Less-explored form of quantum code could be more powerful—and more stable—than its alternative in error correction
In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which sock goes on first). ...

Two independent studies push semiconductor qubits towards practical scales
Semiconductor spin qubits are one of the most promising building blocks for future quantum computers, but turning them into a working, large-scale quantum computer has so far proven difficult. For now, two big questions remain ...
Quantum spin effects may enhance one-way electrical transport in chiral magnets
Quantum fluctuations influence direction-dependent electrical transport in chiral magnets, researchers from Science Tokyo report. In chiral magnetic systems, electric current flows differently depending on its direction, ...

Light's hidden properties save quantum information from the chaos of bad weather
For years, researchers have tried to harness the "twist" of light to transmit data. This property describes how light spirals as it travels forward, and because it can be molded into a virtually infinite number of different ...

Physicists link the Riemann Hypothesis to phase transitions in quantum systems
A new study in Nature Communications has established a link between the Riemann Hypothesis and dynamical phase transitions in engineered quantum systems, demonstrating the effect on a quantum processor.
Physicists create Bose–Einstein condensate from ultracold polar molecules
Bose–Einstein condensates are states of matter that form when particles called bosons are cooled to temperatures that are only a fraction of a degree above absolute zero (i.e., 0 Kelvin [-460°F]). In these states, particles ...
Quantum in the palm of your hand: The evolution of superconducting qubits
Electrons zipping through transistors, powering the screens on our smartphones. Light zooming from distant stars to Earth, moving faster than anything else in the universe. Protons enabling MRI machines to analyze people's ...

2D quantum memory device reaches single-electron limit of information storage
Most electronic memory storage devices require the ability to trap large numbers of electrons for each bit of memory. In an ideal world, however, it would take only one electron. This would reduce space requirements and power ...
Rare-earth ions could enable telecom-ready control of interacting qubits
Quantum technologies are devices and systems that exploit the laws of quantum mechanics and could perform tasks that are difficult or impossible to tackle using their classical counterparts. These technologies process and ...
New research shows how 'hot electrons' can reshape metals in billionths of a second
Researchers at The University of Manchester have revealed how intense electronic excitation can trigger rapid structural changes in metals—without heating the atomic lattice—offering new insight into ultrafast materials behavior.

Quantum neural networks get their first hardware test
Neural networks have transformed how machines find patterns in data, from recognizing faces in photos to predicting the shapes of proteins. So far, all of this progress has been made on ordinary classical computers, but with ...
Near a black hole, gravity changes a quantum circuit's readings, not its rules
Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with ...
A quantum heat engine that simultaneously provides work and refrigeration
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...
Long-lived ytterbium states could sharpen quantum computing and atomic clocks
Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable ...
