Enhanced Quantum State Transfer via Feedforward Cancellation of Optical Phase Noise. Physical Review Letters, 133(25), Article 253202. https://doi.org/10.1103/PhysRevLett.133.253202

Many experimental platforms for quantum science depend on state control via laser fields. Frequently, however, the control fidelity is limited by optical phase noise. This is exacerbated in stabilized laser systems where high-frequency phase noise is... Read More about Enhanced Quantum State Transfer via Feedforward Cancellation of Optical Phase Noise..

Ultralong-range Cs-RbCs Rydberg molecules: Nonadiabaticity of dipole moments (2024)
Journal Article
