Detecting changes to sub-diffraction objects with quantum-optimal speed and accuracy
Michael R Grace, Saikat Guha, Zachary Dutton
Detecting if and when objects change is difficult in passive sub-diffraction imaging of dynamic scenes. We consider the best possible tradeoff between responsivity and accuracy for…
Approaching Quantum Limited Super-Resolution Imaging without Prior Knowledge of the Object Location
Michael R Grace, Zachary Dutton, Amit Ashok +1
A recently identified class of receivers which demultiplex an optical field into a set of orthogonal spatial modes prior to detection can surpass canonical diffraction limits on sp…
Attaining the quantum limit of super resolution in imaging an object's length via pre-detection spatial mode sorting
Zachary Dutton, Ronan Kerviche, Amit Ashok +1
Recent work considered the ultimate (quantum) limit of the precision of estimating the distance between two point objects. It was shown that the performance gap between the quantum…
Modeling coherent errors in quantum error correction
Daniel Greenbaum, Zachary Dutton
Analysis of quantum error correcting codes is typically done using a stochastic, Pauli channel error model for describing the noise on physical qubits. However, it was recently fou…
Efficiency of an enhanced linear optical Bell-state measurement scheme with realistic imperfections
Stephen Wein, Khabat Heshami, Christopher A. Fuchs +4
We compare the standard 50%-efficient single beam splitter method for Bell-state measurement to a proposed 75%-efficient auxiliary-photon-enhanced scheme [W. P. Grice, Phys. Rev. A…
Optimal Measurements for Symmetric Quantum States with Applications to Optical Communication
Hari Krovi, Saikat Guha, Zachary Dutton +1
The minimum probability of error (MPE) measurement discriminates between a set of candidate quantum states with the minimum average error probability allowed by quantum mechanics.…
