We propose a method of generating fully entangled electron spin pairs usingan open static quantum dot and a moving quantum dot, realized by thepropagation of a surface acoustic wave (SAW) along a quasi-one-dimensionalchannel in a semiconductor heterostructure. In particular, we consider a staticdot (SD) loaded with two interacting electrons in a singlet state anddemonstrate a mechanism which enables the moving SAW-dot to capture and carryalong one of the electrons, hence yielding a fully entangled static-flyingpair. We also show how with the same mechanism we can load the SD with one ortwo electrons which are initially carried by a SAW-induced dot. The feasibilityof realizing these ideas with existing semiconductor technology is demonstratedand extended to yield flying or static pairs that are fully entangled andarbitrary interconversion of static and flying electron spin qubits.Comment: 6 pages, 5 figure
