A quantum router architecture for high-fidelity entanglement

The past decade has seen tremendous progress in experimentally realizing the building blocks of quantum repeaters. Repeater architectures with multiplexed quantum memories have been proposed to increase entanglement distribution rates, but an open challenge is to maintain entanglement fidelity over long-distance links. A team of researchers has addressed this topic with a quantum router architecture […]

Linking two independent quantum nodes for future metropolitan quantum networks

Researchers at QuTech have demonstrated a key technology for linking quantum nodes over existing telecom fiber, by realizing quantum interference of photons emitted by quantum devices at telecom wavelengths. The technique also allows for compensating intrinsic differences between the quantum devices. For a quantum network to function it uses a particular quantum effect between the […]

Energy and bandwidth efficiency optimization of quantum-enabled optical communication channels

Bandwidth and energy are two fundamental resources needed to exchange information. In digital communication, information is encoded in a finite set of physical states known as symbols. In optics, modulated laser pulses are often used as information carriers. Indeed, coherent laser light is easy to generate, modulate, and detect even in lossy communication channels. Modulation […]

New QKD stable secure protocol

Based on the so-called Quantum Key Distribution (QKD), researchers at TU Darmstadt have developed a new, tap-proof communication network. The new system is used to exchange symmetric keys between parties in order to encrypt messages so that they cannot be read by third parties. In cooperation with Deutsche Telekom, the researchers led by physics professor […]
