The response characteristic of a quantum high-pass/low-pass filter for quantum state preparation

Haibo Wang, Satoru Odate, Yongmin Li +1 more

We analyse the output characteristic of a quantum high-pass/low-pass filter, which was introduced recently (Wang et al 2005 Phys. Rev. A 72 013822). Various responses of quantum filters with different parameters have been calculated. It is possible to apply these quantum circuits in quantum state preparation.

Cascaded low-pass filters for the measurements of DC characteristics of superconducting qubits

Tie Li

Cascaded low-pass filters are designed and fabricated for the measurements of dc characteristics of superconducting qubits. The filters are cascaded by LCR filter and copper powder filter. At 77 K the cutoff frequency is 120 kHz and the roll-off is -40 dB/decade. We achieved an attenuation -60 dB when the frequency is above 10 MHz. The frequency response of the cascaded filters is better than single LCR filter or copper powder filter and high frequency noise can be suppressed effectively at low temperature.

Generation of a sub-Poissonian state with quantum high- and low-pass filters

Haibo Wang, Yongmin Li, Satoru Odate +1 more

We introduce a quantum component, the quantum high- and low-pass filter, and analyze its output characteristic. It is shown that a quantum bandpass filter can be achieved by using passive linear optics and projection measurements. Furthermore, we show that the sub-Poissonian state can be generated by using a cascaded quantum low-pass filter and high-pass filter.
