Imagine you’re the star of an action movie about a kidnapping. As part of the story, you come into hold of a secret message, which says where the victim is hidden. Unfortunately, the message is encrypted using a 12-digit secret key, a string of digits such as 8409. But you don’t know the hidden key.
A simple manner is to search through all the possible routes, while keeping track of the minimal route found. Of course, it’s possible to flourish more sophisticated algorithms for TSP, algorithms that make it unnecessary to search through every route. Indeed, search is sometimes a good final-cut approach. Overall, search is an exceptionally useful general-purpose algorithm.
Finder has just publish an interview with Ethereum core analyst Danny Ryan, who is spearheading Ethereum 2.0 and the move to Proof of Stake.
In the meeting with host Fred Schebesta, Ryan says Ethereum wants to be quantum resistant within three to five years and that he expects Ethereum 2.0 to be live by the end of 2019, or the start of 2020. New test nets are scheduled to go live in the next quarter.
Appearing at EDCON, the Ethereum developers’ conference, which just wrapped up in Sydney, Australia on April 13, Ryan joined the Ethereum Foundation members for a Q&A panel with Finder.
Four stories underground — confined in several feet of concrete — is the University of Chicago’s new nanofabrication facility, where researchers enact the principles of quantum physics to real-world problems and technologies.
A little cadre of faculty and graduate students in a clean room bathed in yellow light wear protective clothing to ensure the probity of the experiments they are conducting, which involves the very matter that comprise the universe: electrons, photons, neutrons and protons.
Programmers are human, but mathematics is perpetual. By making programming more mathematical, a group of computer scientists is hoping to terminating the coding bugs that can open doors to hackers, spill digital secrets and generally plague modern society.
Now a set of computer scientists has taken a vital step toward this goal with the release today of EverCrypt, a set of digital cryptography tools.
The Department of Energy presented plans Tuesday to make $40 million in allotment funding available to multidisciplinary teams developing advanced algorithms and software for quantum computers.
Since 2014, DOE’s Office of Science has estimated and invested in early quantum simulations, machine-learning algorithms and software stacks. The supercomputers are expected to transform work in the fields of quantum physics, chemistry and biology.
Forget Rodeo Drive, Fifth Avenue, or Regent Street—Balogun Market in Lagos truly is the shopping metropolis of the world. Its crammed, umbrella-shielded corrugated metal stalls is abuzz with trades and transactions. Hundreds more shops, wholesalers, and cramped workshops fill the honeycombed concrete buildings that ring the market.
Balogun Market is in many ways a little world of Nigeria: a country known globally as a petro-economy, but one that in reality is a country of small business people. Nigeria’s entrepreneurs generally power Africa’s largest economy, generating almost 50% of its GDP and employing 60 million people—roughly 84% of its labor force.
Erica Grant bears the key to rectifying a security flaw that puts thousands of hotels – and their guests – at risk each year.
With as much enthusiasm for security as she has for quantum computing, Grant, 24, has unlocked a way to guard doors against tech-savvy intruders.
Her perception sets out to fix one big problem: It’s viable– easy, even – to get an old key card from a hotel and convert it into a master key that can access any room in the building, said Grant, a Virginia native now pursuing her doctorate through the Bredesen Center for Interdisciplinary Research and Graduate Education at the University of Tennessee.
Komodo is delighted to declare the incorporation of Dilithium, a quantum-secure digital signature scheme. This new technology yield protection against attacks from quantum computers, ensuring an unparalleled level of security.
While adopting a quantum-secure cryptographic signature scheme would normally be the only focus of an entire blockchain project— perhaps with its own coin, an ICO, and a dedicated team of developers— the power of Komodo’s technology allowed jl777 to complete the task in just a few days.
A new technique allows the quantum state of atomic “qubits”— the basic unit of data in quantum computers — to be measured with twenty times less error than was previously feasible, without losing any atoms. Precisely measuring qubit states, which are equivalent to the one or zero states of bits in traditional computing, is a vital step in the development of quantum computers.
We are working to develop a quantum computer that uses a three-dimensional array of laser-cooled and trapped cesium atoms as qubits,” said David Weiss, professor of physics at Penn State and the leader of the research team.
