Distributing quantum information between remote systems will necessitate the integration of emerging components with existing communication infrastructure. This requires understanding channel-induced degradations transmitted signals, beyond typical characterization methods for classical systems. Here we report on a comprehensive Boston-Area Quantum Network (BARQNET) telecom fiber testbed, measuring time-of-flight, polarization, and phase noise imparted signals. We further design demonstrate...
Realizing a quantum network will require long-lived memories with optical interfaces incorporated into scalable architecture. Color-center emitters in diamond have emerged as promising memory modality due to their properties and compatibility integration. However, developing color-center emitter module requires significant advances the areas of heterogeneous integration cryogenically compatible packaging. Here we report on stable for use. This is development towards advanced networking...
A central challenge in quantum networking is transferring states between different physical modalities, such as flying photonic qubits and stationary memories. One implementation entails using spin–photon interfaces that combine solid-state spin qubits, color centers diamond, with nanostructures. However, while high-fidelity interactions have been demonstrated on isolated devices, building practical repeaters requires scaling to large numbers of yet be realized. Here, we demonstrate...
Precision synchronization is vital for robust long-distance quantum networking over fiber and free-space channels which high-fidelity entanglement swapping between separate sources via an optical Bell state measurement requires temporal overlap of photonic qubits arriving from either source. This challenge particularly distinct in satellite-based distribution relative motion, channel effects, propagation delay must be addressed. work presents a precision method free space distribution,...

In this work, we demonstrate saturated photon detection efficiency with narrow NbN nanowires and SNAPs to boost the signal-to-noise ratio, a stabilizing choke inductance that is part of optically-active area.
