Cosmic rays may soon stymie quantum computing – Space Daily

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 information. Each qubit has the strange ability to be in a quantum superposition, carrying aspects of both states simultaneously, enabling a quantum version of parallel computation. Quantum computers, if they can be scaled to accommodate many qubits on one processor, could be dizzyingly faster, and able t…
