REHOVOT, ISRAEL—July 14, 2014—Weizmann Institute of Science researchers have, for the first time, demonstrated a photonic router – a quantum device based on a single atom that enables routing of single photons by single photons. This achievement, as reported in Science magazine, is another step toward overcoming the difficulties in building quantum computers.

A scheme that uses a single atom to switch the direction of a single photon could pave the way toward quantum computers much more powerful than today’s machines.
The setup is described this week in the online issue of Science by researchers from the Weizmann Institute of Science in Rehovot, Israel. In simple terms, the atom can be in one of two states, either “left” or “right.” If the atom is in the left state, a photon that strikes it from the left will continue on in the same direction, as if it hadn’t hit the atom at all. A photon coming from the right, however, will be reflected back in the direction it came from, and at the same time the interaction will cause the atom to flip from left to right. Left and right can stand in for the 1s and 0s of digital logic.

Though several models predict this behavior and evidence from supernovae points in this direction, actual observations of such pre-explosion outbursts have been rare. In new research led by Dr. Eran Ofek of the Weizmann Institute of Science, scientists found such an outburst taking place a short time — just one month — before a massive star underwent a supernova explosion.

MADRID, Jan. 16, 2018/ The BBVA Foundation Frontiers of Knowledge Award in the Information and Communication Technologies category goes, in this tenth edition, to Shafi Goldwasser, Silvio Micali, Ronald Rivest and Adi Shamir for their “fundamental contributions to modern cryptology, an area of a tremendous impact on our everyday life,” in the words of the jury’s citation. “Their advanced crypto-protocols enable the safe and secure transmission of electronic data, ranging from e-mail to financial transactions. In addition, their work provides the underpinning for digital signatures, blockchains and crypto-currencies,” like Bitcoin.

Some of the world’s best known cryptographers – veterans of the crypto wars of the 1990s – say government access to encryption keys is still a bad idea, but is an issue that will never go away because it’s something intelligence agencies crave.
Speaking at RSA 2015’s Cryptographer’s panel, Whitfield Diffie, who pioneered public-key encryption, says key escrow schemes where government could gain access to encrypted data works mainly to the benefit of government. “They want you to be secure but not against them,” he says.

REHOVOT, Israel, Feb. 12 (UPI)—A group of Israeli, European and U.S. robotics and brain researchers are developing robotic "rats" that can aid during rescue missions.
Based on principles of active sensing adopted widely in the animal kingdom, the multinational team is developing touch technologies, including a "whiskered" robotic rat. The whiskered robot will be able to quickly locate, identify and capture moving objects.
Jan 28, 2016... As our sensory organs register objects and structures in the outside world, they are continually engaged in two-way communication with the brain. In research recently published in Nature Neuroscience, Weizmann Institute of Science researchers found that for rats, which use their whiskers to feel out their surroundings at night, clumps of nerve endings called mechanoreceptors, which are located at the base of each whisker, act as tiny calculators. These receptors continuously compute the way the whisker’s base rotates in its socket, expressing it as a fraction of the entire projected rotation of the whisker, so that the brain is continually updated on the way that the whisker’s rotation is being followed through.

Jun 01, 2012... Tiny particles such as atoms and electrons often behave in mysterious and surprising ways. Unlike larger objects composed of many particles, they can, for instance,exist simultaneously in more than one state. “According to the laws of quantum mechanics, a single atom can be in multiple locations at the same time and can be doing different things at the same time. We physicists call this the superposition principle,” says Dr. Roee Ozeri of the Weizmann Institute of Science’s Department of Physics of Complex Systems.
Aug 28, 2019... Did you know that malaria kills about half a million people each year? In the eighth episode of Weizmann in Focus, CEO Dave Doneson explains how Weizmann is helping to fight this terrible disease. Using computer-based tools, PhD student Adi Goldenzweig developed a groundbreaking malaria vaccine in the lab of Dr. Sarel Fleishman. Because the vaccine is inexpensive to produce and does not require refrigeration, it has the potential to help millions of people in developing countries where the battle against malaria is particularly devastating.
