Occupation-selective photon-pair interactions in a flux-pumped SQUID resonator
L. N. Ferreira, D. Z. Rossatto, A. S. M. de Castro +1
Flux-pumped Josephson circuits provide a versatile platform for parametric photon generation and multimode bosonic control. We identify an occupation-conditioned pair interaction t…
Quantum phase estimation for nondestructive monitoring and Wigner tomography of bosonic fields
Lucas R. S. Santos, Ciro M. Diniz, Daniel Z. Rossatto +1
Quantum phase estimation is usually introduced as an algorithmic primitive for extracting eigenphases of unitary operators. Here we show that, when implemented through a dispersive…
Preparation of Large Fock States in Resonators with High Probability
Lucas R. S. Santos, Ciro M. Diniz, Daniel Z. Rossatto +1
Large Fock states are important resources for bosonic quantum information and quantum-enhanced metrology, but preparing them with high probability at large excitation numbers remai…
Building Block For Universal Continuous Variables Computation In Superconducting Devices
Bruno A. Veloso, Ciro M. Diniz, Luiz O. R. Solak +3
Continuous variable (CV) quantum computation offers an alternative to qubit-based computing by exploiting the infinite-dimensional Hilbert space of bosonic modes. Despite recent pr…
Quantum Resonator as a Directional Quantum Emitter
Luiz O. R. Solak, Bruno L. Vermes, Antonio S. M. de Castro +2
Single-photon sources are essential for testing fundamental physics and for the development of quantum technologies. In this work a single-photon source is investigated, based on a…
High Efficiency Storage of Quasi-Classical and Quantum States in Coupled Resonators
Luiz O. R. Solak, Ciro M. Diniz, Daniel Z. Rossatto +3
We propose an optical model in which both quantum and quasi-classical states can be ideally stored using coupled resonators. The protocol is based on a time-dependent coupling betw…
