Quantum 10, 2016 (2026). https://doi.org/10.22331/q-2026-03-09-2016 Quantum state discrimination plays a central role in quantum information and communication. For the discrimination of optical quantum states, the two most widely adopted measurement techniques are photon detection, which […]
Quantum 10, 2015 (2026). https://doi.org/10.22331/q-2026-03-09-2015 Finding a set of empirical criteria fulfilled by any theory satisfying the generalized notion of noncontextuality is a challenging task of both operational and foundational importance. This work presents a […]
Quantum 10, 2014 (2026). https://doi.org/10.22331/q-2026-03-09-2014 We use Pauli Path simulation to variationally obtain parametrized circuits for preparing ground states of various quantum many-body Hamiltonians. These include the quantum Ising model in one dimension, in two […]
Quantum 10, 2013 (2026). https://doi.org/10.22331/q-2026-03-09-2013 We provide a new characterisation of quantum supermaps in terms of an axiom that refers only to sequential and parallel composition. Consequently, we generalize quantum supermaps to arbitrary monoidal categories […]
Quantum 10, 2012 (2026). https://doi.org/10.22331/q-2026-03-05-2012 Universal features of chaotic quantum dynamics underlie our understanding of thermalization in closed quantum systems and the complexity of quantum computations. Reversible automaton circuits, comprised of classical logic gates, have […]
Quantum 10, 2011 (2026). https://doi.org/10.22331/q-2026-03-04-2011 Efficient verification of multipartite quantum states is crucial to many applications in quantum information processing. By virtue of Schmidt decomposition and mutually unbiased bases, here we propose a universal protocol […]
Quantum 10, 2010 (2026). https://doi.org/10.22331/q-2026-03-04-2010 States of open quantum systems often decay continuously under environmental interactions. Quantum Markov semigroups model such processes in dissipative environments. It is known that finite-dimensional quantum Markov semigroups with GNS […]
Quantum 10, 2009 (2026). https://doi.org/10.22331/q-2026-02-23-2009 Quantum computing is deemed to require error correction at scale to mitigate physical noise by reducing it to lower noise levels while operating on encoded logical qubits. Popular quantum error […]
Quantum 10, 2008 (2026). https://doi.org/10.22331/q-2026-02-23-2008 Unitary designs are essential tools in several quantum information protocols. Similarly to other design concepts, unitary designs are mainly used to facilitate averaging over a relevant space, in this case, […]
Quantum 10, 2007 (2026). https://doi.org/10.22331/q-2026-02-23-2007 We study the task of localizing multipartite entanglement in pure quantum states onto a subsystem by measuring the remaining systems. To this end, we fix a multipartite entanglement measure and […]
