PHY‑11: Intention Influence on Laser Emission Spectrum – Version 1.1 (Hardened)

Abstract

Protocol PHY‑11 v1.1 implements the unified metrological framework of Protocol 9.0 to test the claimed ability of human intention to alter the emission spectrum of a laser. Version 1.1 introduces independent wavelength meters for each laser, acoustic enclosures and increased operator distance (5 m), real‑time monitoring of back‑reflections, and a hysteresis test in the pilot phase to verify that the system is free from irreversible drifts. The protocol is designed for specialised optical laboratories with ultra‑stable lasers, high‑precision frequency metrology, and rigorous environmental control. Triple blinding, calibration perturbations, multiverse analysis, and a Minimum Detectable Effect (MDE) of 5σ above the Allan‑derived noise floor establish an uncompromising standard.

Optical Spectrum Analyzer with Quantum-Limited Noise Floor

Michael Bishof, Xiaogang Zhang, Michael J. Martin +1 more

Interactions between atoms and lasers provide the potential for unprecedented control of quantum states. Fulfilling this potential requires detailed knowledge of frequency noise in optical oscillators with state-of-the-art stability. We demonstrate a technique that precisely measures the noise spectrum of an ultrastable laser using optical lattice-trapped 87Sr atoms as a quantum projection noise-limited reference. We determine the laser noise spectrum from near dc to 100 Hz via the measured fluctuations in atomic excitation, guided by a simple and robust theory model. The noise spectrum yields a 26(4) mHz linewidth at a central frequency of 429 THz, corresponding to an optical quality factor of 1.6×10(16). This approach improves upon optical heterodyne beats between two similar laser systems by providing information unique to a single laser and complements the traditionally used Allan deviation which evaluates laser performance at relatively long time scales. We use this technique to verify the reduction of resonant noise in our ultrastable laser via feedback from an optical heterodyne beat. Finally, we show that knowledge of our laser's spectrum allows us to accurately predict the laser-limited stability for optical atomic clocks.

Quantum Metrology and Many-Body Physics: Pushing the Frontier of the Optical Lattice Clock

Michael J. Martin

Neutral atom optical standards require the highest levels of laser precision to operate near the limit set by quantum fluctuations. We develop state-of-the-art ultra-stable laser systems to achieve a factor of 10 enhancement in clock measurement precision and additionally demonstrate optical linewidths below 50 mHz. The most stable of these lasers reaches its thermal noise floor of 1 × 10-16 fractional frequency instability, allowing the attainment of near quantum-noise-limited clock operation with single-clock instabilities of 3×10-16 at 1 s. We utilize this high level of spectral resolution to operate a 87Sr optical lattice clock in a regime in which quantum collisions play a dominant role in the dynamics, enabling the study of quantum many-body physics. With a fractional level of precision of near 1 × 10-16 at 1 s, we clearly resolve the signatures of many-body interactions. We find that the complicated interplay between the p wave-dominated elastic and inelastic interaction processes between lattice-trapped atoms leads to severe lineshape distortion, shifts, and loss of Ramsey fringe contrast. We additionally explore the theoretical prediction that these many-body interactions will modify the quantum fluctuations of the system and we find that in certain parameter regimes the quantum noise distribution exhibits a quadrature dependence. We further present technological advancements that will permit ultra-stable lasers to operate with reduced thermal noise, leading to a potential gain of an additional factor of 10 in stability. This indicates that laser fractional frequency instabilities of 1 × 10-17 are within experimental reach, as is a fully-quantum-limited regime of optical clock operation.

PHY‑12: Intention Influence on Fluorescence of Quantum Dots – Version 1.1 (Hardened)

Vadim Streltsov

Protocol PHY‑12 v1.1 implements the unified metrological framework of Protocol 9.0 to test the claimed ability of human intention to alter the fluorescence properties of colloidal quantum dots (QDs). Version 1.1 introduces a common laser source with a beamsplitter for excitation, focus‑position monitoring, and a multivariate statistical approach (instead of univariate FDR) to handle multiple correlated observables. The protocol is designed for specialised optical laboratories with stringent control of QD stability, temperature, and environmental noise. Triple blinding, calibration perturbations, multiverse analysis, and a Minimum Detectable Effect (MDE) of 5σ above the Allan‑derived noise floor establish an uncompromising standard. The aggregation test is moved to a separate validation procedure.

High‐Precision Laser Spectrum Analyzer via Digital Decoherence (Laser Photonics Rev. 20(1)/2026)

Zhongwang Pang, Chunyi Li, Hongfei Dai +5 more

Digital Decoherence for Sub-Hertz Laser Analyzer In Research Article e01773, Bo Wang and co-workers propose the concept of digital decoherence. This allows the decoherence process to be realized through a digital delay. Based on this method, a laser spectrum analyzer is achieved for accurate frequency-noise power spectral density measurements of sub-Hertz linewidth lasers. This advance benefits quantum metrology, especially optical clocks.

PHY‑07: Remote Influence on a Pendulum

Vadim Streltsov

Protocol PHY‑07 implements the unified metrological framework of Protocol 9.0 to test the claimed ability of human intention to remotely alter the dynamics of a macroscopic pendulum. Version 2.0 incorporates a common invar baseplate for both pendulums to suppress differential vibrations, electrostatic shielding to eliminate charge‑induced artifacts, and a mandatory pilot phase with a fictitious operator to validate that the differential noise floor is indeed below the pre‑registered MDE. The protocol is designed for a specialised laboratory environment with active vibration isolation, high vacuum, and precision optical metrology. Triple blinding, calibration impulses, and multiverse analysis establish an uncompromising standard. The aim is detection of reproducible deviations from baseline or establishment of a quantitative upper bound on anomalous coupling.

PHY‑02: Ultra‑High‑Rigor Null‑Test Protocol for Macro‑Psychokinesis on a Mechanical Resonator

Vadim Streltsov

Protocol PHY‑02 implements the unified metrological framework of Protocol 9.0 for testing claimed macro‑psychokinesis (macro‑PK) — the alleged ability of human intention to produce measurable changes in the dynamics of a macroscopic mechanical resonator. The target system is a high‑Q resonator (tuning fork, quartz oscillator, or microcantilever) with amplitude, frequency, and phase as observables. The experimental architecture comprises physically isolated channels: an active resonator (target), a control resonator (dummy), and trap intervals. Version 2.0 introduces mandatory active temperature stabilisation, acoustic pressure monitoring, short‑time sliding‑window analysis, robust handling of non‑Gaussian noise, and extended kill criteria. Triple blinding, mandatory failure‑mode demonstration, multiverse analysis, and a Minimum Detectable Effect (MDE ≥ 5σ above the Allan‑deviation noise floor) establish an uncompromising metrological standard. The aim is detection of reproducible deviations from thermodynamic equilibrium or establishment of a quantitative upper bound, not confirmation of macro‑PK.
