Next Generation Qubits

We explore superconducting qubits for purposes of quantum computation, focusing on improved elements of a quantum computer rather than implementation of small algorithms. The current standard superconducting qubit is the Transmon, made of a capacitor and Josephson junction; however there exists potential for many more qubits. We are interested in developing the next generation of qubits that are more insensitive to relaxation and dephasing loss mechanisms. Our current work includes implementing new circuit designs, such as the 0-pi circuit, and investigating new materials, exampled by the demonstration of a fluxonium qubit with a NbTiN nanowire inductor.
