The Holy Grail of quantum cryptography – beyond delivering security that cannot be classically achieved – is guaranteeing unconditional security when the untrusted quantum devices are involved. While this goal has been ...
(Â鶹ÒùÔº) —Within the mammalian inner ear, or cochlea, a remarkable but and long-debated phenomenon occurs: As they move from the base of the cochlea to its apex, traveling fluid waves – that is, surface waves, in which ...
(Â鶹ÒùÔº) —While quantum states are typically referred to as particles or waves, this is not actually the case. Rather, quantum states have complementary discrete particlelike and continuous wavelike properties that emerge ...
Quantum mechanics is about to fundamentally change the way we can transmit and sense information. The idea is that information—represented by physical quantities such as the spin or the polarisation of an individual photon—can ...
(Â鶹ÒùÔº) —When C. K. Hong, Z. Y. Ou and Leonard Mandel demonstrated destructive quantum interference between pairs of indistinguishable bosons in their 1987 paper1, they did so with massless photons. Their protocol – ...
Computing experts at Sandia National Laboratories have launched an effort to help discover what computers of the future might look like, from next-generation supercomputers to systems that learn on their own—new machines ...
Michael Lewis's bestselling book "Flash Boys" describes how some brokers, engaging in high frequency trading, exploit fast telecommunications to gain fraction-of-a-second advantage in the buying and selling of stocks. But ...
Our Sun may seem pretty impressive: 330,000 times as massive as Earth, it accounts for 99.86 percent of the Solar System's total mass; it generates about 400 trillion trillion watts of power per second; and it has a surface ...
A white Lexus cruised along a road near the Google campus, braking for pedestrians and scooting over in its lane to give bicyclists ample space.
Until recently measuring a 27-dimensional quantum state would have been a time-consuming, multistage process using a technique called quantum tomography, which is similar to creating a 3D image from many 2D ones. Researchers ...
