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 ...

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 ...

Quantum computing has the potential to handle complex problems at hyper-fast speeds. What makes this possible is the way it exploits qubits—typically subatomic particles such as electrons—that use ...

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 ...

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 ...

Researchers in China said they have found the first evidence that subatomic particles from cosmic rays may be affecting the efficiency of widely used error correction ...
