A superconducting quantum interference device (SQUID) comprising 0- and$\pi$-Josephson junctions (JJs), called $\pi$-SQUID, is studied by theresistively shunted junction model. The $\pi$-SQUID shows half-integerShapiro-steps (SS) under microwave irradiation at the voltage $V$ =$(\hbar/2e)\Omega (n/2)$, with angular frequency $\Omega$ and half-integer$n$/2 in addition to integer $n$. We show that the $\pi$-SQUID can be a$\pi$-qubit with spontaneous loop currents by which the half-integer SS areinduced. Making the 0- and $\pi$-JJs equivalent is a key for the half-integerSS and realizing the $\pi$-qubit.
