We report the operation of AND, EXOR, EXNOR, and inverting gates in a circuit architecture suitable for the set of all Boolean gates. Series arrays of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} dc superconducting quantum interference devices with integrated coils exhibit sufficient modulation to allow low-speed tests demonstrating gate logic, and lack of oscillation or latching. The best inverter operated (without load) at 36 {mu}V, with 2 nW of gate dissipation.
