Efficient Photon Transfer in a Three‐Mode System via Periodic Modulation of an Intermediate Mode

Efficient and robust quantum state transfer between distinct optical modes is a cornerstone for on‐chip quantum networks and integrated quantum information processing. Here, we propose a protocol for fast photon transfer in a three‐mode system consisting of two optical cavities and an intermediate bosonic mode that is...

Polariton Bell Node for Quantum Repeaters

We propose a Bell-measurement node for quantum repeaters based on a planar semiconductor microcavity operating in the strong-coupling regime. Cavity photons hybridize with quantum-well excitons to form polaritons combining properties of photons and matter quasiparticles. A control photon loaded into one polariton mode...

Efficient detection of spectral cluster states

Multimode entangled states of light are key resources for high-dimensional photonic quantum technologies, particularly for continuous-variable quantum computing and quantum information processing. Exploiting their full capabilities requires detection strategies that can efficiently and simultaneously access a large num...

Dissipation-assisted steady-state entanglement preparation in a hybrid quantum system

Hybrid quantum systems that integrate complementary advantages of different physical platforms provide a new pathway toward large-scale, fault-tolerant quantum information processing. In this work, we theoretically investigate a hybrid system consisting of a Rydberg atom, a piezoelectric nanomechanical resonator, and a...

Input-Output Analysis of Quantum Dot SUPER Excitation

The Swing-UP of the quantum EmitteR population (SUPER) two-color pulsed excitation scheme allows for robust and close to 100\% excitation of a two-level quantum emitter using only red detuned light. We analyze the underlying counterintuitive dynamics using a full quantum input-output description of the in- and outgoing...

Interference-engineered shortcut to perfect state transfer

Achieving fast, high-fidelity state transfer is fundamental to scalable integrated photonics and quantum information processing. While adiabatic evolution provides inherent robustness against control and fabrication imperfections, its requirement for slow driving leads to impractically long propagation distances in pho...
