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

Communication security has to evolve to a higher plane in the face of the threat from the
massive computing power of the emerging quantum computers. Quantum secure direct …

Entanglement purification is a very important element for long-distance quantum
communication. Different from all the existing entanglement purification protocols (EPPs) in …

A monochromatic laser pum** a parametric down-conversion crystal generates frequency-
entangled photon pairs. We study this experimentally by addressing such frequency …

Interferometry using discrete energy levels of nuclear, atomic, or molecular systems is the
foundation for a wide range of physical phenomena and enables powerful techniques such …

The dynamical behavior of Kerr optical frequency combs is very well understood today from
the perspective of the semiclassical approximation. These combs are obtained by pum** …

Over the last two decades, integrated photonics has profoundly revolutionized the domain of
quantum technologies. The ongoing second quantum revolution stands as a timely …

Quantum technologies, if scaled into a high-dimensional Hilbert space, can dramatically
enhance connection capabilities with supporting higher bit rates and ultrasecure information …

Large-scale quantum networks require dynamic and resource-efficient solutions to reduce
system complexity with maintained security and performance to support growing number of …

We present a simple protocol for complete analysis of 16 hyperentangled Bell states of two-
