Ion exchange in glass has a long history as a simple and effective technology to produce
gradient-index structures and has been largely exploited in industry and in research …

Fiber-optic Mach–Zehnder interferometers are widely used in research areas such as
telecommunications, spectroscopy, and quantum information. These optical structures are …

Quantum walk is a key operation in quantum computing, simulation, communication and
information. Here, we report for the first time the demonstration of quantum walks and …

We analyze autocompensation possibilities in entanglement-based QKD protocols. In
particular, we study the seminal BBM92 protocol and find that an autocompensating …

The integrated radar jamming and secure communication system providing both false target
and high physical layer transmission security will play an important role in future electronic …

We present a communication system based on quantum degenerate four-wave mixing for
achieving fully autocompensating high-dimensional quantum cryptography. We prove that …

Single photon or biphoton states propagating in optical fibers or in free space are affected by
random perturbations and imperfections that disturb the information encoded in such states …

This paper reports a photonics-assisted millimeter-wave (mm-wave) joint radar jamming and
secure communication system constructed through a photonic upconversion technique. In …

Ion-exchanged glass as a platform for quantum photonics is proposed. Quantum projectors
are implemented with integrated optical directional couplers fabricated by ion-exchange …
