We present a new quantum computing protocol using Fermionic qubits. This method enables deterministic quantum computation in solid-state systems by simplifying measurements and eliminating the need for two-qubit gates.

Area of Science:

  • Quantum Computing
  • Solid-State Physics
  • Quantum Information Science

Background:

  • Deterministic quantum computing is crucial for scalable quantum computers.
  • Current methods often rely on complex two-qubit gates.
  • Implementing quantum logic in solid-state systems presents significant challenges.

Purpose of the Study:

  • To propose a protocol for partial Bell-state measurements of Fermionic qubits.
  • To enable deterministic quantum computing in solid-state systems.
  • To simplify the experimental realization of quantum computers.

Main Methods:

  • Utilizing two spin qubits in a double quantum dot with different Zeeman splittings.
  • Implementing resonant tunneling between dots only for antiparallel spins.
