Dark state spectroscopy in nonlinear waveguide quantum electrodynamics

Shay Nadel, Amir Sivan, Aviv Karnieli

Quantum systems face a fundamental trade-off: they must remain decoupled from the environment to maintain long coherence times, yet they require interactions with the environment t…

Cooperative Emission from Quantum Emitters in Hexagonal Boron Nitride Layers

Igor Khanonkin, Amir Sivan, Le Liu +5

Collective light emission from many-body quantum systems is a cornerstone of quantum optics, yet its implementation in solid-state platforms operating under ambient conditions rema…

Hyperentanglement in Nanophotonic Systems with Discrete Rotational Symmetry

Lior Fridman, Amit Kam, Amir Sivan +3

We propose a scheme to generate hyperentanglement between photons carrying angular momentum in nanophotonic systems with discrete rotational symmetry. Coupling free-space photons i…

Spontaneous Emission from Electronic Metastable Resonance States

Amir Sivan, Milan Å indelka, Meir Orenstein +1

We demonstrate that calculating the spontaneous emission decay rate from metastable resonance states (states with finite lifetimes embedded in the continuum) requires considering t…

Adding Photonic Entanglement to Superradiance by Using Multilevel Atoms

Amir Sivan, Meir Orenstein

We show here that the photonic states emitted by ensembles of multilevel atoms via a superradiance process exhibit entanglement in the modal (frequency) degree of freedom, making t…

Tracking the Evolution of Near-Field Photonic Qubits into High-Dimensional Qudits via State Tomography

Amit Kam, Shai Tsesses, Lior Fridman +10

Quantum nanophotonics offers essential tools and technologies for controlling quantum states, while maintaining a miniature form factor and high scalability. For example, nanophoto…
