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…
