PhysicsWhy it might be impossible to build a practical quantum computer After “quantum supremacy”, the next step is scaling up and mastering the errors that dog qubits. But some researchers reckon the noise might always to be too high for useful quantum computers Features
PhysicsGoogle researchers made a time crystal inside a quantum computer A time crystal is a unique phase of matter that flips between two configurations with no energy input necessary – first proposed in 2012, this type of matter has now been created inside a quantum computer built by Google èƵ
