Quantum 10, 2020 (2026). https://doi.org/10.22331/q-2026-03-10-2020 The heralded exact one-way distillable secret key is equal to the largest expected rate at which perfect secret key bits can be probabilistically distilled from a bipartite state by means […]
Quantum 10, 2019 (2026). https://doi.org/10.22331/q-2026-03-10-2019 We introduce a systematic method for constructing polytope approximations to the quantum set in a variety of device-independent quantum random number generation (DI-QRNG) protocols. Our approach relies on two general-purpose […]
Quantum 10, 2018 (2026). https://doi.org/10.22331/q-2026-03-10-2018 We investigate the performance of an adiabatic evolution protocol when initialized from a Gibbs state at finite temperature. Specifically, we identify the diagonality of the final state in the energy […]
Quantum 10, 2017 (2026). https://doi.org/10.22331/q-2026-03-10-2017 Non-stabilizerness, alongside entanglement, is a crucial ingredient for fault-tolerant quantum computation and achieving a genuine quantum advantage. Despite recent progress, a complete understanding of the generation and thermalization of non-stabilizerness […]
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 […]
