I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#New evidence that the quantum world is even stranger than we thought” Experimental evidence of quasiparticles called anyons has been found by a team of scientists at Purdue University. Electrical interference in the experiment created a pattern which the researchers called a “pyjama plot”; jumps in the interference pattern were the signature of the presence…
“#New technology lets quantum bits hold information for 10,000 times longer than previous record” New Technology Lets Quantum Bits Hold Information for 10,000 Times Longer than Previous Record. Credit: Tohoku University Quantum bits, or qubits, can hold quantum information much longer now thanks to efforts by an international research team. The researchers have increased the…
“#Extracting order from a quantum measurement finally shown experimentally” A thin silicon nitride membrane (white) is stretched tight across a silicon frame (red). The membrane contains a pattern of holes, with one small island in the center, whose vibrations are measured in the experiment. Credit: Niels Bohr Institute In physics, it is essential to be…
“#Physicists nudge atoms within less than a trillionth of a second” The tip of an ultrafast scanning tunneling microscope (top-left) hovers over a molecular switch (bottom, connected red and black spheres). Ultrafast atomic forces (shock waves) induce vigorous motion of a select atom (red sphere) of the molecule to control its reactivity on ultrafast time…
“#Revolutionary quantum breakthrough paves way for safer online communication” The network in operation. The figure shows the receiving hardware for all 8 users. Credit: Siddarth K. Joshi The world is one step closer to having a totally secure internet and an answer to the growing threat of cyber-attacks, thanks to a team of international scientists…
“#A molecular approach to quantum computing” In a new theoretical study, Caltech physicists have shown how molecules can, in theory, be used to reduce errors in quantum computing. This strategy would involve placing a rotating molecule in “superposition,” which means that it would exist in multiple orientations at once. In this illustration, three different molecular…
“#Researchers manipulate two bits in one atom” Artist’s impression of the atom studied under the needle of a tunnel microscope. The spin and orbital angular momentum are indicated by a small and a large arrow respectively. Credit: TU Delft Researchers at Delft University of Technology have succeeded in independently manipulating two different types of magnetism…
“#New theory hints at more efficient way to develop quantum algorithms” Sabre Kais’ research group at Purdue is developing quantum algorithms and quantum machine learning methods. Credit: Purdue University In 2019, Google claimed it was the first to demonstrate a quantum computer performing a calculation beyond the abilities of today’s most powerful supercomputers. But most…
“#Google conducts largest chemical simulation on a quantum computer to date” Google’s Sycamore processor mounted in a cryostat, recently used to demonstrate quantum supremacy and the largest quantum chemistry simulation on a quantum computer. Credit: Rocco Ceselin A team of researchers with Google’s AI Quantum team (working with unspecified collaborators) has conducted the largest chemical…
“#Army scientists take new spin on quantum research” Credit: The Army Research Laboratory Army researchers discovered a way to further enhance quantum systems to provide soldiers with more reliable and secure capabilities on the battlefield. Specifically, this research informs how future quantum networks will be designed to deal with the effects of noise and decoherence,…
