Low-noise semiconductor amplifier activates only when reading information from qubits enabling quantum computers with more qubits

"90% less power, reduces qubit decoherence, more powerful quantum computers... extremely sensitive microwave amplifiers ensures weak signals accurately detected/ read, but delicate, overcome by reducing heat since pulse-operated: activated only when needed for qubit amplification rather than being always switched on... smart amplifier uses algorithm improving operation... responds much faster to the incoming qubit pulse, in just 35 nanoseconds"
