Room-temperature qubit breakthrough as quantum computer race heats up

We are one step closer to a true quantum computer following a breakthrough which researchers say will allow qubits to be used at room-temperature.
One of the practical challenges of quantum computing has been the requirement to cool the quantum bits (qubits) to incredibly low temperatures, close to absolute zero and comparable to the temperature of space.
This super-cooling is necessary so that the quantum states of the qubit’s components remain ‘coherent’ and can perform comp
