A study, “Enhanced Majorana stability in a three-site Kitaev chain,” published in Nature Nanotechnology demonstrates significantly enhanced stability of Majorana zero modes (MZMs) in engineered quantum systems.

This research, conducted by a team from the University of Oxford, Delft University of Technology, Eindhoven University of Technology, and Quantum Machines, represents a major step towards fault-tolerant quantum computing.

Majorana zero modes (MZMs) are exotic quasiparticles that are theoretically immune to environmental disturbances that cause decoherence in conventional qubits. This inherent makes them promising candidates for building robust quantum computers. However, achieving sufficiently stable MZMs has been a persistent challenge due to imperfections in traditional materials.

A new interdisciplinary study by researchers from the Ruth and Bruce Rappaport Faculty of Medicine and the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering at the Technion reveals a surprising insight: local release of dopamine—a molecule best known for its role in the brain’s reward system—is a key factor in acquiring new motor skills

A previously unknown trick lets you easily bypass using a Microsoft Account in Windows 11, just as Microsoft tries to make it harder to use local accounts.

Since the release of Windows 11, Microsoft has been increasingly closing loopholes and making it harder to use a local account in the operating system.

Instead, the company wants you to use a Microsoft Account, as many operating system features rely on cloud-based services.

Applied physicists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a photon router that could plug into quantum networks to create robust optical interfaces for noise-sensitive microwave quantum computers.

The breakthrough is a crucial step toward someday realizing modular, distributed quantum computing networks that leverage existing telecommunications infrastructure. Comprising millions of miles of optical fiber, today’s fiber-optic networks send information between computing clusters as pulses of light, or photons, all around the world in the blink of an eye.

Led by Marko Lončar, the Tiantsai Lin Professor of Electrical Engineering and Applied Physics at SEAS, the team has created a microwave-optical quantum transducer, a device designed for quantum processing systems that use superconducting microwave qubits as their smallest units of operation (analogous to the 1s and 0s of classical bits).

An international team led by Rutgers University-New Brunswick researchers has merged two lab-synthesized materials into a synthetic quantum structure once thought impossible to exist and produced an exotic structure expected to provide insights that could lead to new materials at the core of quantum computing.

The work, described in a cover story in the journal Nano Letters, explains how four years of continuous experimentation led to a novel method to design and build a unique, tiny sandwich composed of distinct atomic layers.

One slice of the microscopic structure is made of dysprosium titanate, an inorganic compound used in nuclear reactors to trap and contain elusive magnetic monopole particles, while the other is composed of pyrochlore iridate, a new magnetic semimetal mainly used in today’s experimental research due to its distinctive electronic, topological and magnetic properties.

Magnesium is a common chemical element, an alkaline earth metal, which is highly chemically reactive and is very light (even lighter than aluminum). Magnesium is abundant in plants and minerals and plays a role in human physiology and metabolism. In the cosmos, it is produced by large aging stars.

Among its physical properties, while it is a good conductor of electricity, magnesium is not known to be a superconductor. Superconductors are particularly promising materials with the potential to revolutionize , , and quantum computing, and are defined by their ability to conduct electricity without resistance below a certain critical temperature.

Recently, with my colleague Giovanni Ummarino from Turin Polytechnic, I have started challenging the textbook paradigm that states only certain elements in the periodic table can be superconductors. In particular, my colleague and I have shown that the phenomenon of can turn non-superconducting elements into superconductors. Our research is published in Condensed Matter.
