1. We use Python based quantum program set, QuTip, to simulate spectrum of new type fluxonium superconducting qubits. We further use three dimensional microwave simulator, HFSS, to design and simulate the electromagnetic environment of superconducting qubit chips.
2. We utilize e-beam lithography system to fabricate core of superconducting qubits chips. We also use photo resist processing, metal-oxides deposition systems, etching and developing facility to fabrice fluxonium superconducting qubits chips. The coherence time of qubits can reach 50 micro-seconds.
3. We built ultra-low temperature dilution refrigerator with full capability of frequency domain and time domain microwave measuring system. We can control, readout superconducting qubits. The superconducting quantum chips can further perform quantum task of quantum computation. We can further characterize properties and quality of quantum chips.
