As the name suggests, the gadget amplifies weak signals selected up from the qubits to conduct the readout, which causes undesirable noise and can lead to decoherence of the qubits if not secured by extra big elements. The bulky size of the amplification chain becomes technically challenging to work around as qubit counts increase in size-limited refrigerators.Bolometer-Based Qubit MeasurementCue the Aalto University research group Quantum Computing and Devices (QCD).

As the name suggests, the gadget magnifies weak signals picked up from the qubits to conduct the readout, which causes unwanted sound and can lead to decoherence of the qubits if not secured by additional big components.
