A team of computer scientists and financial specialists at University College London has developed a tool to track the coordination efforts of pump-and-dump crypto coin scheme manipulators. They have published a paper on the arXiv preprint server describing their tool called Perseus, its purpose and how it works.

Researchers at QuTech, in collaboration with Fujitsu and Element Six, have demonstrated a complete set of quantum gates with error probabilities below 0.1%. While many challenges remain, being able to perform basic gate operations with errors occurring below this threshold, satisfies an important condition for future large-scale quantum computation. The research was published in Physical Review Applied on 21 March 2025.
Quantum computers are anticipated to be able to solve important problems that are beyond the capabilities of classical computers. Quantum computations are performed through a large sequence of basic operations, called quantum gates.
For a quantum computer to function, it is essential that all quantum gates are highly precise. The probability of an error during the gates must be below a threshold, typically of the order 0.1 to 1%. Only then, errors are rare enough for error correction methods to work successfully and ensure reliable computation with noisy components.
The University of Osaka, Fujitsu Limited, Systems Engineering Consultants Co., LTD. (SEC), and TIS Inc. (TIS) today announced the launch of an open-source operating system (OS) for quantum computers on GitHub, in what is one of the largest open-source initiatives of its kind globally. The Open Quantum Toolchain for Operators and Users (OQTOPUS) OS can be customized to meet individual user needs and is expected to help make practical quantum computing a reality.
Until now, universities and companies seeking to make their quantum computers accessible via the cloud have had to independently develop extensive software to enable cloud-based operation. By offering this open-source OS—covering everything from setup to operation—the research partners have lowered the barrier to deploying quantum computers in the cloud.
Additionally, quantum computing cloud service offered by the University of Osaka has begun integrating OQTOPUS into its operations and Fujitsu Limited will make it available for research partners using its quantum computers in the second half of 2025.
What happens when quantum computers can finally crack encryption and break into the world’s best-kept secrets? It’s called Q-Day—the worst holiday maybe ever.
For as long as we’ve been building computers, it feels like we’ve been speaking the same language — the language of bits. Think of bits as tiny switches, each stubbornly stuck in either an ‘on’ or ‘off’ position, representing the 1s and 0s that underpin everything digital. And for decades, refining these switches, making them smaller and faster, has been the name of the game. We’ve ridden the wave of Moore’s Law, achieving incredible feats of computation with this binary system. But what if, perhaps, we’ve been looking at computation in just black and white, when a whole spectrum of possibilities exists?
Bravyi, Dial, Gambetta, Gil, and Nazario from IBM Quantum in “The Future of Quantum Computing with Superconducting Qubits” say.
For the first time in history, we are seeing a branching point in computing paradigms with the emergence of quantum processing units (QPUs).
UC Riverside and its partners are exploring antiferromagnetic spintronics, a tech that could unlock lightning-fast, ultra-dense memory and smarter computing through quantum mechanics. The University of California, Riverside has been awarded nearly $4 million through the UC National Laboratory Fee
In recent years, many engineers have been trying to develop hardware components that could emulate the functions of various biological systems, including synapses, the human skin and nerves. These bio-inspired systems include what are referred to as artificial nerves, systems designed to emulate the role of nerves in the body of humans and other animals.
Artificial nerves could be useful for a wide range of applications, ranging from systems for repairing damaged nerves to brain-computer interfaces, highly precise sensors and other advanced electronics. So far, however, the engineering of nerve-inspired systems that operate at biologically compatible frequencies and realistically replicate the function of nerves has proved challenging.
Researchers at Xi’an Jiaotong University in China and Technical University of Munich recently developed a new high-frequency artificial nerve with a unique design that optimizes the transport of ions and electrons, while also rapidly responding to signals and retaining charge-related information. This nerve-inspired system, introduced in a paper published in Nature Electronics, is based on homogenously integrated organic electrochemical transistors.
Working at nanoscale dimensions, billionths of a meter in size, a team of scientists led by the Department of Energy’s Oak Ridge National Laboratory revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements, published in Nano Letters, could be used to advance technologies ranging from traditional computing to the emerging field of quantum computing.
Many materials undergo phase transitions characterized by temperature-dependent stepwise changes of important fundamental properties. Understanding materials’ behavior near a critical transition temperature is key to developing new technologies that take advantage of unique physical properties. In this study, the team used a nanoscale quantum sensor to measure spin fluctuations near a phase transition in a magnetic thin film. Thin films with magnetic properties at room temperature are essential for data storage, sensors and electronic devices because their magnetic properties can be precisely controlled and manipulated.
The team used a specialized instrument called a scanning nitrogen-vacancy center microscope at the Center for Nanophase Materials Sciences, a DOE Office of Science user facility at ORNL. A nitrogen-vacancy center is an atomic-scale defect in diamond where a nitrogen atom takes the place of a carbon atom, and a neighboring carbon atom is missing, creating a special configuration of quantum spin states. In a nitrogen-vacancy center microscope, the defect reacts to static and fluctuating magnetic fields, allowing scientists to detect signals on a single spin level to examine nanoscale structures.
This compares some of the ringworlds, centrifuges, space stations, and ships that use spin to make gravity. It also try’s to show how the variables of artificial gravity are used to make centripetal acceleration into spin gravity.
