Quantifying Pauli Errors in Single-Photon Resource-State Generation
Yuktee Gupta, Andrew C. Doherty, Sahand Mahmoodian
We propose a scheme to compute Pauli error rates in photonics-based quantum error correction using experimental observables of single photons produced from quantum emitters. We sho…
Non-Gaussian Photon Correlations in Weakly Coupled Atomic Ensembles
Yangming Wang, Sahand Mahmoodian
We develop a scattering theory formalism and use it to predict that a resonantly driven atomic ensemble weakly coupled to an optical mode can generate light with non-Gaussian corre…
Dynamic stimulated emission for deterministic addition and subtraction of propagating photons
Haoyuan Luo, Parth S. Shah, Frank Yang +2
Photon subtraction and addition are essential non-Gaussian processes in quantum optics, where conventional methods using linear optics and number-resolving detection often suffer f…
Emergence of unidirectionality and phase separation in optically dense emitter ensembles
Kasper J. Kusmierek, Max Schemmer, Sahand Mahmoodian +1
The transmission of light through an ensemble of two-level emitters in a one-dimensional geometry is commonly described by one of two emblematic models of quantum electrodynamics (…
Efficient optical cat state generation using squeezed few-photon superposition states
Haoyuan Luo, Sahand Mahmoodian
Optical Schrödinger cat states are non-Gaussian states with applications in quantum technologies, such as for building error-correcting states in quantum computing. Yet the effici…
