Experiment reverses the direction of heat flow - and time

Schematic of the experimental setup. a Heat flows from the hot to the cold spin (at thermal contact) when both are initially uncorrelated. This corresponds to standard thermodynamic. For initially quantum-correlated spins, heat is spontaneously transf…

New Developed Fiber is as Flexible as Elastic But Tough as Steel

Metal-rubber composite Researchers have developed a fiber that combines the elasticity of rubber with the strength of a metal. The resulting composite is a sturdier material that can be incorporated into lightweight robotics, p…

Cold fusion experiment fails, but Google will keep trying

Almost exactly 30 years ago, chemists Martin Fleischmann and Stanley Pons of the University of Utah in the United States gained instant worldwide fame by announcing that they had detected evidence of cold fusion. The fusion of atomic nucle…

Quantum Teleportation Moves Entire Logic Operation

Teleportation The quantum transporter transfers data of a quantum system (such as an ion) to another (one second ion), even though the two are completely isolated from each other. In this form of real-life teleportation, only qu…

Molecular assembler creates perfect Qubit

Molecular Assembler Last month, a New Zealand team was able, for the first time, to put two individual atoms to interact "gently" without colliding and without forcing the bar so they could react. Now a similar technique has been u…

Transistor saves 4 bits and bridges with quantum computing

Transistor that stores 4 bits Engineers at the University of Texas, USA, have created a multivalued transistor, that is, a transistor that can hold more values ​​than the traditional 0 and 1. With the difficulty of further miniaturizing tran…
