Nonunitary gates using measurements only

Daniel Azses, Jonathan Ruhman, Eran Sela

Measurement-based quantum computation (MBQC) is a universal platform to realize unitary gates, only using measurements which act on a pre-prepared entangled resource state. By defo…

Scrambling in Ising spin systems with periodic transverse magnetic fields

Rohit Kumar Shukla

Scrambling of quantum information in both integrable and nonintegrable Floquet spin systems is studied. Our study employs tripartite mutual information (TMI), with negative TMI ser…

Nonrelativistic spatiotemporal quantum reference frames

Michael Suleymanov, Ismael L. Paiva, Eliahu Cohen

Quantum reference frames have attracted renewed interest recently, as their exploration is relevant and instructive in many areas of quantum theory. Among the different types, posi…

Single-pair measurement of the Bell parameter

Salvatore Virzì, Enrico Rebufello, Francesco Atzori +10

Bell inequalities are one of the cornerstones of quantum foundations, and fundamental tools for quantum technologies. Recently, the scientific community worldwide has put a lot of…

Multipartite entanglement and quantum error identification in -dimensional cluster states

Sowrabh Sudevan, Daniel Azses, Emanuele G. Dalla Torre +2

An entangled state is said to be -uniform if the reduced density matrix of any qubits is maximally mixed. This is intimately linked to pure quantum error correction codes (Q…

Time-symmetry and topology of the Aharonov-Bohm effect

Yakir Aharonov, Ismael L. Paiva, Zohar Schwartzman-Nowik +2

The Aharonov-Bohm (AB) effect has been highly influential in fundamental and applied physics. Its topological nature commonly implies that an electron encircling a magnetic flux so…

Quantum Engines and Refrigerators

Loris Maria Cangemi, Chitrak Bhadra, Amikam Levy

Engines are systems and devices that convert one form of energy into another, typically into a more useful form that can perform work. In the classical setup, physical, chemical, a…

Quantum circuits for measuring weak values, Kirkwood--Dirac quasiprobability distributions, and state spectra

Rafael Wagner, Zohar Schwartzman-Nowik, Ismael L. Paiva +5

Weak values and Kirkwood--Dirac (KD) quasiprobability distributions have been independently associated with both foundational issues in quantum theory and advantages in quantum met…

Multipartite Entanglement Detection via Correlation Minor Norm

Rain Lenny, Amit Te'eni, Bar Y. Peled +2

Entanglement is a uniquely quantum resource giving rise to many quantum technologies. It is therefore important to detect and characterize entangled states, but this is known to be…
