IonQ’s latest radar study asks a practical question: can a quantum model help separate real change from a noisy background?
A new benchmarking framework asks how much useful circuit a machine can handle, and how quickly it can handle it.
Riverlane’s planned Maryland headquarters puts error correction, university collaboration and the people building the stack in one story.
Michelle Y. Simmons, John Preskill and Krysta M. Svore offer three different ways to understand the work ahead.
EPB has launched an IonQ system alongside its quantum-networking facilities. The first research agenda includes the local electricity grid.
A new Maryland research center is an infrastructure story, but the more useful angle is how ambitious hardware claims will be tested.
A theoretical proposal connects trapped-ion quantum computing with electron microscopy. The attraction is learning more while doing less damage.
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.
A planned five-qubit machine in Campinas and cloud access to 54 qubits in Europe will give researchers hands-on hardware and a larger remote system.
DOE plans up to $215 million for protected qubits and long computations, with scientific demonstrations and verification central to the program.
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.
Superconducting detectors measured important X-ray features more precisely, helping scientists interpret overlapping signals from nuclear material.
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.
The hard part is not another futuristic chip. It is finding chemistry that separates valuable materials more effectively.
An IBM preprint explores how to reduce the measurement burden behind cleaner answers. Its 63-fold figure needs a careful label.
A new Alice & Bob and CEA collaboration is about making different machines work together, not declaring a winner.
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.
The collider is in a major upgrade shutdown. Quantum research is exploring possible tools for future analysis—not replacing the LHC or its computing grid.
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.
