A quantum treatment of the Stern-Gerlach experiment
K. M. Fonseca-Romero
Most textbooks introduce the concept of spin by presenting the Stern-Gerlach experiment with the aid of Newtonian atomic trajectories. However, to understand how both spatial and s…
Partial and complete qubit estimation using a single observable: optimization and quantum simulation
Cristian A. Galvis Florez, J. Martínez-Cifuentes, K. M. Fonseca-Romero
Quantum state estimation is an important task of many quantum information protocols. We consider two families of unitary evolution operators, one with a one-parameter and the other…
Classical models may be a better explanation of the Jiuzhang 1.0 Gaussian Boson Sampler than its targeted squeezed light model
Javier Martínez-Cifuentes, K. M. Fonseca-Romero, Nicolás Quesada
Recently, Zhong et al. performed landmark Gaussian boson sampling experiments with up to 144 modes using threshold detectors. The authors claim to have achieved quantum computation…
Spin-state estimation using the Stern-Gerlach experiment
Javier Martínez-Cifuentes, K. M. Fonseca-Romero
We propose a state estimation scheme for spins, using a modified setup of the Stern-Gerlach experiment, in which a beam of neutral spin-1/2 point particles interacts with a quadrup…
Single plane minimal tomography of double slit qubits
Edwin C. Chaparro Sogamoso, D. Angulo, K. M. Fonseca-Romero
The determination of the density matrix of an ensemble of identically prepared quantum systems by performing a series of measurements, known as quantum tomography, is minimal when…
Anisotropic Dirac cones in monatomic hexagonal lattices
A. M. Rojas-Cuervo, K. M. Fonseca-Romero, R. R. Rey-González
In the last few years, the fascinating properties of graphene have been thoroughly investigated. The existence of Dirac cones is the most important characteristic of the electronic…
