D-Wave’s New Gate Keeps Its Qubits’ Errors Easy to Spot
Most qubits fail unnoticed. Something nudges the quantum state, the information corrupts, and the machine has no idea until error...
A Qubit That Lasts Longer, Because of What It’s Made Of
A superconducting qubit is a beautiful, fragile thing. It holds quantum information for a flicker, a fraction of a millisecond...
Qarakal Claims a Quantum Architecture Needing a Tenth the Qubits
Qarakal Quantum has unveiled a modular quantum-computing architecture it calls Pangaea, built around a “quantum bus” that shuttles information between...
OpenAI’s Astra Wrote New Quantum-Complexity Proofs. Do They Hold?
OpenAI says an internal model it calls Astra solved ten open problems in mathematics and theoretical computer science, and two...
The Navy’s Quantum Lab Focuses on Sensing and Algorithms
The U.S. Naval Research Laboratory (NRL) has spelled out what its year-old Quantum Science Institute works on, and the list...
A Quantum Advantage Result You Can Actually Check
Most quantum-advantage claims have two soft spots. You usually can’t verify the answer, since the whole point is that it’s...
A Warm Atom Cloud and a Cold Quantum Dot, Emitting Identical Photons
A quantum network is a mix-and-match problem. You want bright, fast photon sources for sending information, and you want atomic...
Where Classical Supercomputers Stopped Agreeing, a Quantum Chip Held On
Point one of the world’s fastest supercomputers at a hard enough physics problem and, eventually, it starts giving you answers...
The Lab That Bent Light Backwards Is Going Quantum
Natural materials bend light in predictable ways. Glass slows it and tilts it toward you, and water does much the...
Atomionics Aims Its Quantum Gravity Sensor at the Ocean
Atomionics wants to map the seabed by reading gravity. The Singapore company has opened a new quantum-sensing hub and is...
