The setup of lasers and mirrors effectively “solved” a problem far too complicated for even the largest traditional computer system.
For the first time, a quantum computer made from photons—particles of light—has outperformed even the fastest classical supercomputers.
Physicists led by Chao-Yang Lu and Jian-Wei Pan of the University of Science and Technology of China (USTC) in Shanghai performed a technique called Gaussian boson sampling with their quantum computer, named Jiŭzhāng. The result, reported in the journal Science, was 76 detected photons—far above and beyond the previous record of five detected photons and the capabilities of classical supercomputers. Read More

IBM Cloud gets quantum-resistant cryptography
IBM Corp. is looking to make enterprise workloads deployed on its public cloud resistant to tomorrow’s encryption-breaking quantum computers.
As a first step to that end, the company today introduced “quantum-safe cryptography” capabilities for three services in IBM Cloud: Red Hat OpenShift on IBM Cloud, Cloud Kubernetes Service and Key Protect. Customers using the services can now secure data with an encryption algorithm that will have a better chance of withstanding future quantum attacks, according to the company. Read More
Defending against the cryptographic risk posed by quantum computing
The nation must address a significant future threat in the potential adversarial development and deployment of a quantum computer—a machine that extends the usual rules of computation via quantum physics. Such a deployment would potentially have grave impacts on the security of the United States and its citizens if the proper technical mitigations are not put in place. Now is the time to prepare—in four ways highlighted below—for the complex transition to post-quantum algorithms well before the advent of a quantum computer. Read More
CCNY team in quantum algorithm breakthrough
Researchers led by City College of New York physicist Pouyan Ghaemi report the development of a quantum algorithm with the potential to study a class of many-electron quantums system using quantum computers. Their paper, entitled “Creating and Manipulating a Laughlin-Type ν=1/3 Fractional Quantum Hall State on a Quantum Computer with Linear Depth Circuits,” appears in the December issue of PRX Quantum, a journal of the American Physical Society.

Computer Scientists Achieve ‘Crown Jewel’ of Cryptography
A cryptographic master tool called indistinguishability obfuscation has for years seemed too good to be true. Three researchers have figured out that it can work.
… Indistinguishability obfuscation, if it could be built, would be able to hide not just collections of data but the inner workings of a computer program itself, creating a sort of cryptographic master tool from which nearly every other cryptographic protocol could be built. Read More
Threat of Quantum Computing to Bitcoin Should be Taken Seriously, But there’s Enough Time to Upgrade
LocalBitcoins, a leading peer to peer (P2P) Bitcoin exchange, notes that with the advent of quantum computing, there have been concerns that this new technology could be a threat to existing online protocols. Some experts claim that powerful quantum computers might become a legitimate threat to the security of Bitcoin (BTC) and the current encryption algorithms that it uses.
According to LocalBitcoins:
“While the threat of quantum computing to Bitcoin is to be taken seriously, experts believe that Bitcoin [and other cryptocurrencies] have time to adapt to the quantum age without compromising [their] security in the process.” Read More
How Can AI And Quantum Computers Work Together?
Traditional computers operate based on data that is encoded in a binary system. Essentially, each bit of data is represented in zeroes and ones only — no more, no less than the two forms. Hence, the binary computing system. However, there is a new generation of computers emerging on the horizon called quantum computing and it’s taking computing systems beyond the normal binary.
… One of the areas where quantum computing is more lucrative and promising is artificial intelligence. As AI operates on the analysis of large datasets, the margin of error and inaccuracy in the process of learning has significant room for improvement — and quantum computing may well allow us to improve the algorithm’s ability to learn and interpret.

Quantum leap for speed limit bounds
Google runs largest chemistry calculation on quantum computer
Google has successfully performed the largest chemical simulation on a quantum computer to date, a feat that can unlock new frontiers in chemistry, improving a wide variety of industries.
The Google AI Quantum team used a noise-robust variational quantum eigensolver (VQE) to directly simulate a chemical mechanism via a quantum algorithm. Read More
A new approach to quantum information processing at room temperatures
Researchers propose novel nanochips from atomically thin materials to make quantum computing possible
In October 2019, Google announced that their quantum processor achieved a computation in 200 seconds, which they claim would take even the most advanced supercomputers today approximately 10,000 years. While IBM has challenged this claim, such drastic changes in computational capabilities are indeed possible due to a fundamentally new technology called quantum computers. Read More
