All-optical Quantum State Engineering for Rotation-symmetric Bosonic States

Rajveer Nehra, Miller Eaton, Olivier Pfister +1

Continuous-variable quantum information processing through quantum optics offers a promising platform for building the next generation of scalable fault-tolerant information proces…

Generalized overlap quantum state tomography

Rajveer Nehra, Miller Eaton, Carlos González-Arciniegas +5

We propose and experimentally demonstrate a quantum state tomography protocol that generalizes the Wallentowitz-Vogel-Banaszek-Wódkiewicz point-by-point Wigner function reconstruct…

Characterizing quantum detectors by Wigner functions

Rajveer Nehra, Kevin Valson Jacob

We propose a method for characterizing a photodetector by directly reconstructing the Wigner functions of the detector's Positive-Operator-Value-Measure (POVM) elements. This metho…

State-independent quantum tomography of a single-photon state by photon-number-resolving measurements

Rajveer Nehra, Aye Win, Miller Eaton +6

The Wigner quasiprobability distribution of a narrowband single-photon state was reconstructed by quantum state tomography using photon-number-resolving measurements with transitio…

Non-Gaussian and Gottesman-Kitaev-Preskill state preparation by photon catalysis

Miller Eaton, Rajveer Nehra, Olivier Pfister

Continuous-variable quantum-computing (CVQC) is the most scalable implementation of QC to date but requires non-Gaussian resources to allow exponential speedup and quantum correcti…
