Broadband Kinetic-Inductance Parametric Amplifiers with Impedance Engineering
Chih-Chiao Hung, Hiroki Kutsuma, Chung Wai Sandbo Chang +2
Broadband quantum-limited parametric amplifiers (PAs) are essential components in quantum information science and technology. Impedance-engineered resonator-based PAs and traveling…
Receiver Operating Characteristics for a Prototype Quantum Two-Mode Squeezing Radar
David Luong, C. W. Sandbo Chang, A. M. Vadiraj +3
We have built and evaluated a prototype quantum radar, which we call a quantum two-mode squeezing radar (QTMS radar), in the laboratory. It operates solely at microwave frequencies…
Lattice gauge fields via modulation in circuit QED: The bosonic Creutz ladder
Hadiseh Alaeian, Chung Wai Sandbo Chang, Mehran Vahdani Moghaddam +3
In this work we propose two protocols to make an effective gauge potential for microwave photons in circuit QED. The schemes consist of coupled transmons whose flux are harmonicall…
On-demand microwave generator of shaped single photons
P. Forn-Díaz, C. W. Warren, C. W. S. Chang +2
We demonstrate the full functionality of a circuit that generates single microwave photons on demand, with a wave packet that can be modulated with a near-arbitrary shape. We achie…
