Quantum Squeezing Yields Only 1.01 Gain in Planet-Mass Precision After Full Inference Chain
Preprint evaluates seven quantum receivers in optical interferometry and finds most advantages vanish after realistic loss and astrophysical inference. Only mode demultiplexing for binaries and limited squeezing in astrometry retain measurable gains. Evidence strength is limited by incomplete closure of the image-domain comparator.
Next steps require closing the event-level continuous-image comparator and measuring the broadband transfer matrix on-sky. Until those controls are demonstrated, reported gains remain provisional. Larger-aperture space interferometers now in concept studies could test these architectures within the next decade.
Turyshev: On-sky broadband transfer-matrix closure will confirm or refute >1.5 RMSE gains for binary masses within 24 months of first light.
