Collective processes of an ensemble of spin-1/2 particles
Bradley A. Chase, J. M. Geremia
When the dynamics of a spin ensemble are expressible solely in terms of symmetric processes and collective spin operators, the symmetric collective states of the ensemble are prese…
Teleportation fidelity as a probe of sub-Planck phase-space structure
A. J. Scott, Carlton M. Caves
We investigate the connection between sub-Planck structure in the Wigner function and the output fidelity of continuous-variable teleportation protocols. When the teleporting parti…
Efficient feedback controllers for continuous-time quantum error correction
Bradley A. Chase, Andrew J. Landahl, J. M. Geremia
We present an efficient approach to continuous-time quantum error correction that extends the low-dimensional quantum filtering methodology developed by van Handel and Mabuchi [qua…
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…
Ultracompact Generation of Continuous-Variable Cluster States
Nicolas C. Menicucci, Steven T. Flammia, Hussain Zaidi +1
We propose an experimental scheme that has the potential for large-scale realization of continuous-variable (CV) cluster states for universal quantum computation. We do this by map…
