Secure Transmission of Information Through Quantum Communication

Michael Vasilyev’s goals in his research are simply stated: increase by tenfold the amount of information that can be securely transmitted via the Internet and the distance over which that data can be transmitted.

Quintessential Effects of Quantum Optics Demonstrated with Microwaves

Quantum mechanics, famously, is full of effects that defy our basic intuition. A fine example is the Hong-Ou-Mandel effect, which occurs when two light quanta (or, photons) arrive simultaneously at a so-called beam splitter.

IQOQI Researchers Close Local Realistic Loophole in Photonic Systems of Quantum Entanglement

In everyday life it is only natural that the properties of objects exist independent of being observed or not. The quantum world on the other hand is ruled by other laws: the property of a particle may be defined not until the instant it is being measured, and two entangled particles seem to be connected in a non-local way over large distances.

Dark Matter Detected Onboard the International Space Station

In science fiction, finding antimatter on board your spaceship is not good news. Usually, it means you're moments away from an explosion.

Novel Photonic Floquet Topological Insulator Developed at Technion

Researchers at the Technion-Israel Institute of Technology have developed and successfully demonstrated a photonic Floquet topological insulator, a new device used to protect the transport of light through a unique, lattice of 'waveguides.' The advancement may play a key role in the photonics industry. A description is published in the current issue of NATURE (11 April 2013).
