Amazon Introduces New Quantum Chip To Reduce Errors

Posted by in categories: computing, quantum physics

Quantum computing, the cutting-edge technology that promises unprecedented computational power, has taken a significant leap forward with the unveiling of a groundbreaking quantum chip by Amazon Web Services.

“It’s a custom-designed chip that’s totally fabricated in house by our AWS quantum team,” said Peter Desantis, senior vice president of AWS utility computing products, during a keynote address in Las Vegas at AWS’s re: Invent conference for the global cloud computing community.

DeSantis said the state-of-the-art chip represents a major milestone in the quest for error-corrected quantum computers. “We’ve been able to suppress errors by 100x by using a passive error correction approach,” he said.

Analyst Panel Says Take the Quantum Computing Plunge Now…

Posted by in categories: quantum physics, robotics/AI

Should you start exploring quantum computing? Yes, said a panel of analysts convened at Tabor Communications HPC and AI on Wall Street conference earlier this year.

Without doubt, the quantum computing landscape remains murky. Yet in the past ~5 years virtually every aspect of quantum computing has raced forward. At least one 1000-plus-qubit system is edging towards user access now and another is expected by year-end. There’s been a proliferation of software offerings up and down the “quantum stack” though it’s hardly complete. Most promising, what were a few POC use-case explorations has mushroomed into very many efforts across many sectors.

What are we waiting for? Against the backdrop of astonishing progress are also very hard technical problems. Error correction/mitigation tops the list. Effective quantum networking is another. Polished applications. Too many qubit types to choose from (at least for now.) Scale matters – it’s expected that millions of qubits may be needed for practical quantum computing These aren’t trivial challenges. Why bother?

Investigating and fine-tuning the properties of ‘magic’ graphene

Posted by in categories: energy, quantum physics

Recent advances in the development of devices made of 2D materials are paving the way for new technological capabilities, especially in the field of quantum technology. So far, however, little research has been carried out into energy losses in strongly interacting systems.

With this in mind, the team led by Professor Ernst Meyer from the Department of Physics at the University of Basel used an in pendulum mode to investigate a device in greater detail. For this, the researchers utilized a two-layer graphene, fabricated by colleagues at LMU Munich, in which the two layers were twisted by 1.08°

When stacked and twisted relative to one another, the two layers of graphene produce “moiré” superstructures, and the material acquires new properties. For example, when the two layers are twisted by the so-called magic angle of 1.08°, graphene becomes a superconductor at very low temperatures, conducting electricity with almost no energy dissipation.

‘First Ever’ Experiments to Measure Theoretical ‘Quantum Flickering’ in an Empty Vacuum Slated for 2024

Posted by in categories: particle physics, quantum physics

German researchers hoping to be the first to successfully measure quantum flickering directly in a completely empty vacuum are setting their sights on 2024.

If successful, the first-of-their-kind experiments are expected to either confirm the existence of quantum energy in the vacuum, a core concept of quantum electrodynamics (QED), or potentially result in the discovery of previously unknown laws of nature.

Researchers achieve zero-knowledge proof based on device-independent quantum random number beacon

Posted by in categories: blockchains, encryption, information science, quantum physics, security

Zero-knowledge proof (ZKP) is a cryptographic tool that allows for the verification of validity between mutually untrusted parties without disclosing additional information. Non-interactive zero-knowledge proof (NIZKP) is a variant of ZKP with the feature of not requiring multiple information exchanges. Therefore, NIZKP is widely used in the fields of digital signature, blockchain, and identity authentication.

Since it is difficult to implement a true random number generator, deterministic pseudorandom number algorithms are often used as a substitute. However, this method has potential security vulnerabilities. Therefore, how to obtain true random numbers has become the key to improving the security of NIZKP.

In a study published in PNAS, a research team led by Prof. Pan Jianwei and Prof. Zhang Qiang from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, and the collaborators, realized a set of random number beacon public services with device-independent quantum as entropy sources and post-quantum cryptography as identity authentication.
