Low-Loss Integrated Nanophotonic Circuits with Layered Semiconductor Materials

Rui Ning Wang, Tobias Kippenberg, Philippe Andreas Rölli, Clément Christian Javerzac-Galy, Junqiu Liu, Arslan Sajid Raja, Jijun He, Mikhail Churaev

Monolayer transition-metal dichalcogenides with direct bandgaps are emerging candidates for optoelectronic devices, such as photodetectors, light-emitting diodes, and electro-optic modulators. Here we report a low-loss integrated platform incorporating mol ...

Evidence of the entanglement constraint on wave-particle duality using the IBM Q quantum computer

Marc-André Dupertuis, Clément Christian Javerzac-Galy, Nicolas Schwaller

We experimentally verify the link existing between entanglement and the amount of wave-particle duality in a bipartite quantum system with superconducting qubits in the IBM Q quantum computer. We consider both pure and mixed states, and study the influence ...

Crystalline materials for microresonator-based quantum optics

Clément Christian Javerzac-Galy

Hybrid quantum systems are composed of different physical components that can perform simultaneously several tasks such as quantum computing, quantum sensing and quantum communication. Photons are at the core of many of the functionalities of these systems ...

Efficient Quantum Algorithms for GHZ and W States, and Implementation on the IBM Quantum Computer

Marc-André Dupertuis, Nicolas Macris, Clément Christian Javerzac-Galy, Kenichi Komagata, Fabien Gremion, Chun Lam Chan, Jarla Thiesbrummel, Romain Fournier

Efficient deterministic algorithms are proposed with logarithmic step complexities for the generation of entangled GHZ(N) and W-N states useful for quantum networks, and an implementation on the IBM quantum computer up to N = 16 is demonstrated. Improved q ...

Excitonic Emission of Monolayer Semiconductors Near-Field Coupled to High-Q Microresonators

Tobias Kippenberg, Nicolas Piro Mastracchio, Clément Christian Javerzac-Galy, Ryan Daniel Schilling, Anshuman Kumar, Sina Khorasani

We present quantum yield measurements of single layer WSe2 (1L-WSe2) integrated with high-Q (Q > 106) optical microdisk cavities, using an efficient (η > 90%) near-field coupling scheme based on a tapered optical fiber. Coupling of the excitonic emission i ...

Quantum cascade laser-based Kerr frequency comb generation

Tobias Kippenberg, Erwan Guillaume Albert Lucas, Clément Christian Javerzac-Galy, John David Jost, Caroline Marie Anne Lecaplain

We report mid-infrared Kerr comb generation based on a quantum cascade laser pumping a crystalline microresonator. For the first time QCL light is coupled into a microresonator via a tapered chalcogenide fiber allowing mid-IR Kerr comb generation. ...
