Finite-time quantum correlations of propagating squeezed microwaves
2017 · arXiv (Cornell University)
Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of incompatible observables between two subsystems. At the same time, these subsystems themselves may contain no quantum signatures in their self-correlations. These properties …

On-demand generation of traveling cat states using a parametric oscillator
2019 · Physical Review A
We theoretically propose a method for on-demand generation of traveling Schr\"odinger cat states, namely, quantum superpositions of distinct coherent states of traveling fields. This method is based on deterministic generation of intracavity cat states using …

Finite-time quantum entanglement in propagating squeezed microwaves
2018 · LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)
Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of non-commuting observables between two subsystems. At the same time, these subsystems themselves may contain no quantum signatures in their self-correlations. These properties …

Fast Readout and Reset of a Superconducting Qubit Coupled to a Resonator with an Intrinsic Purcell Filter
2022 · Physical Review Applied
Quantum information processing requires qubits that can retain their energy for a long time, and one also needs to be able to rapidly manipulate and measure the qubits. The authors utilize the spatial extent of …
