When Discarding Quantum Data Can Be Fair

A new paper explains why a filtered quantum result needs a filtered classical comparison. Its concrete example uses an experiment from 2015.

Quantum Error-Correction Software Can Misread Its Own Clues

A simulation study shows how reusing one clue can turn a correct repair into a wrong one, and how a small change to the software restores its advantage.

A Quantum Relay Used Memory to Bridge a City Fiber Link

Two trapped ions linked photons across existing city fiber. Remembering the first success helps connect it with the next, but this is one relay, not a network.

Five Silicon Qubits Share a Control Line. The Trick Is Taming Interference.

A shared microwave path makes the wiring simpler. Keeping neighboring qubits from disturbing each other is the harder part.

Claude Cut a Quantum Decoder's Costly Gates by About 12×

A smaller circuit can make a future quantum computer's job easier. The important change is in the instructions, not the chip.

Google Cut Errors in a Quantum Building Block by a Factor of 40

Cleaner, single-use quantum states could help power scientific calculations and future cryptographic attacks. The hard part is keeping them useful.

The US Put a Price on a Useful Quantum Computer

A $215 million competition defines usefulness as at least 100 logical qubits, hundreds of millions of fault-tolerant operations and a scientific demonstration. The numbers expose how far the field has moved beyond raw qubit counts.

A quantum sensor’s missing photons have a new way out

Aligned defects and nanopillars made selected silicon-carbide emitters brighter in a lab. Yield and system integration remain the harder scale tests.

A quantum battery needs more than speed

New theory separates how much energy a quantum battery transfers from how reliably it transfers it. The best model design is not necessarily the most collective.

Quantum computing needs a better test than qubit count

A bigger quantum computer can still fail at the calculation that matters. QUOPS and CUDA-Q Logical offer clearer ways to judge what a machine can do.
