Measurement-based quantum computation using two-component BECs

Abstract: We propose measurement-based quantum computation (MBQC) using two-component Bose-Einstein condensates (BECs). When constructing our theory, we need to introduce creation operator and annihilation operator for MBQC. This is realized by considering the Stokes operator (Schwinger boson). As a result, we find that the state after a measurement depends on the number of particles.
