November 9, 2017 Quantum computers could crack Bitcoin, but fixes are available now
An international group of quantum boffins reckons Bitcoin could be broken by the year 2027. The researchers from Singapore, Australia and France say that scenario represents the worst case, and would see a quantum computer able to run Shor’s algorithm against the cryptocurrency’s protective elliptic curve signature quicker than the 10 minutes Bitcoin needs to […]

November 9, 2017 Quantum Computers Pose Imminent Threat to Bitcoin Security
Bitcoin is taking the world by storm. The decentralized digital currency is a secure payment platform that anybody can use. It is free from government interference and operated by an open, peer-to-peer network. This independence is one reason Bitcoin has become so popular, causing its value to rise steeply. At the beginning of 2017, a single […]

October 23, 2017 Google Debuts Software to Open Up Quantum Computers for Chemists
Google unveiled software aimed at making it easier for scientists to use the quantum computers in a move designed to give a boost to the nascent industry. The software, which is open-source and free to use, could be used by chemists and material scientists to adapt algorithms and equations to run on quantum computers. It […]

October 12, 2017 Quantum Computing Will Change Everything, and Sooner Than You Expect
When we say an emerging technology represents a “paradigm shift,” it’s often hyperbole. In the case of quantum computers, it’s an understatement. In traditional computing—everything from PCs to ATMs to smartphones—all data is represented in bits that exist in one of two states: 0 or 1, off or on. In quantum computing, bits can be 0, […]

September 20, 2017 IBM Just Broke The Record of Simulating Chemistry With a Quantum Computer
The Future of Quantum Computing Engineers have modelled the interactions between subatomic components of a complex molecule using a quantum computer, making a significant leap forward in our modelling of chemical reactions. Image Source: Berkeley University The simulations were carried out by IBM on superconducting hardware, and this milestone just pushed into new territory for […]

September 8, 2017 This qubit redesign may make it easier to make quantum computers
Quantum computers could handle models that are too complex for us to run now Tomasz Zajda/Alamy Stock Photo The race to create superfast computers is accelerating. A rethink of one of the most fundamental parts of a quantum computer could pave the way for ultra-powerful devices. Andrea Morello at the University of New South Wales in […]

August 3, 2017 Exactly what could quantum computers do?
They picked a knotty problem – understanding how the enzyme nitrogenase allows plants to use nitrogen from the atmosphere to make their own fertilizer – something that is unknown. Computers available today, said EHT chemistry professor Markus Reiher can calculate the behaviour of simple molecules quite precisely, but not nitrogenase , which is too complex. […]

August 2, 2017 The Age of Quantum Computers is upon us!
The first electronic computer that was ever invented was the Turing Machine developed in 1936 which was a bulky device that had a size of a room and had very limited operations. By 1977 full-scale computers capable of complex computation and data processing started shipping in from companies including Apple and Commodore. In 1984 Mac […]

August 1, 2017 Quantum computing as the future? Here’s why it is still waiting for the hardware
The industry first has to solve hardware issues in quantum technology, according to an expert. (Representational Image.

July 10, 2017 Computers Are on the Verge of a Quantum Leap
Conceptual artwork representing how data may be controlled and stored in a quantum computer. ALFRED PASIEKA/SCIENCE PHOTO LIBRARY Moore’s Law is a computing term coined by co-founder of Intel Gordon Moore, who predicted the pace of the modern digital world would exponentially increase biannually. This predicted rapid growth of computers has remained constant over the past several decades, but […]

May 9, 2017 Nanofridge could keep quantum computers cool enough to calculate
Even quantum computers need to keep their cool. Now, researchers have built a tiny nanoscale refrigerator to keep qubits cold enough to function. Classical computers require built-in fans and other ways to dissipate heat, and quantum computers are no different. Instead of working with bits of information that can be either 0 or 1, as […]

April 21, 2017 New quantum liquid crystals may play role in future of computers
These images show light patterns generated by a rhenium-based crystal using a laser method called optical second-harmonic rotational anisotropy. At left, the pattern comes from the atomic lattice of the crystal. At right, the crystal has become a 3-D quantum liquid crystal, showing a drastic departure from the pattern due to the atomic lattice alone. […]
