Scientists Make First Mechanical Qubit

Quantum computers that can theoretically find answers to problems no regular computer could ever solve rely on components known as qubits. Now scientists have created the first mechanical qubit—basically, a microscopic version of a drum skin that can behave a bit like Schrödinger’s cat, both vibrating and not vibrating at…
