Cosmic intruders: Energetic particles from space and natural background radiation can trigger hard-to-correct errors when they collide with chips containing superconducting qubits. (Courtesy: Chris ...

Quantum computers are advancing at an exciting pace, but unfortunately this progress may soon stall. Cosmic rays streaming down to Earth could interfere with the integrity of the information in these ...

A new academic paper reveals a worrisome tendency for cosmic rays to disrupt quantum computer processors in a way that may be nearly impossible for current error ...

Nearly a fifth of all difficult-to-correct errors in quantum computers are caused by powerful particles from space hitting the machines. While these cosmic ray-induced errors have long been predicted ...

Researchers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have shown that they have a functional capability that can drastically speed up the testing of qubits. What used ...

The practicality of quantum computing hangs on the integrity of the quantum bit, or qubit. Qubits, the logic elements of quantum computers, are coherent two-level systems that represent quantum ...

Recently, when researchers were testing error correction on Google’s quantum processor, they noted an odd phenomenon where the whole error-correction scheme would ...
