A quantum point contact with one-dimensional subbands described by two quantum numbers has been realized by laterally confining a quasi two-dimensional electron gas of a AlGaAs parabolic quantum well by split-gate electrodes. We measured quantized conductance reflecting the 1D subband structure in t
