USC to Lead IARPA Quantum Computing Project

USC will lead a consortium of universities and private companies to build quantum computers that are at least 10,000 times faster than the best state-of-the-art classical computers.Such high-powered machines could help facilitate the solution of some of the most difficult optimization problems such as machine learning for image recognition, resolving scheduling conflicts in events with many participants, as well as sampling for improved prediction of random events.

Shaking Schrödinger's cat

Frequent measurement of a quantum system's state can either speed or delay its collapse, effects called the quantum Zeno and quantum anti-Zeno effect. But so too can "quasimeasurements" that only poke the system and garner no information about its state.

How to Reduce Shockwaves in Quantum Beam Experiments

narevicius_skimmerexperiment4.jpg

Weizmann Institute of Science researchers used aeronautical engineering to devise a simple method of reducing shockwaves and brightening beams. The method was inspired by the similarity of the “skimmers” used in physics experiments to the air intake mechanisms on air and spacecraft.

Random Numbers: Hard Times Ahead for Hackers

415ebb11038c0dae13f2e0261fe3bcf9_f605.jpg

Whenever we need to communicate in secret, a cryptographic key is needed. For this key to work, it must consist of numbers chosen at random without any structure – just the opposite of using the birthdate of our favourite pet. But, for a human, it is extremely difficult to choose without creating any bias, even by hitting the keyboard chaotically. To solve this problem, researchers from the University of Geneva (UNIGE), Switzerland, have developed a new random numbers generator based on the principles of quantum physics.

Advanced quantum dots shed bright light on biological processes

Precise fluorescent imaging at the molecular level has not been possible because of non-specific fluorescence by surrounding tissues. Now researchers have resolved many of these problems by using SWIR quantum dots in live mice to image working organs, take metabolic measurements, and track microvascular blood flow in normal brain and brain tumors

Quantum Mechanics Is Complex Enough, for Now…

Walther_Nature_park.jpg

Physicists have searched for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. To do so a research team led by Philip Walther at the University of Vienna designed a new photonic experiment using exotic metamaterials, which were fabricated at the University of California Berkeley. Their experiment supports standard quantum mechanics and allows the scientists to place bounds on alternative quantum theories. The results, which are published in "Nature Communications", could help to guide theoretical work in a search for a more general version of quantum mechanics.
