Molecular Qubits

Vanadium complexes, chromium complexes, and other transition metal molecules

Trapping Technique

1. Molecules can be trapped in solid matrices: embedded in crystals or frozen solutions
2. Solution-based: molecules in liquid solution at room or low temperature
3. Gas phase: molecules in vacuum, can be laser-cooled and trapped
4. Optical tweezers can trap individual molecules
5. No specific trapping technique required; depends on application
6. Chemical environment can be tuned to optimize qubit properties

Gate Mechanism

1. Single-qubit gates via microwave or radiofrequency pulses
2. Electron spin resonance (ESR) drives electron spin transitions
3. Nuclear magnetic resonance (NMR) for nuclear spin qubits
4. Pulse sequence design controls rotation angle and axis
5. Two-qubit gates via dipolar coupling between nearby molecules
6. Chemical exchange can mediate interactions in solution
7. Optical control possible for molecules with appropriate transitions
