📡 Quantum Amplifier Noise: Phase-Insensitive vs Phase-Sensitive

Toggle a phase-insensitive amplifier against a phase-sensitive one and watch a live quadrature (phase-space) plot: the phase-insensitive noise blob grows equally in every direction and never beats the 3 dB standard quantum limit, while the phase-sensitive blob stretches in one quadrature (beating the limit there) and squeezes the perpendicular one (information lost).

Toggle a phase-insensitive amplifier against a phase-sensitive one and watch a live quadrature (phase-space) plot: the phase-insensitive noise blob grows equally in every direction and its noise figure never drops below the 3 dB standard quantum limit at any gain or angle, while the phase-sensitive blob stretches in one quadrature (beating that floor there) and squeezes the perpendicular one (information degraded). A live noise-figure-vs-quadrature-angle chart shows the phase-sensitive advantage is direction-dependent, not a free universal win.
