Giant optical nonlinearities from Rydberg-excitons in semiconductor microcavities
Valentin Walther, Robert Johne, Thomas Pohl
The realization of exciton-polaritons -- hybrid excitations of semiconductor quantum well excitons and cavity photons -- has been of great technological and scientific significance…
Control of the electromagnetic environment of a quantum emitter by shaping the vacuum field in a coupled-cavity system
Robert Johne, Ron Schutjens, Sartoon Fattah poor +2
We propose a scheme for the ultrafast control of the emitter-field coupling rate in cavity quantum electrodynamics. This is achieved by the control of the vacuum field seen by the…
Dynamically controlling the emission of single excitons in photonic crystal cavities
Francesco Pagliano, YongJin Cho, Tian Xia +3
Single excitons in semiconductor microcavities represent a solid-state and scalable platform for cavity quantum electrodynamics (c-QED), potentially enabling an interface between f…
Ultrafast nonlocal control of spontaneous emission
Chao-Yuan Jin, Robert Johne, Milo Y. Swinkels +4
Solid-state cavity quantum electrodynamics systems will form scalable nodes of future quantum networks, allowing the storage, processing and retrieval of quantum bits, where a real…
Proposal of a two-qubit quantum phase gate for quantum photonic integrated circuits
Robert Johne, Andrea Fiore
We propose a protocol for two-qubit quantum phase gate based upon reflection of photon pulses from a quantum dot in a cavity. Depending on the state of the quantum dot the reflecte…
All-optical control of the spontaneous emission of quantum dots using coupled-cavity quantum electrodynamics
C. Y. Jin, M. Y. Swinkels, R. Johne +4
We demonstrate the remote all-optical control of the spontaneous emission (SE) of quantum dots using coupled photonic crystal cavities. By spectrally tuning a Fabry-Perot cavity in…
