Quantum materials could transform technologies ranging from powerful computers and highly secure communications to advanced energy systems, but one major obstacle has long stood in the way.

Co-designed transversal STAR architecture
Co-designed transversal STAR architecture, published in PRX Quantum, delivers up to 250× faster execution and roughly 2× fewer physical qubits than conventional fault-tolerant approaches for structured quantum simulation — bringing the megaquop era within reach significantly sooner.
BOSTON, MA — June 1, 2026 — QuEra Computing today announced the publication in PRX Quantum of a new co-designed quantum computing architecture, developed in collaboration with Los Alamos National Laboratory, that significantly reduces the physical resources required for early fault-tolerant quantum simulation. The architecture — called transversal STAR (Space-Time Efficient Analog Rotation) — is co-designed with neutral-atom hardware and is targeted at structured quantum simulation problems in materials science, condensed matter and non-equilibrium dynamics.
AI & Quantum Computing Are Redefining Research & Development, Manufacturing & Technological Exploration
Chuck Brooks is the president of Brooks Consulting International and one of Executive Mosaic’s GovCon Experts.
The convergence of AI and quantum tech is creating a new frontier of innovation and risk.
This trend is evident from the White House’s FY27 research and development goals that put Artificial intelligence and quantum technologies at the center of the national agenda.
From one frontier to another: The quantum revolution
Manchester’s quantum researchers are building on the Ferranti Mark I legacy, using ultra-pure silicon and single atoms to move quantum computing closer to real-world impact.
In February 1951, a machine the size of a room arrived at the University of Manchester.
The Ferranti Mark I, the world’s first commercially available general-purpose computer, came with 4,000 vacuum tubes, 100,000 soldered joints and six miles (10 kilometers) of wires. The 27 kilowatts of power it needed to operate is the equivalent of running roughly 600 midrange laptops today, yet at the time, it must have felt miraculous.
Universal structure of exceptional points revealed in nonlinear light‑based systems
Exceptional points, or EPs for short, are among the phenomena of modern physics. These are special points or locations at which the properties of matter, space or time change. In a new theoretical study, researchers from the Institute for Photonic Quantum Systems (PhoQS) at Paderborn University, in collaboration with researchers from the University of Arizona, have shown that exceptional points in nonlinear systems follow a universal geometric order—something that was previously unclear. Their findings have been published in the journal Nature Communications.
Exceptional points are points in physical systems at which not only two eigenvalues but also the corresponding states merge. Such phenomena occur in so-called non-Hermitian systems, which are characterized, for example, by amplification, loss or interactions with their environment. They are the subject of intensive research in fields including optics, lasers, quantum systems and polariton condensates.
Until now, EPs have mainly been studied in linear systems. In such systems, they can often be described as isolated points in parameter space. However, many real physical systems are nonlinear: Their properties depend on the intensity, occupation or state of the system itself.
Quantum Newton’s cradle set to level up computing
Sending quantum information through a chain of qubits, like energy through a Newton’s cradle, could be the key to faster operations and take quantum computing to the next level.
The quantum Newton’s cradle design shows how a laser can be used to give a precisely designed kick of energy to a row of trapped ions, quickly preparing them for quantum calculations known as gates.
The superpower of the new algorithm is its ability to rapidly entangle any two ions in the row without affecting the ones in between: Like a Newton’s cradle, the energy travels through the ions, leaving them untouched.
Shaking atoms to bring black-hole quantum chaos into the lab
Physicists have discovered a surprisingly simple way to reproduce one of the most fascinating models in modern physics—linked to black holes, quantum chaos and exotic electronic materials—using ultracold atoms trapped in light.
Instead of trying to build a highly complex system from scratch, the researchers show that gently “shaking” a standard optical lattice can transform it into an accurate simulator of the Sachdev–Ye–Kitaev (SYK) model, a theoretical model known for its extreme and unusual quantum behavior.
The findings are published in the journal Physical Review Letters.
Northwestern University Researchers Demonstrate Quantum Entanglement Over Busy Telecom Fiber
Kumar and his team measured entanglement fidelity above 94%, confirming it survived the journey at a level impossible for a classical communications system to reproduce.
The study is a part of a broader shift toward integrating quantum technologies with existing telecommunications systems. Kumar and coauthor Jordan Thomas recently explored that evolution in a feature article for Optics & Photonics News.
Next, the team plans to perform quantum teleportation between remote nodes across a real-world telecommunications network. While Kumar has already performed teleportation in his lab, he wants to demonstrate it over a metropolitan fiber carrying commercial traffic.
