Cosmic rays could pose a problem for future quantum computers

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 quantum properties to represent numerous combinations beyond the 0 or 1 of conventional bits. When pairs of qubits are “entangled,” they can change each other’s state in predictable ways, even at very…
