A Ramsey-type array of N unentangled qubits can detect wave-like dark matter with coupling sensitivity δα ∼ 1/(T√N), rivaling entangled-qubit schemes.
The noise spectrum an interferometer would see from quantum spacetime jitter is computed for vacuum, thermal, squeezed, and scalar-backreaction states; all are Planck-suppressed.
Proposes entangled vibrational qubits in linear Paul traps for detecting high-frequency gravitational waves via graviton-photon conversion or relative motion, with N-squared sensitivity enhancement.
A hemilithic OPA squeezed light source demonstrates up to 6.8 dB squeezing maintained at least 3 dB across 100 MHz bandwidth, with 8.6 dB inferred after dark noise correction, and 138 MHz linewidth claimed as broadest for long-term use.
Deformed alpha-attractor T-models with a Gaussian feature near the minimum yield more smaller shorter-lived oscillons during self-resonance preheating, suppressing energy in oscillons and altering the high-frequency gravitational wave tail while leaving low frequencies unchanged.

Self-resonance preheating in deformed attractor models: oscillon formation and evolution
