Specification and Runtime Checking of Derecho, A Protocol for Fast Replication for Cloud Services
Kumar Shivam, Vishnu Paladugu, Yanhong A. Liu
Reliable distributed systems require replication and consensus among distributed processes to tolerate process and communication failures. Understanding and assuring the correctnes…
Lorentzian geometry of qubit entanglement
Joseph Samuel, Kumar Shivam, Supurna Sinha
We study the relation between qubit entanglement and Lorentzian geometry. In an earlier paper, we had given a recipe for detecting two qubit entanglement. The entanglement criterio…
Detecting qubit entanglement : an alternative to the PPT test
Joseph Samuel, Kumar Shivam, Supurna Sinha
We propose a Partial Lorentz Transformation (PLT) test for detecting entanglement in a two qubit system. One can expand the density matrix of a two qubit system in terms of a tenso…
Entropy and Geometry of Quantum States
Kumar Shivam, Anirudh Reddy, Joseph Samuel +1
We compare the roles of the Bures-Helstrom (BH) and Bogoliubov-Kubo-Mori (BKM) metrics in the subject of quantum information geometry. We note that there are two limits involved in…
Coarse Quantum Measurement: An analysis of the Stern Gerlach experiment
Anirudh Reddy, Joseph Samuel, Kumar Shivam +1
We study the Quantum Measurement Process in a Stern-Gerlach setup with the spin of a silver atom as the quantum system and the position as the apparatus. The system and the apparat…
