-squeezing and many-body entanglement geometry in finite-dimensional systems
Giuseppe Vitagliano, Otfried Gühne, Géza Tóth
Generalizing the well-known spin-squeezing inequalities, we study the relation between squeezing of collective -particle operators and many-body entanglement geometry in…
Collective randomized measurements in quantum information processing
Satoya Imai, Géza Tóth, Otfried Gühne
The concept of randomized measurements on individual particles has proven to be useful for analyzing quantum systems and is central for methods like shadow tomography of quantum st…
Quantum non-demolition measurement enables macroscopic Leggett-Garg tests
Costantino Budroni, Giuseppe Vitagliano, Giorgio Colangelo +4
We show how a test of macroscopic realism based on Leggett-Garg inequalities (LGIs) can be performed in a macroscopic system. Using a continuous-variable approach, we consider quan…
