Influence of squeezing on the weak-to-strong measurement transition
Kevin Araya-Sossa, Miguel Orszag
In this work, we study the measurement transition for a coherent squeezed pointer state through a transition factor that involves a system-pointer coupling by using an arbitrar…
Generation of entanglement via squeezing on a tripartite-optomechanical system
Kevin Araya-Sossa, Miguel Orszag
We introduce a new strategy to regulate the quantum entanglement in a dispersive-hybrid system where a qubit is directly coupled to a cavity and a resonator. A dramatic transition…
Enhanced discrimination of high-dimensional quantum states by concatenated optimal measurement strategies
M. A. Solís-Prosser, O. Jiménez, A. Delgado +1
The impossibility of deterministic and error-free discrimination among nonorthogonal quantum states lies at the core of quantum theory and constitutes a primitive for secure quantu…
Topological input-output theory for directional amplification
Tomás Ramos, Juan José García-Ripoll, Diego Porras
We present a topological approach to the input-output relations of photonic driven-dissipative lattices acting as directional amplifiers. Our theory relies on a mapping from the op…
Sensing electrochemical signals using a nitrogen-vacancy center in diamond
Hossein T. Dinani, Enrique Muñoz, Jeronimo R. Maze
Chemical sensors with high sensitivity that can be used in extreme conditions and can be miniaturized are of high interest in science and industry. The Nitrogen-vacancy (NV) center…
Photon cooling by dispersive atom-field coupling with atomic postselection
Felipe Oyarce, Miguel Orszag
We propose, in a Ramsey interferometer, to cool the cavity field to its ground state, starting from a thermal distribution by a dispersive atom-field coupling followed by an atomic…
