A coupled electronic waveguide device is proposed to create a qubit with two computational bases. The qubit has applications in cryptographic systems that are compatible with semiconductor integration. The proposed protocol couples spin polarization with waveguide switching to achieve the encryption for the secure transmission of bits.
