Highlights

Geometry Labs have been awarded a grant regarding: Fusion signatures submission package for NIST standardization

Geometry Labs has developed highly aggregatable Fusion digital signatures for the QRL ecosystem with funding from the QRL Foundation’s grants programme.

Lattice cryptography, which provides post-quantum security, is the foundation for these very secure signatures. Fusion signatures were developed specifically for use in proof-of-stake systems that involve a large number of validators. The approach taken offers several benefits, including the simplification of the architecture, an increase in capacity, and smaller signatures and keys.

A formal specification and parameterization of the Fusion signature scheme is currently being developed by Geometry Labs; once complete, these algorithms will be made available to the public as open source software and shared with NIST for consideration as a possible standard.

To learn more, read our Fusion grant announcement blog and if you have any questions, you’ll want to get them prepared and stay tuned for an upcoming AMA!

Neven’s Law Explained - What It Means for the Future of Quantum Computing

We examine Moore’s Law, Neven’s Law, and the implications for quantum computing in our most recent episode.

Nevin’s Law has the potential to transform our perception of technology. It asserts that the processing capacity of quantum computers is increasing twice exponentially, i.e., the computer’s processing capability doubles for every additional qubit as the number of qubits increases. Neven’s Law has far-reaching implications since it predicts that in terms of processing power, quantum computers would eventually beat even the most powerful classical computers.

Quantum News

Nvidia positions for quantum computing with new products

On 2023-03-21: With new software and hardware, Nvidia Corp (NVDA.O), which powers most AI, is positioning itself as a quantum computing leader. Nvidia unveiled CUDA Quantum, a platform for building quantum algorithms in C++ and python, at GTC on Tuesday. The programme would run the algorithm on quantum and classical computers to find the most efficient solution. Nvidia's DGX Quantum hardware system connects quantum and classical computers. It is unclear when quantum computers could perform some calculations millions of times faster than the fastest supercomputer. Researchers can create hybrid applications and crucial quantum computing methods with DGX Quantum. - reuters

Japan quantum computer debut sets off scramble for tech breakthroughs

On 2023-03-28: Riken's first homegrown quantum computer could transform auto, finance, chemical, and pharmaceutical industries. The government and Riken plan to connect an over-100-qubit quantum computer to the Fugaku supercomputer in fiscal 2025. Fujitsu plans to finish a 64-qubit quantum computer in fiscal 2023 and 1,000 in 2026. Fujitsu will collaborate with Fujifilm and Tokyo Electron, while Riken will research Japanese businesses and universities.

Quantum computing may help develop new materials like electric-vehicle batteries and artificial photosynthesis. In 2022, NEC started using quasi-quantum technology to plan parts deliveries, hoping to earn 10 billion yen ($76 million) from optimisation services by 2025. - nikkei

UK to invest £2.5bn in quantum computing drive

On 2023-03-13: The UK government is investing £2.5bn in quantum computing to keep the UK competitive in one of the world's fastest-moving fields. The National Quantum Computing Centre will play a leading role in the expanded programme. The UK has the most quantum start-ups in Europe, with a new government programme to boost homegrown companies and address the shortage of qualified workers. - ft
