Exploring Quantum Synchronization with a Composite Two-Qubit Oscillator
Gaurav M. Vaidya, Arvind Mamgain, Samarth Hawaldar +4
Synchronization has recently been explored deep in the quantum regime with elementary few-level quantum oscillators such as qudits and weakly pumped quantum Van der Pol oscillators…
Characterising Polariton States in Non-Dispersive Regime of Circuit Quantum Electrodynamics
Arvind Mamgain, Samarth Hawaldar, Athreya Shankar +1
A superconducting qubit coupled to a read-out resonator is currently the building block of multiple quantum computing as well as quantum optics experiments. A typical qubit-resonat…
Quantum efficiency, purity and stability of a tunable, narrowband microwave single-photon source
Yong Lu, Andreas Bengtsson, Jonathan J. Burnett +7
We demonstrate an on-demand source of microwave single photons with 71--99\% intrinsic quantum efficiency. The source is narrowband (300\unite{kHz}) and tuneable over a 600 MHz ran…
Hyperentanglement-enhanced quantum illumination
Ashwith Varadaraj Prabhu, Baladitya Suri, C. M. Chandrashekar
In quantum illumination, the signal mode of light, entangled with an idler mode, is dispatched towards a suspected object bathed in thermal noise and the returning mode, along with…
Mirror, mirror: Landau-Zener-Stuckelberg-Majorana interferometry of a superconducting qubit in front of a mirror
P. Y. Wen, O. V. Ivakhnenko, M. A. Nakonechnyi +7
We investigate the Landau-Zener-Stuckelberg-Majorana interferometry of a superconducting qubit in a semi-infinite transmission line terminated by a mirror. The transmon-type qubit…
Characterizing decoherence rates of a superconducting qubit by direct microwave scattering
Yong Lu, Andreas Bengtsson, Jonathan J. Burnett +8
We experimentally investigate a superconducting qubit coupled to the end of an open transmission line, in a regime where the qubit decay rates to the transmission line and to its o…
