  Electron spins in silicon quantum dot platform provide great potential for
quantum information processing due to excellent physical properties and modern
fabrication technologies. Spin-based quantum bit (qubit) operations are
intensively studied to realize universal logic gates with a high fidelity, fast
gating operations, and basic programmability. Although recent experimental
achievements can be considered as remarkable results for utilizing quantum
computation, more advanced quantum information protocols should be demonstrated
with a large number of qubit system to enable programmability of silicon
devices. Here, we computationally explore entanglement-based quantum
information protocols in electrically defined five silicon quantum dot system.
To this end, device simulations are employed to demonstrate $1$-qubit gate and
$2$-qubit gate operations. Additionally, we discuss the implementations of
three applications: the generation of magic states, entanglement swapping, and
quantum teleportation in our silicon device. All the results will secure the
scalability of quantum information processing with electron spin qubits in
silicon quantum dot system.
