Wireless quantum encryption
The technique is based on characteristics of individual photons that are generated randomly between the sender and the receiver. Although researchers have already transmitted quantum encryption keys t...
Field theorists win Dirac prize
The citation highlights Adler’s derivation of a sum rule for pion-nucleon scattering that marked a breakthrough in our understanding of the currents and broken symmetries of the strong interacti...
Talking physics with the Dalai Lama
Zeilinger had invited the Dalai Lama to his laboratory following a meeting at Dharamsala in Northern India last October at which he and four other physicists had, over the course of five days, discuss...
Light makes insulator conduct
The researchers cooled the manganese oxide compound (Pr0.7Ca0.3MnO3) to below 200 K in a zero magnetic field. At this temperature the electrons drop into a low energy state, which minimizes their natu...
Shuttle goes on ‘antimatter’ hunt
The known universe consists almost entirely of matter. However, it is thought that equal amounts of matter and antimatter were created during the big bang. One possibility is that this antimatter now ...
Quantum computers shape up
The two recent breakthroughs exploit the quantum properties of nuclear spins, which can point “up” or “down” relative to an applied electric or magnetic field. A team of physic...
Physicist shares Japan Prize
Leo Esaki, the physicist who is president of the University of Tsukuba, is one of the joint winners of this year's Japan Prize
Fermion first for quantum interference
Bosons (for example, photons) cause constructive interference patterns. This means that the probability that both particles are detected in the same direction is enhanced by the intereference. On the ...
Aharonov and Berry share Wolf Prize
The 1998 Wolf Prize has been awarded to Yakir Aharonov and Sir Michael Berry
