Abstract
Quantization of the critical current has been confirmed in a supercond ucting quantum point contact consisting of a split-gated superconducto r-(two-dimensional electron gas)-superconductor junction. Both the cri tical current and the conductance show a step-wise change as function of the gate voltage.
