The three-bit balanced ternary quantum voltage generator was designed and tested. This voltage generator is based on zero-crossing Shapiro steps (ZCSSs) in asymmetric two-junction SQUID. ZCSSs were observed on the current-voltage curves, and maximum and minimum current of ZCSSs were almost same, respectively for the three bits. 27-step quantum voltages from -13Φ0f to +13Φ0f were observed by combinations of inputs of bit1, bit2 and bit3.
