Weak Value and Weak Measurements
The weak value of a variable O is a description of an effective interaction with that variable in the limit of weak coupling. For a pre-and post-selected system described at time t by the two-state vector Φ| |Ψ (see entry Two-State Vector Formalism), the weak value is [1]: O w ≡ Φ|O|Ψ Φ|Ψ. (1) Contrary to classical physics, variables in quantum mechanics might not have definite values at a give...
متن کاملEntanglement-assisted weak value amplification.
Large weak values have been used to amplify the sensitivity of a linear response signal for detecting changes in a small parameter, which has also enabled a simple method for precise parameter estimation. However, producing a large weak value requires a low postselection probability for an ancilla degree of freedom, which limits the utility of the technique. We propose an improvement to this me...
متن کاملThe Value of Weak Commitment
In biand multilateral interactions, parties frequently make weak commitments, i.e., commitments to future actions from which they may nonetheless deviate at some cost. For example, partners in a strategic alliance usually increase their mutual commitment step by step, where intermediate stages imply only a weak commitment. This paper proposes a new mechanism by which weak commitments lead to im...

متن کاملWhat is a quantum - mechanical ” weak value ” the value of ?
A so called “weak value” of an observable in quantum mechanics (QM) may be obtained in a weak measurement + post-selection procedure on the QM system under study. Applied to number operators, it has been invoked in revisiting some QM paradoxes (e.g., the so called Three-Box paradox and Hardy’s paradox). This requires the weak value to be interpreted as a bona fide property of the system conside...
