Challenges for extensions of the process matrix formalism to quantum field theory
Nikola Paunkovic, Marko Vojinovic
We discuss the issues with tentative generalisations of the process matrix formalism from finite-dimensional mechanical systems all the way to quantum field theory. We present a de…
Operational interpretation of the vacuum and process matrices for identical particles
Ricardo Faleiro, Nikola Paunkovic, Marko Vojinovic
This work overviews the single-particle two-way communication protocol recently introduced by del Santo and Dakić (dSD), and analyses it using the process matrix formalism. We give…
Generation and Distribution of Quantum Oblivious Keys for Secure Multiparty Computation
Mariano Lemus, Mariana F. Ramos, Preeti Yadav +6
The oblivious transfer primitive is sufficient to implement secure multiparty computation. However, secure multiparty computation based only on classical cryptography is severely l…
Experimental Semi-quantum Key Distribution With Classical Users
Francesco Massa, Preeti Yadav, Amir Moqanaki +5
Quantum key distribution, which allows two distant parties to share an unconditionally secure cryptographic key, promises to play an important role in the future of communication.…
Causal orders, quantum circuits and spacetime: distinguishing between definite and superposed causal orders
Nikola Paunkovic, Marko Vojinovic
We study the notion of causal orders for the cases of (classical and quantum) circuits and spacetime events. We show that every circuit can be immersed into a classical spacetime,…
Vanishing k-space fidelity and phase diagram's bulk-edge-bulk correspondence
P. D. Sacramento, B. Mera, N. Paunkovic
The fidelity between two infinitesimally close states or the fidelity susceptibility of a system are known to detect quantum phase transitions. Here we show that the k-space fideli…
