Logical Entropy for Quantum States
Boaz Tamir, Eliahu Cohen
The novel concept of quantum logical entropy is presented and analyzed. We prove several basic properties of this entropy with regard to density matrices. We hereby motivate a diff…
Quantum Oblivion: A Master Key for Many Quantum Riddles
Avshalom C. Elitzur, Eliahu Cohen
A simple quantum interaction is analyzed, where the paths of two superposed particles asymmetrically cross, while a detector set to detect an interaction between them remains silen…
A comment on "How the result of a single coin toss can turn out to be 100 heads"
Eliahu Cohen
In [1] the authors claim that "weak values are not inherently quantum but rather a purely statistical feature". I argue that their model reproduces only few elements of weak measur…
Nonlocal Measurements via Quantum Erasure
Aharon Brodutch, Eliahu Cohen
Non-local observables play an important role in quantum theory, from Bell inequalities and various post-selection paradoxes to quantum error correction codes. Instantaneous measure…
How to Measure Magnetic Flux with a Single Position Measurement?
Eliahu Cohen, Lev Vaidman, Yakir Aharonov
Current methods for measuring magnetic flux are based on performing many measurements over a large ensemble of electrons. We propose a novel method based on wavefunction "revival"…
Measurement and Collapse within the Two-State-Vector Formalism
Yakir Aharonov, Eliahu Cohen, Eyal Gruss +1
The notion of collapse is discussed and refined within the Two-State-Vector Formalism (TSVF). We show how a definite result of a measurement can be fully determined when considerin…
