Distributing quantum information between remote systems will necessitate the integration of
emerging quantum components with existing communication infrastructure. This requires …

Discrete frequency modes, or bins, present a blend of opportunities and challenges for
photonic quantum information processing. Frequency-bin-encoded photons are readily …

An on-demand source of bright entangled photon pairs is desirable for quantum key
distribution (QKD) and quantum repeaters. The leading candidate to generate such pairs is …

The scalability of quantum networking will benefit from quantum and classical
communications coexisting in shared fibers, the main challenge being spontaneous Raman …

We study the coexistence of energy-time entanglement with fiber-optical communication in
the telecom C band. The property of noise from wavelength-multiplexed classical channels …

Because noise is inherent to all measurements, optical communication requires error
identification and correction to protect and recover user data. Yet, error correction, routinely …

The success of a future quantum internet will rest in part on the ability of quantum and
classical signals to coexist in the same optical fiber infrastructure, a challenging endeavor …

The development of prototype metropolitan-scale quantum networks is underway and
entails transmitting quantum information via single photons through deployed optical fibers …

The ability to distribute entanglement between quantum nodes may unlock new capabilities
in the future that include teleporting information across multinode networks, higher …

We present a source of indistinguishable photons at telecom wavelength, synchronized to
an external clock, for the use in distributed quantum networks. We characterize the …
