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…

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…

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…

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…
