Implementing a practical quantum secure direct communication system
Quantum secure direct communication (QSDC) is an important branch of quantum communication, based on the principles of quantum mechanics for the direct transmission of classified information. While recent proof-of-principle ...
Nonlinear integrated quantum electro-optic circuits
Physicists envision that the future of quantum computation networks will contain scalable, monolithic circuits, which include advanced functionalities on a single physical substrate. While substantial progress has already ...
When cold atoms meet nano: A wired quantum node
Physicists at the Kastler Brossel Laboratory in Paris have reached a milestone in the combination of cold atoms and nanophotonics. Using fiber-addressable atoms, they have created the first wired atomic entangled state that ...
Next-generation optics in just two minutes of cooking time
Optical circuits are set to revolutionize the performance of many devices. Not only are they 10 to 100 times faster than electronic circuits, but they also consume a lot less power. Within these circuits, light waves are ...
A circuit platform made of strongly interacting microwave photons
A team of researchers at the University of Chicago has developed a circuit platform for the exploration of quantum matter made of strongly interacting microwave photons. In their paper published in the journal Nature, the ...
Interdisciplinary UA researchers get tangled up in quantum computing
Good neighbors often share resources: a cup of sugar, extra lawn chairs, a set of jumper cables. Researchers across campus at the University of Arizona will soon be able to share a less common—and far more valuable—resource ...
Researchers develop direct-write quantum calligraphy in monolayer semiconductors
Scientists at the U.S. Naval Research Laboratory (NRL) and the Air Force Research Laboratory (AFRL) have developed a way to directly write quantum light sources, which emit a single photon of light at a time, into monolayer ...
Breakthrough in photonics—data-transmitting light signal gets power boost from nanosized amplifier
Light is more energy-efficient and a faster way of transferring data than electricity. Until now, the rapid attenuation of light signals in microchips has prevented the use of light as a source of an information signal.
Electron-gun simulations explain the mechanisms of high-energy cosmic rays
A new study published in EPJ D provides a rudimentary model for simulating cosmic rays' collisions with planets by looking at the model of electrons detached from a negative ion using photons. In this work, Chinese physicists ...
