The team implemented the 'phase estimation algorithm' – a central quantum algorithm which achieves an exponential speedup over all classical algorithms. It lies at the heart of quantum computing and is a key sub-routine of many other important quantum algorithms, such as Shor's factoring algorithm and quantum simulations. Dr Xiao-Qi Zhou, who led the project, said: "Before our experiment, there had been several demonstrations of quantum algorithms, however, none of them implemented...

Playing Quantum Tricks By Reversing Measurements
2013-02-15 14:02:48

University of Innsbruck A team of physicists at the University of Innsbruck, Austria, performed an experiment that seems to contradict the foundations of quantum theory — at first glance. The team led by Rainer Blatt reversed a quantum measurement in a prototype quantum information processor. The experiment is enabled by a technique that has been developed for quantum error correction in a future quantum computer. Measurements on quantum systems have puzzled generations of...

Recycling In The Quantum World Could Lead To Better Teleportation

Alan McStravick for redOrbit.com - Your Universe Online What Einstein once referred to as “spooky action at a distance” could be our way into a 'Star Trek' future Watching the original 'Star Trek' series as a child, the most enthralling part of any episode was the moment they dissolved during teleportation on their way down to an alien planet. The science behind that at-one-time fiction shows it is now en route to becoming fact. The possibility of teleportation was first...

Speeding Up Data Compression Algorithms
2012-11-13 21:06:04

Lee Rannals for redOrbit.com — Your Universe Online A new way of representing data might open up new possibilities for Internet-connected sensors like GPS receivers and cameras in smartphones. Computer scientists are running into problems as more devices become Internet connected. An explosion of data needs more-efficient algorithms to handle the load, and MIT researchers have found a new way to represent data that takes up much less space in memory but can still be processed in...

Griffith Uni researchers lead light breakthrough Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise. The research collaboration, involving Griffith University, The University of Queensland and University of Science and Technology of China, was able to amplify the noisy quantum state of a single photon subjected to loss, without adding noise in the process; in fact, their amplification reduced...

Algorithm
2013-12-16 10:46:30

In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculations, automated reasoning, and data processing. An algorithm is an effective technique expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial state and an initial input, the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states and eventually...
