Original report snapshot

Original evidence: not verified

No attributable patent record was verified in the bounded search.

Records are counted separately from identified families. Author-reported entries are labelled and may still need publication verification. Inventorship, publication-time applicant and current ownership are different facts. No legal-status, patentability or freedom-to-operate conclusion is made.

Scores prioritize research fit from 1–10; they are not probabilities.

Review: Reviewed with limitations

Proposed capability matches, not confirmed relationships. Scores are analyst judgments with low forecast confidence; researcher interests, capacity and feasibility need confirmation.

Connection 1

Miri Blau

Research fit

Original proposal

Proposal hypothesis: Blau's quantum frequency transformations give Eliahu Cohen a concrete measurement system for testing distinguishability and uncertainty relations.[37][38][113][114]

Why this rank

Rank 1/10; fit 8/10: topic overlap 3/4, complementarity 3/3, first-test feasibility 2/3. Original initiative connection retained. No higher-scoring new candidate displaces this original. Independent review lowered feasibility by one point: Three modes, detector loss and a classical-mixture control give a useful scaffold, but the proposed measurement statistic is unnamed. Define the witness/estimator and its output criterion, or score feasibility 2/3 rather than 3/3. Equal scores retain originals first, then stable profile order. The underlying capabilities and proposed first test explain the component judgments. Specific scientific limitation: The score reflects a tractable optical-theory test, not an established quantum advantage.

Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.

Roy Zektzer

Tamar Goldzak Mizrahi

Why this rank

Rank 4/10; fit 8/10: topic overlap 3/4, complementarity 3/3, first-test feasibility 2/3. Added capability match outside the original initiative graph; prior collaboration or novelty was not established. Independent review lowered feasibility by one point: The temporal cavity and equal-energy comparison are plausible, but the test leaves the observable explicitly to be chosen. A 3/3 feasible-first-test score is premature until the measured quantity, quantum/classical input states and loss/noise model are fixed. The live Fridman page even lists joint quantum-temporal work, supporting topic fit without resolving this experimental specification. Equal scores retain originals first, then stable profile order. The underlying capabilities and proposed first test explain the component judgments. Specific scientific limitation: A temporal analogy alone does not establish quantum advantage.

Its proposed capability split: Proposal hypothesis: Fridman's temporal cavities provide a concrete optical system for Eliahu Cohen's questions about quantum time and measurement. Compare the cited first experiments; these are analyst priorities, not measured success rates. Equal scores retain originals first, then stable profile order. The underlying capabilities and proposed first test explain the component judgments. Specific scientific limitation: A quantum-measurement concept is not a demonstrated colloidal sensor; a concrete observable must precede hardware claims.

Added capability match outside the original initiative graph; prior collaboration or novelty was not established. Independent review lowered feasibility by one point: The toy lossy sensing model, estimated parameter and proposed quantum measurement are all unspecified. Equal-resource comparison is sound in principle, but the current prose does not justify maximum first-test feasibility. Equal scores retain originals first, then stable profile order. The underlying capabilities and proposed first test explain the component judgments. Specific scientific limitation: Statistical improvement must not be conflated with a general quantum advantage.

Independent review lowered feasibility by one point: The cited quantum-clock abstract concerns Page-Wootters clock frames and foundational uncertainty, not an engineered timing sensor. Define how a specific clock state produces the timing likelihood/noise model before assigning maximum feasibility; keep the existing low topic-overlap score. Equal scores retain originals first, then stable profile order. The underlying capabilities and proposed first test explain the component judgments.

Evidence & open questions

Inspect claim ratings and independent review

Eliahu Cohen works on quantum measurement, nonlocality and quantum time, including a 2023 quantum-clock study. [113][114]

High confidenceReview: reviewed

The roster uses the familiar Hebrew form Eli rather than the official Eliahu form.

Review record
  • root: supports. The university article body identifies Cohen and quantum time, measurement and nonlocality; the 2023 sole-author conference article confirms quantum-clock results. Its exact title differs from the initial profile draft and was flagged for correction.

Quantum-clock correction for ultra-low-field sensing is a future research hypothesis based on Cohen's theory and Mitchell's experimental quantum-sensing scope. [114][115]

Low confidenceReview: reviewed

No evidence yet shows that the formalism improves a physical sensor.
