Hexapartite entanglement in an above-threshold Optical Parametric Oscillator
F. A. S. Barbosa, A. S. Coelho, L. F. Muñoz Martínez +4
We demonstrate, theoretically and experimentally, the generation of hexapartite modal entanglement by the optical parametric oscillator (OPO) operating above the oscillation thresh…
Uniqueness of the joint measurement and the structure of the set of compatible quantum measurements
Leonardo Guerini, Marcelo Terra Cunha
We address the problem of characterising the compatible tuples of measurements that admit a unique joint measurement. We derive a uniqueness criterion based on the method of pertur…
Optimal control of universal quantum gates in a double quantum dot
Leonardo K. Castelano, Emanuel F. de Lima, Justino R. Madureira +2
We theoretically investigate electron spin operations driven by applied electric fields in a semiconductor double quantum dot (DQD). Our model describes a DQD formed in semiconduct…
Exploring six modes of an optical parametric oscillator
Luis F. Muñoz-Martínez, Felippe Alexandre Silva Barbosa, Antônio Sales Coelho +4
We measure the complete quantum state for six modes of the electromagnetic field produced by an optical parametric oscillator. The investigation involves the sideband of the intens…
Noncontextual wirings
Barbara Amaral, Adán Cabello, Marcelo Terra Cunha +1
Contextuality is a fundamental feature of quantum theory and is necessary for quantum computation and communication. Serious steps have therefore been taken towards a formal framew…
Operational framework for quantum measurement simulability
Leonardo Guerini, Jessica Bavaresco, Marcelo Terra Cunha +1
We introduce a framework for simulating quantum measurements based on classical processing of a set of accessible measurements. Well-known concepts such as joint measurability and…
Most incompatible measurements for robust steering tests
Jessica Bavaresco, Marco Túlio Quintino, Leonardo Guerini +3
We address the problem of characterizing the steerability of quantum states under restrictive measurement scenarios, i.e., the problem of determining whether a quantum state can de…
Proposal for Automated Operations for Single-Photon Multipath Qudits
Roberto D. Baldijão, Gilberto F. Borges, Breno Marques +3
We propose a method for implementing automated state transformations on single-photon multipath qudits encoded in a one-dimensional transverse spatial domain. It relies on transfer…
Phase collapse and revival of a 1-mode Bose-Einstein condensate induced by an off-resonant optical probe field and superselection rules
L. G. E. Arruda, G. A. Prataviera, M. C. de Oliveira
Phase collapse and revival for Bose-Einstein condensates is a nonlinear phenomena appearing due atomic collisions. While it has been observed in a general setting involving many mo…
