چکیده

We study successive measurements of two observables using von Neumann’s measurement model. The two-pointer correlation for arbitrary coupling strength allows retrieving the initial system state. We recover Lüders rule, the Wigner formula and the Kirkwood-Dirac distribution in the appropriate limits of the coupling strength.

Comments on the Referee's Reports for Manuscript Foop1369, Submitted to Foundations of Physics, Entitled Quantum Weak Values Are Not Unique What Do They Actually Measure?

Most of the comments on the referee's reports will not be meaningful to someone who has not read the paper, so I may as well use the notation of the paper. For the reader's convenience, it is summarized below, but most readers will probably want to skip the summary, referring back to it only if needed. Symbols in the summary (such as A, s, f , etc.) will be used in the comments without further ...

A sequence of unsharp measurements enabling a real time visualization of a quantum oscillation

The normalized state |ψ(t)〉 = c1(t)|1〉 + c2(t)|2〉 of a single two-level system performs oscillations under the influence of a resonant driving field. It is assumed that only one realization of this process is available. We show that it is possible to approximately visualize in real time the evolution of the system as far as it is given by |c2(t)| 2. For this purpose we use a sequence of particu...

Endoscopic Tomography and Quantum-Non-Demolition

We propose to measure the quantum state of a single mode of the radiation field in a cavity— the signal field—by coupling it via a quantum-non-demolition Hamiltonian to a meter field in a highly squeezed state. We show that quantum state tomography on the meter field using balanced homodyne detection provides full information about the signal state. We discuss the influence of measurement of th...

2 00 1 Heisenberg exchange parameters of molecular magnets from the high - temperature susceptibility expansion

We provide exact analytical expressions for the magnetic susceptibility function in the high temperature expansion for finite Heisenberg spin systems with an arbitrary coupling matrix, arbitrary single-spin quantum number, and arbitrary number of spins. The results can be used to determine unknown exchange parameters from zero-field magnetic susceptibility measurements without diagonalizing the...

Quantum nondemolition measurement of a light field component by a feedback compensated beam splitter

In conventional quantum nondemolition measurements, the interaction between signal and probe preserves the measured variable. Alternatively, it is possible to restore the original value of the variable by feedback. In this paper, we describe a quantum nondemolition measurement of a quadrature component of the light field using a feedback compensated beam splitter. The noise induced by the vacuu...
