Quantum Interfaces with Single Molecules

Isolating and addressing individual quantum systems has allowed for breakthrough results in quantum mechanics. Today, increasing the complexity of the experimental system while maintaining control at the single-quantum level is vital for the next generation of quantum devices and research.

QUINTESSEnCE will take up this challenge by developing interfaces between single photons, spins and phonons, all within one simple physical system, i.e. a single molecule.

Electron-phonon coupling in a molecule can be mapped into a unique cavity optomechanical system

We target multi-photon experiments on chip thanks to the demonstrated indistinguishability in the emission from distinct molecules in our group.
