COMPUTERS May 19, 2020 Quantum Computers Challenge Blockchain’s Invincibility: What To Do Now
By: Loknath DasTimelines for the emergence of quantum computers may be fuzzy, but the threat they pose to the vaunted security of blockchain technology is profoundly real. Originally popular as fail-safe security for bitcoin enthusiasts, blockchain is making inroads across numerous industries, most notably as a track and trace tool proving the provenance of goods across vast […]

ELECTRONICS December 11, 2019 Scientists Just Created Quantum States in Everyday Electronics
By: Loknath DasQuantum computing has the potential to revolutionise the processing power at our fingertips, but for the moment a lot of it is just potential. Researchers have been uncertain on whether we’ll ever be able to harness quantum computing in a practical, affordable, realistic way. But we might have an exciting new lead. Two new studies show how quantum […]

COMPUTERS March 9, 2019 INSIDE THE HIGH-STAKES RACE TO MAKE QUANTUM COMPUTERS WORK
By: Loknath DasDEEP BENEATH THE Franco-Swiss border, the Large Hadron Collider is sleeping. But it won’t be quiet for long. Over the coming years, the world’s largest particle accelerator will be supercharged, increasing the number of proton collisions per second by a factor of two and a half. Once the work is complete in 2026, researchers hope to […]

COMPUTERS March 5, 2019 IBM’s quantum computing ambitions get exponential like Moore’s Law
By: Loknath DasQuantum computers are just weird, with data processed by qubits that can store ones and zeros at the same time. But they’re like regular “classical” computers in one obvious way: Their designers want them to run faster. Now, with machines like its Q System One, IBMhas not only proposed a convenient single number to calibrate a speedometer […]

COMPUTERS February 25, 2019 Why Quantum Computing’s Time Is Now
By: Loknath DasDEPOSITPHOTOS 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 promises to be a disruptive technology […]

COMPUTERS February 22, 2019 Calculating Quantum Computing’s Future
By: Loknath DasIn 1982, Nobel Prize–winning physicist Richard Feynman conceived of an ultrapowerful calculator that relies on microscopic particles to operate. He called his idea a “quantum” computer, referring to the laws that govern nature at a subatomic level. Today, some of the technology industry’s biggest companies, such as IBM, Google, Intel, Microsoft, and China’s Alibaba, have latched onto the idea. They, […]

October 28, 2018 Machine Learning and Big Data in the Quantum Computing Age
By: Loknath DasIn the information technology age, on an average 2.5 exabytes of data is produced every day, which is equivalent to the content of 5 million laptops. Humongous isn’t it? Here is more, on a daily basis, every minute 3.2 billion global internet users add massive data to the data banks with 347,222 Tweets, 4.2 million Facebook likes, 9,722 […]

COMPUTERS October 27, 2018 Understanding quantum computers: The noise problem
By: Loknath DasQuantum computers are fragile miracles of physics that are unreliable, cost-prohibitive, and more error-prone than a shortstop with no depth perception. But, if we ever want to get to Star Trek levels of technology, we probably need them. To make them useful we have to make them reliable. And that’s a pretty tall order. The […]

COMPUTERS October 26, 2018 Opinion | Catch a quantum computer and pin it down
By: Loknath DasUrmila Mahadev has a soft voice with slightly nasal inflections, rounding out what we in India would have no hesitation in describing as a “generic American accent”. With gadgets in each hand controlling her presentation and her microphone, she speaks for an hour and she speaks in English and yet I fully grasp only parts […]

ELECTRONICS December 2, 2017 New High-Speed Quantum Encryption Could Thwart Hackers: Study
By: Loknath DasScientists have developed a high-speed encryption system that can protect against the common security attacks, even if the equipment has flaws that could make it vulnerable to leaks. The system is capable of distributing encryption codes at megabit-per-second rates, five to 10 times faster than existing methods and on par with current Internet speeds when […]

COMPUTERS November 21, 2017 The Future of Bitcoin is Threatened by Quantum Computers
By: Loknath DasA Different Kind of Computing While much of the world is captivated by the meteoric rise of bitcoin’s value, others are focused on the technology behind the cryptocurrency: blockchain. The decentralized digital ledger tech is built upon a peer-to-peer network, and it is far more secure than the centralized systems used by traditional banks and financial […]

COMPUTERS November 14, 2017 IBM announces new advanced quantum computers
By: Loknath DasIBM has announced hitting a big milestone in the ongoing race of building the most powerful quantum computer. Dario Gil, who leads IBM’s quantum computing and artificial intelligence research division, said last week that the company’s scientists have successfully built and measured a processor prototype with 50 quantum bits, known as qubits. Gil says it’s […]
