Qubit ZooEarly proposal for a position-based semiconductor qubit formed from one electron in two coupled quantum dots. The logical states are predominantly localized in opposite dots, resonant radiation drives one-qubit operations, and electrostatic coupling supplies a proposed two-qubit interaction.
Key Results
- Proposed a one-electron coupled-quantum-dot molecule as a charge-polarization qubit.
- Described resonant one-qubit control, switchable capacitive two-qubit coupling, and polarization readout.
- The preprint was submitted in December 1999 and the archival article appeared in 2000.
