Partial orbits of quantum gates and full three-particle entanglement
(Springer, 2021-10-20)
We introduce the notion of partial orbit for a given set of elementary quantum gates, and we study the action of different sets of gates on an initially three-particle disentangled state. We analyze the entanglement of the ...
Entanglement, decoherence and estimation in neutrino oscillations
(Universidade Federal de Minas GeraisUFMG, 2017-08-11)
In this work, we studied entanglement and decoherence in neutrino oscillations from a quantum metrology perspective. A summary of the quantum eld theoretic description of neutrinos was done and the main quantum mechanical ...
Entanglement and the ticking of the clock
(Sociedade Brasileira de Física, 2020-06)
The concept of entanglement is at the heart of quantum physics. It plays a central role in all quantum phenomena involving composite systems. Interestingly, there is an intriguing idea that has attracted considerable ...
