Quantum states can only be created and observed under tightly controlled conditions. A research team from Innsbruck, Austria, has successfully created so-called hot Schrödinger cat states in a ...

There are high hopes for quantum computers: they are supposed to perform specific calculations much faster than current supercomputers and, therefore, solve scientific and practical problems that are ...

A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ordinary computers faithfully mimic a fault-tolerant quantum circuit built on ...
