  We combine phase-only transformations with fully-transmitting linear-optical scatterers to define the principle of linear-optical phase amplification. A particular phase amplifier is experimentally realized, allowing the phase enhancement parameter $dgamma/dphi$ to be continuously tuned. Placing this enhanced phase shifter in one arm of a Mach-Zehnder interferometer led to an intensity-phase slope more than twenty times steeper than what can be obtained with its unamplified counterpart.

We analyse the generation of random states in PQCs under restrictions on the qubits connectivities. We place a connection between how steep is the increase on the uniformity of the distribution of the generated states and the generation of entanglement.

  Low-noise microwave amplification is crucial for detecting weak signals in quantum technologies and radio astronomy. Current amplifiers do not satisfy all these requirements, severely limiting the scalability of superconducting quantum devices. Here, we demonstrate the feasibility of building a near-ideal quantum amplifier using a homogeneous Josephson junction array and the non-trivial topology of its dynamics.
