[hal-00638468, v1] Back and forth nudging for quantum state estimation by continuous weak measurement
We propose to apply the Back and Forth Nudging (BFN) method used for geophysical data assimilations [1] to estimate the initial state of a quantum system. We consider a cloud of atoms interacting with a magnetic field while a single observable is being continuously measured over time using homodyne detection. The BFN method relies on designing an observer forward and backwards in time. The stat...
متن کاملEfficient quantum-state estimation by continuous weak measurement and dynamical control.
We demonstrate a fast, robust, and nondestructive protocol for quantum-state estimation based on continuous weak measurement in the presence of a controlled dynamical evolution. Our experiment uses optically probed atomic spins as a test bed and successfully reconstructs a range of trial states with fidelities of approximately 90%. The procedure holds promise as a practical diagnostic tool for ...
متن کاملQuantum state tomography via compressed sensing.
We establish methods for quantum state tomography based on compressed sensing. These methods are specialized for quantum states that are fairly pure, and they offer a significant performance improvement on large quantum systems. In particular, they are able to reconstruct an unknown density matrix of dimension d and rank r using O(rdlog²d) measurement settings, compared to standard methods that...
متن کاملContinuous weak measurement of quantum coherent oscillations
We consider the problem of continuous quantum measurement of coherent oscillations between two quantum states of an individual two-state system. It is shown that the interplay between the information acquisition and the backaction dephasing of the oscillations by the detector imposes a fundamental limit, equal to four, on the signal-to-noise ratio of the measurement. The limit is universal, e.g...
متن کاملAdaptive Compressed Sensing Using Sparse Measurement Matrices
Compressed sensing methods using sparse measurement matrices and iterative message-passing recovery procedures are recently investigated due to their low computational complexity and excellent performance. The design and analysis of this class of methods is inspired by a large volume of work on sparsegraph codes such as Low-Density Parity-Check (LDPC) codes and the iterative Belief-Propagation ...
