Quantum entanglement is key to solving 250-year-old maths problem
Analysis of a mathematical puzzle that Leonhard Euler deemed unsolvable in the 1700s reveals that the crucial ingredient for cracking it after all is quantum entanglement.
A strange crystal made of electrons just revealed its hidden motion
Physicists have found a new way to peer inside one of matter’s most elusive quantum states: the Wigner crystal, where electrons stop behaving like independent particles and organize into a crystal-like pattern.
More realistic benchmarks for quantum algorithms
Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place.
The proton is more quantum than we thought
Our understanding of the internal structure of protons is largely based on classical physics, but data compiled from accelerator experiments has uncovered quantum behaviour that has never been seen before.
Scientific advancement has never been more prolific—so why has trust in science plummeted?
From genome editing to quantum computing, scientific progress is accelerating at an unprecedented pace, yet public faith in science is collapsing. Our species has mapped the human genome, created powerful computers that sit in the palms of our hands and extended human life spans
Quantum heat circuits learn electronics' oldest trick: Sharing a power supply
Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or package after the fact. They treat heat as a single average
Discovery of 'slow' electrons in 2D material could lead to new memory device
Over the last decade, researchers have developed two-dimensional materials with fascinating quantum effects that could be harnessed for next-generation technologies.
Quantum voting trickery could make elections more secure
In an election, how can you make sure that everyone's votes are counted but also kept entirely secret? Quantum mechanics may have the answer

Controlled cracking technique prints quantum dots into tiny pixels for sharper displays
Recent technological advances have enabled the development of increasingly sophisticated, sharper displays for electronic devices. Many modern displays use light-emitting diodes, or LEDs, tiny semiconductor-based components that emit light when an electrical current passes throug
Two-qubit entangling gate flags its own errors as detectable photon losses
Quantum errors are a normal part of quantum computing because fragile physical qubits (the tiny components storing data) can easily break down because of environmental noise, like heat, stray signals or microscopic vibrations. Typical fixes involve vast amounts of extra hardware
