Does anyone know what happened with these experiments?

Weak measurements are a type of quantum measurement technique that involves obtaining information about a quantum system without significantly perturbing it. This is achieved by using weakly interacting probes, such as photons, to interact with the system and obtain information about its state.
Weak measurements allow for the study of quantum systems without significantly altering their state, providing a more accurate picture of their behavior. They have also been used to reveal new insights into quantum mechanics, such as the measurement-disturbance relationship and the role of information in quantum systems.
In weak measurements, the system is first weakly coupled to a probe, causing a small change in the probe's state. The probe is then measured and the results are used to infer information about the system. By repeating this process multiple times, a more accurate measurement of the system's state can be obtained.
In 2007, a team of scientists led by Y. Aharonov and L. Vaidman proposed a new type of weak measurement called the "two-state vector formalism". This technique allows for the simultaneous measurement of two non-commuting observables, providing a more complete understanding of the quantum system.
Weak measurements are being used in a variety of fields, including quantum computing, quantum cryptography, and quantum sensing. They are also being used to study the behavior of complex systems, such as biological molecules, and to test fundamental principles of quantum mechanics.
