IBM reduces noise in quantum computing, increasing accuracy of calculations

By James Sanders on March 27, 2019 IBM researchers found a method to reduce noise in quantum computing by amplifying noise at measurable intervals, and extrapolating a difference to calculate a “zero-noise” result. In an effort to extend the computational ability of current-generation quantum computers, IBM announced Wednesday a method called “zero-noise extrapolation” that improves…

Machine learning is implemented on an IBM quantum processor

14 Mar 2019 by Hamish Johnston Machine-learning algorithms have been run on a quantum computer by physicists at IBM. Although the proof-of-concept demonstration did not involve practical tasks, the team hopes that scaling-up the algorithms to run on larger quantum systems could give machine learning a boost. Machine learning is a type of artificial intelligence…

Physicists reverse time using quantum computer

March 13, 2019, Moscow Institute of Physics and Technology Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space…

Securing the ‘internet of things’ in the quantum age

MARCH 4, 2019 by Rob Matheson, Massachusetts Institute of Technology MIT researchers have developed a novel cryptography circuit that can be used to protect low-power “internet of things” (IoT) devices in the coming age of quantum computing. Quantum computers can in principle execute calculations that today are practically impossible for classical computers. Bringing quantum computers…

Quantum computing: Testing qubits has been put in a faster lane

MARCH 3, 2019 by Nancy Cohen , Tech Xplore A way to speed up quantum computer tech progress has arrived from Intel. If you are interested in following the waves and advances in quantum computing, then get familiar with this word trio: Cryogenic Wafer Prober. Before their design, the electrical characterization of qubits was slower…

Explainer: What Is Quantum Communication?

MIT Technology Review on Feb 22, 2019 Researchers and companies are creating ultra-secure communication networks that could form the basis of a quantum internet. This is how it works. By Martin Giles Barely a week goes by without reports of some new mega-hack that’s exposed huge amounts of sensitive information, from people’s credit card details…

D-Wave announces its next-gen quantum computing platform

by Frederic Lardinois on 28 Feb 2019 D-Wave, the well-funded quantum computing company, today announced its next-gen quantum computing platform with 5,000 qubits, up from 2,000 in the company’s current system. The new platform will come to market in mid-2020. The company’s new so-called Pegasus topology connects every qubit to 15 other qubits, up from six in…

Physicists Just Achieved Quantum Teleportation Underwater For The First Time

on April 10, 2018 Chinese scientists have successfully sent information between entangled particles through sea water, the first time this type of quantum communication has been achieved underwater. In this proof-of-concept experiment, information was sent across a 3.3-metre (10.8-foot) long tank of seawater, but the researchers predict they should be able to use the same…

Why Quantum Computing’s Time Is Now

Feb 24, 2019 by Nella Ludlow DEPOSITPHOTOS ENHANCED BY COGWORLD Most technologists have some basic understanding of quantum computing.  Quantum bits are represented by qubits, and information isn’t simply a zero or one, it can be both at the same time, representing much more information.  A quantum effect known as entanglement linking two particles allows instantaneous communication.  Ultimately, quantum computing…
