Schmidt quantum compressor
Israel F. Araujo, Hyeondo Oh, Nayeli A. Rodríguez-Briones +1
This work introduces the Schmidt quantum compressor, an innovative approach to quantum data compression that leverages the principles of Schmidt decomposition to encode quantum inf…
Continuous variable entanglement in a cold-atoms mirrorless optical parametric oscillator
G. C. Borba, R. S. N. Moreira, L. S. Cruz +3
In this work, we explore both the internal and external atomic degrees of freedom to observe quantum entanglement between the modes produced by a mirrorless optical parametric osci…
Non-Markovian to Markovian decay in structured environments with correlated disorder
Mariana O. Monteiro, Nadja K. Bernardes, Eugene M. Broni +2
Manipulating the dynamics of open quantum systems is a crucial requirement for large-scale quantum computers. Finding ways to overcome or extend decoherence times is a challenging…
Enhancing non-classical correlations for light scattered by an ensemble of cold two-level atoms
Lucas S. Marinho, Michelle O. Araújo, Wellington Martins +1
We report the enhancement of quantum correlations for biphotons generated via spontaneous four-wave mixing in an ensemble of cold two-level atoms. This enhancement is based on the…
Cooperative atomic emission from a line of atoms interacting with a resonant plane surface
Michelle O. Araujo, Joao Carlos de Aquino Carvalho, Philippe W. Courteille +1
Cooperative effects such as super- and subradiance can be observed in the fluorescence emitted by a system of N atoms in vacuum, after interaction with a laser beam. In the vicinit…
Quantum-state texture and gate identification
Fernando Parisio
We introduce and explore the notion of texture of an arbitrary quantum state, in a selected basis. In the first part of this letter we develop a resource theory and show that state…
