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 ...

It takes a spy to hunt a spy.

Infinitesimally low levels of radiation, such as from incoming cosmic rays, may soon stymie progress in quantum computing. The practicality of quantum computing hangs on the integrity of the quantum ...

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 ...

“Do you believe in the multiverse?” our petite and cheerful guide Angelina asked me when I told her what I do for a living, while navigating the rambunctious street’s of Hanoi’s Old Quarter. It was ...

Qubits, the logic elements of quantum computers, are coherent two-level systems that represent quantum information. Each qubit has the strange ability to be in a quantum superposition, carrying ...

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 ...

"Cosmic Quantum Ray" is a zany comedy-action-adventure series that brings the strange corners of the universe to the world of Earth teenager Robbie Shipton. Robbie represents Earth as a member of Team ...

High-energy astrophysics investigates the most energetic processes in the Universe, from the acceleration of charged particles in supernova remnants to the production of ultra-high-energy neutrinos ...

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

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 ...

Research by a Lawrence Livermore National Laboratory (LLNL) physicist and a group of collaborators is shedding light on one of the major challenges to realizing the ...
