state global multipartite entanglement based on quantum estimation. We show that the estimation of the strength of low-noise loc…
