Scientists at QuTech have achieved a major milestone in quantum computing by creating highly precise quantum gates on a diamond chip, hitting error rates as low as 0.001%. By using ultra-pure diamonds and advanced gate designs, the team overcame key challenges that have limited previous approache
In an attempt to speed up quantum measurements, a new Physical Review Letters study proposes a space-time trade-off scheme that could be highly beneficial for quantum computing applications.
Quantum computing has several challenges, including error rates, qubit stability, and scalability beyond a few qubits. However, one of the lesser-known challenges quantum computing faces is the fidelity and speed of quantum measurements.
The researchers of the study address this challenge by using additional or ancillary qubits to significantly reduce measurement time while maintaining or improving the quality of measurements.

More than 80 years ago, Erwin Schrödinger, a theoretical physicist steeped in the philosophy of Schopenhauer and the Upanishads, delivered a series of public lectures at Trinity College, Dublin, which eventually came to be published in 1944 under the title “What is Life?”
Now, in the 2025 International Year of Quantum Science and Technology, Philip Kurian, a theoretical physicist and founding director of the Quantum Biology Laboratory (QBL) at Howard University in Washington, D.C., has used the laws of quantum mechanics, which Schrödinger postulated, and the QBL’s discovery of cytoskeletal filaments exhibiting quantum optical features, to set a drastically revised upper bound on the computational capacity of carbon-based life in the entire history of Earth.
Published in Science Advances, Kurian’s latest work conjectures a relationship between this information-processing limit and that of all matter in the observable universe.
Physicists have made a major leap in our understanding of quantum entanglement by fully mapping out the statistics it can produce – essentially decoding the language of the quantum world.
This breakthrough reveals how the bizarre but powerful correlations in quantum systems can be used to test, secure, and certify the behavior of quantum devices, all without knowing their inner workings. The ability to self-test even partially entangled systems now opens doors to more robust quantum communication, encryption, and computing methods. It’s a game-changer for both fundamental physics and real-world quantum tech.
Cracking the code of quantum entanglement.
Our machines will be smart enough and eventually we will through intelligence enhancement.
For over a century, Einstein’s theories have been the bedrock of modern physics, shaping our understanding of the universe and reality itself. But what if everything we thought we knew was just the surface of a much deeper truth? In February 2025, at Google’s high-security Quantum A-I Campus in Santa Barbara, a team of scientists gathered around their latest creation — a quantum processor named Willow. What happened next would leave even Neil deGrasse Tyson, one of the world’s most renowned astrophysicists, in tears. This is the story of how a cutting-edge quantum chip opened a door that many thought would remain forever closed, challenging our most fundamental beliefs about the nature of reality. This is a story you do not want to miss.

This Quantum Computer Simulates the Hidden Forces That Shape Our Universe
The study of elementary particles and forces is of central importance to our understanding of the universe. Now a team of physicists from the University of Innsbruck and the Institute for Quantum Computing (IQC) at the University of Waterloo show how an unconventional type of quantum computer opens a new door to the world of elementary particles.

Majorana qubits could be error resistant. But after a contentious talk at the Global Physics Summit, scientists aren’t convinced Microsoft has them.
A standard commercial CMOS FET can exhibit synaptic-like long-term potentiation and depression or neuron-like leaky-integrate-and-fire and adaptive frequency-bursting behaviour when biased in a specific but unconventional way.
Superconductivity is a quantum physical state in which a metal is able to conduct electricity perfectly without any resistance. In its most familiar application, it enables powerful magnets in MRI machines to create the magnetic fields that allow doctors to see inside our bodies. Thus far, materials can only achieve superconductivity at extremely low temperatures, near absolute zero (a few tens of Kelvin or colder).
But physicists dream of superconductive materials that might one day operate at room temperature. Such materials could open entirely new possibilities in areas such as quantum computing, the energy sector, and medical technologies.
“Understanding the mechanisms leading to the formation of superconductivity and discovering exotic new superconducting phases is not only one of the most stimulating pursuits in the fundamental study of quantum materials but is also driven by this ultimate dream of achieving room-temperature superconductivity,” says Stevan Nadj-Perge, professor of applied physics and materials science at Caltech.
