Explore quantum research, from error correction to new algorithms, with clear explanations of the evidence and the limits of each result.

A cold crystal preserved quantum correlations while information waited in a spin state. That is a useful component for a future network, with more work still to do.
A wireframe SQUID on a cantilever tackles the geometry of measuring very small magnetic signals.
Classical shadows help researchers estimate useful properties without reconstructing an entire quantum state.
A new benchmarking framework asks how much useful circuit a machine can handle, and how quickly it can handle it.
Michelle Y. Simmons, John Preskill and Krysta M. Svore offer three different ways to understand the work ahead.
A silicon-carbide experiment moved fragile quantum information into nuclear-spin memory at room temperature. It is a storage result, not a room-temperature supercomputer.
Stanford's magnetic brain-imaging system uses quantum-sensitive sensors close to the scalp. Better measurement is the aim; this is not a mind-reader.
A simulator using 13 active trapped-ion qubits explored how an electric-field string breaks in a simplified particle-physics model. The behavior began near the edges.
Researchers transferred an image through 100 separately addressable optical modes, testing how quantum state transfer can operate in parallel.
A mathematical comparison reveals advantages for quantum circuits on specific tasks, with the language-model architectures and resource limits carefully defined.
A microscopic resonator revealed the sudden loss of one phonon. Repeated measurements made the fleeting change visible.
A room-temperature experiment takes a faster route to entanglement. The important number is four, not millions.
An IBM preprint explores how to reduce the measurement burden behind cleaner answers. Its 63-fold figure needs a careful label.
A newly published photonics result puts several essential functions together. That is different from fitting an entire quantum computer on a chip.
The 13,000× benchmark estimate grabs attention. A result another quantum computer could check is the more useful idea.
A new blueprint turns helium’s tiny mass into a computing resource. The surprising part is what the atoms would do—not what they would cool.
Qubits can accumulate errors while they wait. A surface-code experiment shows why the pauses between operations deserve more attention.
Experiments with light make the order of quantum operations a controllable resource. The gain is specific—and it is not time travel.
Qudits use more than two quantum levels. They offer a different way to build and measure quantum information—not unlimited readable data.
Clavina combines programmable optics with specialized modules so one research platform can tackle different quantum tasks.
A new theoretical design tackles a basic problem: knowing when a useful pair of entangled photons is available.
The striking number concerns the work of designing a future quantum computer—not a quantum machine suddenly running every task faster.
A photonic experiment shows that the timing of a simple intervention can change when entanglement disappears.
A trapped ion shared a quantum connection across a 2.8-kilometer fiber loop carrying Ethernet and 5G traffic. The preprint tackles a practical networking problem.
