Kinetic Inductance Measurement of 2D Superconductors Using Microwave Techniques
IEEE Student Branch Chapter DU is delighted to host a seminar titled, “𝑲𝒊𝒏𝒆𝒕𝒊𝒄 𝑰𝒏𝒅𝒖𝒄𝒕𝒂𝒏𝒄𝒆 𝑴𝒆𝒂𝒔𝒖𝒓𝒆𝒎𝒆𝒏𝒕 𝒐𝒇 𝑺𝒖𝒑𝒆𝒓𝒄𝒐𝒏𝒅𝒖𝒄𝒕𝒐𝒓𝒔 𝑼𝒔𝒊𝒏𝒈 𝑴𝒊𝒄𝒓𝒐𝒘𝒂𝒗𝒆 𝑻𝒆𝒄𝒉𝒏𝒊𝒒𝒖𝒆𝒔”. The seminar will be held on 𝟮𝟯𝗿𝗱 𝗝𝗮𝗻𝘂𝗮𝗿𝘆, 𝟮𝟬𝟮𝟯, at 2.00 PM, at Department of EEE, University of Dhaka. The speaker will also be sharing her exciting journey to MIT. The Massachusetts Institute of Technology (MIT) is a private land-grant research institution in Cambridge, Massachusetts. The most prestigious and highly ranked academic institutions in the world, MIT has contributed significantly to the advancement of contemporary technology and science. Although MIT’s engineering and physical science departments are likely its most well-known strengths, other disciplines, such as economics, political science, urban studies, linguistics, and philosophy, are also strong at the university.
Superconducting qubits are a leading qubit platform due to their extensibility, controllability, and high-fidelity gate operations. However, to realize the promise of quantum computation, further improvements in qubit coherence and extensibility will be required. This challenge can be addressed in part by using two-dimensional van der Waals (vdW) materials as superconductor in quantum circuits. Our experimental approach will measure the “kinetic inductance” 2D superconductors using circuit quantum electrodynamics (cQED) architecture.
High-quality vdW heterostructures enable the construction of small form-factor superconducting quantum devices by reducing the qubit area and exhibiting comparable coherence. Superconductors feature a substantial kinetic inductance, essentially the kinetic energy stored in the supercurrent and related to the superfluid density of the Cooper pairs. The kinetic inductance of 2D superconductors can be calculated by measuring the frequency shift of a standard Aluminum coplanar waveguide resonator terminated by the device. Understanding the kinetic inductance of NbSe2 enables the design of “protected” qubits such as fluxonium and zero-pi qubits.
