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…
Superconducting vortex-charge measurement using cavity electromechanics
Sudhir Kumar Sahu, Supriya Mandal, Sanat Ghosh +2
As the magnetic field penetrates the surface of a superconductor, it results in the formation of flux-vortices. It has been predicted that the flux-vortices will have a charged vor…
Quantized conductance with non-zero shot noise as a signature of Andreev edge state
Manas Ranjan Sahu, Arup Kumar Paul, Jagannath Sutradhar +6
Electrical conductance measurements have limited scope in identifying Andreev edge states (AESs), which form the basis for realizing various topological excitations in quantum Hall…
Coplanar cavity for strong coupling between photons and magnons in van der Waals antiferromagnet
Supriya Mandal, Lucky N. Kapoor, Sanat Ghosh +6
We investigate the performance of niobium nitride superconducting coplanar waveguide resonators towards hybrid quantum devices with magnon-photon coupling. We find internal quality…
Large flux-mediated coupling in hybrid electromechanical system with a transmon qubit
Tanmoy Bera, Sourav Majumder, Sudhir Kumar Sahu +1
Control over the quantum states of a massive oscillator is important for several technological applications and to test the fundamental limits of quantum mechanics. Addition of an…
Elastic properties of few unit cell thick superconducting crystals of BiSrCaCuO
Sudhir Kumar Sahu, Digambar Jangade, Arumugam Thamizhavel +2
We present systematic measurements of the mechanical properties of few unit cell (UC) thick exfoliated crystals of a high-T cuprate superconductor BiSrCaCuO…
