Google has developed a quantum computing chip that can easily outpace the modern supercomputers. Describing the feat as “Quantum Supremacy”, Google says its new chip performed a target computation in 200 seconds which the world’s fastest super computer would have taken 10,000 years to produce a similar output. Google CEO Sundar Pichai described the new chip as a “big breakthrough.”
Google’s ‘Quantum Supremacy’ was first reported by Financial Times last month. The company on Wednesday published its official study in Nature along with a detailed blog post. Google disclosed that it had developed a new 54-qubit processor, known as “Sycamore.”
“The quantum supremacy experiment was run on a fully programmable 54-qubit processor named “Sycamore.” It’s comprised of a two-dimensional grid where each qubit is connected to four other qubits. As a consequence, the chip has enough connectivity that the qubit states quickly interact throughout the entire processor, making the overall state impossible to emulate efficiently with a classical computer,” John Martinis, Chief Scientist Quantum Hardware and Sergio Boixo, Chief Scientist Quantum Computing Theory, Google AI Quantum explained in a blog post.
“The success of the quantum supremacy experiment was due to our improved two-qubit gates with enhanced parallelism that reliably achieve record performance, even when operating many gates simultaneously. We achieved this performance using a new type of control knob that is able to turn off interactions between neighboring qubits. This greatly reduces the errors in such a multi-connected qubit system. We made further performance gains by optimizing the chip design to lower crosstalk, and by developing new control calibrations that avoid qubit defects,” they added.
After having achieved quantum supremacy, Google researchers are now looking at its applications which range from machine learning, quantum chemistry to quantum physics. Going forward, the team will make its quantum processors available to more researchers and firms interested in developing relevant algorithms.

Google’s latest feat is going to revive interest in the quantum computing field. Already, technology companies such as Microsoft and IBM are working towards building quantum computers.
IBM has already showcased its early versions of a functional quantum computer. Microsoft is also taking various initiatives to democratise quantum computing. Earlier this year, Microsoft open sourced Q# programming to push quantum computing.
“Quantum is an exciting new frontier for developers. Microsoft designed Q# specifically for quantum programming, delivering an approachable, high-level programming language with a native-type system for qubits, operators and other abstractions,” Microsoft said in a release earlier this year.
Not so fast?
The quest for quantum supremacy is still far from over, however. The authors themselves acknowledge the need for better hardware and more sophisticated monitoring techniques in order to truly harness the power of quantum.
Some immediate applications of quantum computing could be in encryption software and AI, but its calculations could eventually lead to more efficient solar panels, drug design and even quicker and better financial transactions.
Wednesday’s announcement was not without controversy.
After a leaked draft of the Google lab’s paper appeared online last month, chip-maker IBM, which runs its own quantum computing programme, said the boasts of the Sycamore computer’s feats were exaggerated.
Instead of 10,000 years for an ordinary supercomputer to match Sycamore’s performance, IBM scientists in a blog post claimed it would be more like two-and-a-half years using the most sophisticated traditional processors.
“Because the original meaning of the term ‘quantum supremacy’… was to describe the point where quantum computers can do things that classical computers can’t, this threshold has not been met,” they wrote.
Govt blocks several social media handles circulating fake, inciting content
In the midst of the enormous lockdown on contemptuous posts, sources said that the hostile substance actioned related to the counterfeit video of a cupboard instructions, an enlivened phony video showing viciousness against the Prime Minister, and disparaging posts focusing on Hindu ladies transferred via web-based media handles.
The public authority has hindered a few web-based media handles that were coursing “counterfeit and affecting” content on Twitter, YouTube, and Facebook, Minister of State for IT Minister Rajeev Chandrasekhar said on Saturday.
Proprietors of these records are being recognized for activity under the law, he added.
“Taskforce on Safe and Trusted Internet at @GoI_MeitY at work. Handles that attempted to push counterfeit/inducing content on twitter, youtube, fb, insta have been impeded,” Chandrasekhar Tweeted on Saturday.
The pastor said proprietors of such records are being distinguished for activity under the law, and declared that stages will be investigated on their due steadiness.
On Friday evening, the pastor had reacted to a tweet that encouraged him to make a move against the “makers of an exceptionally fierce video that includes the PM”, which “has been in the public area since December 2020”.
PhonePe will now charge upto Rs 2 per transaction for mobile recharges
Walmart-owned digital payments app PhonePe will now charge processing fees for every transaction. This means that you will no longer be able to transfer money or recharge your phone without shelling out a little extra money for every transaction. The company has said that it would charge fees in the range of Re 1 to Rs 2 per transaction for mobile recharges for value above Rs 50. PhonePe is the first payments’ app to have started charging for UPI-based transactions
“On recharges, we are running a very small-scale experiment where a few users are paying for mobile recharges. Recharges below Rs 50 are not charged, recharges between Rs 50 and Rs 100 are charged Re 1 and above Rs 100 are charged Rs 2. Essentially, as a part of the experiment, a majority of users are either not paying anything or paying Re 1,” a PhonePe spokesperson told PTI.
PhonePe s charging processing fees for UPI-based transactions for value above Rs 50. If you don’t spend upto Rs 50, you will not be charged any amount by the digital app. Like other payments apps, PhonePe will also begin charging processing fees for payments made through credit cards. PhonePe is one of the most popular, widely-used payments app in India along with Paytm and Google Pay. It has recorded over 165-crore UPI transactions on its platform in September, clocking over 40 per cent share among the app segment, the PTI report stated.
“We are not the only player or payment platform charging a fee. Charging a small fee on bill payments is now a standard industry practice and is done by other biller websites and payment platforms also. We charge a processing fee (called a convenience fee on other platforms) on payments with credit cards only,” the spokesperson added.
For the unversed, just like Paytm and Google Pay, PhonePe can be used to transfer money with BHIM UPI, manage multiple bank accounts, check account balance, save beneficiaries across multiple bank accounts like SBI, HDFC, ICICI & 140+ banks. Recharge prepaid mobile numbers like Jio, Vodafone, Idea, Airtel etc, recharge DTH like Tata Sky, Airtel Direct, Sun Direct, Videocon etc, pay various bills and more. You can also buy or renew insurance policies using PhonePe.
