This theory paper proposed a superconducting-ferroelectric-superconducting Josephson junction whose history-dependent ferroelectric polarization modulates the junction critical current, and used it to formulate a memory-integrated phase-qubit concept.
Key Results
- Derived a coupled Josephson-junction and ferroelectric-barrier Hamiltonian and equivalent circuit description
- Predicted history-dependent critical-current and voltage behavior from the ferroelectric polarization state
- Presented a memory-integrated phase qubit as a theoretical device concept rather than an experimental processor result
