Single-photon induced instabilities in a cavity electromechanical device
Tanmoy Bera, Mridul Kandpal, G. S. Agarwal +1
Cavity-electromechanical systems are extensively used for sensing and controlling the vibrations of mechanical resonators down to their quantum limit. The nonlinear radiation-press…
Instabilities near ultrastrong coupling in microwave optomechanical cavity
Soumya Ranjan Das, Sourav Majumder, Sudhir Kumar Sahu +3
With artificially engineered systems, it is now possible to realize the coherent interaction rate, which can become comparable to the mode frequencies, a regime known as ultrastron…
A fast tunable 3D-transmon architecture for superconducting qubit-based hybrid devices
Sourav Majumder, Tanmoy Bera, Ramya Suresh +1
Superconducting qubits utilize the strong non-linearity of the Josephson junctions. Control over the Josephson nonlinearity, either by a current bias or by the magnetic flux, can b…
SQ-CARS: A Scalable Quantum Control and Readout System
Ujjawal Singhal, Shantharam Kalipatnapu, Pradeep Kumar Gautam +5
Qubits are the basic building blocks of a quantum processor which require electromagnetic pulses in giga hertz frequency range and latency in nanoseconds for control and readout. I…
An optomechanical platform with a 3-dimensional waveguide cavity
Bindu Gunupudi, Soumya Ranjan Das, Rohit Navarathna +3
At low temperatures, microwave cavities are often preferred for the readout and control of a variety of systems. In this paper, we present design and measurements on an optomechani…
Multi-mode ultra-strong coupling in circuit quantum electrodynamics
Sal J. Bosman, Mario F. Gely, Vibhor Singh +3
With the introduction of superconducting circuits into the field of quantum optics, many novel experimental demonstrations of the quantum physics of an artificial atom coupled to a…
Approaching ultra-strong coupling in Transmon circuit-QED using a high-impedance resonator
Sal J. Bosman, Mario F. Gely, Vibhor Singh +3
In this experiment, we couple a superconducting Transmon qubit to a high-impedance microwave resonator. Doing so leads to a large qubit-resonator coupling rate , measur…
