"Chirpons": one-dimensional phase singularities as atypical local oscillations
Enrique G. Neyra, Laureano A. Bulus Rossini, Fabián Videla +2
In this work, phase singularities embedded in a wavepacket are shown to act as sources of atypical localized oscillations when the packet interacts with a linear system. We refer t…
Parallelized projective measurements for spatial photonic qudits estimation
Quimey Pears Stefano, Lorena Rebón, Claudio Iemmi
We present a quantum state tomography method that enables the reconstruction of \emph{arbitrary} dimensional quantum states encoded in the discretized transverse momentum of ph…
Tomographic measurement data of states that never existed
Julian Göttsch, Stephan Grebien, Felix Pein +6
Microscopic Schr{ö}dinger cat states are generated from quantum correlated fields using a probabilistic heralding photon subtraction event. Subsequent quantum state tomography prov…
Free temporal evolution of a superbandwidth wave packet: The quantum tale of the hare and the tortoise
Enrique G. Neyra, Marcelo F. Ciappina, Lorena Rebón
Can the interplay between quantum mechanics and classical optics offer new perspectives on wavepacket dynamics? Building on this connection, we show that local momenta with both su…
Group-invariant estimation of symmetric states generated by noisy quantum computers
Federico Holik, Marcelo Losada, Giannina Zerr +2
The problem of quantum state estimation is crucial in the development of quantum technologies. In particular, the use of symmetric quantum states is useful in many relevant applica…
Above-threshold ionization by polarization-crafted pulses
Camilo Granados, Enrique G. Neyra, Lorena Rebón +1
Coherent light has revolutionized scientific research, spanning biology, chemistry, and physics. To delve into ultrafast phenomena, the development of high-energy, high-tunable lig…
Superbandwidth laser pulses in a dispersive medium: oscillating beyond the Fourier spectrum with unexpected propagation features
Enrique G. Neyra, Laureano A. Bulus Rossini, Fabián Videla +2
The concept of superbandwidth refers to the fact that a band-limited signal can exhibit, locally, an increase of its bandwidth, i.e., an effective bandwidth greater than that predi…
Inspecting the use of SLMs for the control of photonic quantum states
Sebastián Bordakevich, Dudbil Pabón, Lorena Rebón +1
Spatial light modulators (SLMs) are widely used to coherently control quantum states of light. When carrying out these experiments, some assumptions are made. For instance, it is s…
Parameterizing density operators with arbitrary symmetries to gain advantage in quantum state estimation
Inés Corte, Marcelo Losada, Diego Tielas +2
In this work, we show how to parameterize a density matrix that has an arbitrary symmetry, knowing the generators of the Lie algebra (if the symmetry group is a connected Lie group…
Principal frequency, super-bandwidth, and low-order harmonics generated by super-oscillatory pulses
Enrique G. Neyra, Demian A. Biasetti, Fabián Videla +2
An alternative definition to the main frequency of an ultra-short laser pulse, named principal frequency (), was recently introduced in E.G. Neyra, et al. Phys. Rev. A 103, 05…
Selective and efficient quantum process tomography for non-trace preserving maps: a superconducting quantum processor implementation
Quimey Pears Stefano, Ignacio Perito, Lorena Rebón
Alternatively to the full reconstruction of an unknown quantum process, the so-called selective and efficient quantum process tomography (SEQPT) allows estimating, individually and…
Optimization for maximum modulation of a double-pass twisted nematic liquid crystal display
Sebastián Bordakevich, Lorena Rebón, Silvia Ledesma
Spatial light modulators are widely used to perform modulations of different properties of the electromagnetic field. In this work, a simple optimization method for general double-…
Experimental characterization of quantum processes: a selective and efficient method in arbitrary finite dimension
Quimey Pears Stefano, Ignacio Perito, Juan José Miguel Varga +2
The temporal evolution of a quantum system can be characterized by quantum process tomography, a complex task that consumes a number of physical resources scaling exponentially wit…
