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 ...
The concept of a perpetual motion machine is an enticing one: Imagine a machine that runs continuously without requiring any external energy—a feat that could make refueling vehicles a thing of the past.
(Â鶹ÒùÔº) —Australian National University PhD student Seiji Armstrong has made a quantum leap towards next-generation computing.
In the unending effort to reduce the size of computing nodes, scientists at University of Liège, Belgium, The Hebrew University, Jerusalem, University of Padova, Italy, and University of California, Los Angeles have employed ...
(Â鶹ÒùÔº) —To get a better understanding of the subatomic soup that filled the early universe, and how it "froze out" to form the atoms of today's world, scientists are taking a closer look at the nuclear phase diagram. ...
(Â鶹ÒùÔº) —A research team composed of members from China, Singapore and Canada has built a simple quantum computer that has proven a quantum algorithm developed in 2009. In their paper published in Â鶹ÒùÔºical Review Letters, ...
(Â鶹ÒùÔº) —Throughout the '70s, '80s and '90s, transistor performance continually increased according to some simple scaling rules. These rules postulate that transistor size and supply voltage should decrease as power ...
(Â鶹ÒùÔº) —There is, so to speak, uncertainty about uncertainty – that is, over the interpretation of how Heisenberg's uncertainty principle describes the extent of disturbance to one observable when measuring another. ...
(Â鶹ÒùÔº)—The presence of quantum coherence in photosynthesis in plants, bacteria and marine algae at ambient temperatures is well-established. Two such effects that appeared to be unrelated – enhanced solar cell efficiency ...
