Quantum 7, 1015 (2023). https://doi.org/10.22331/q-2023-05-23-1015 Relational Quantum Mechanics (RQM) claims to be an interpretation of quantum theory [20]. However, there are significant departures from quantum theory: (i) in RQM measurement outcomes arise from interactions which […]
Quantum 7, 1014 (2023). https://doi.org/10.22331/q-2023-05-23-1014 Physical unclonable functions(PUFs) provide a unique fingerprint to a physical entity by exploiting the inherent physical randomness. Gao et al. discussed the vulnerability of most current-day PUFs to sophisticated machine […]
Quantum 7, 1013 (2023). https://doi.org/10.22331/q-2023-05-23-1013 We propose a category-theoretic definition of retrodiction and use it to exhibit a time-reversal symmetry for all quantum channels. We do this by introducing retrodiction families and functors, which capture […]
Quantum 7, 1012 (2023). https://doi.org/10.22331/q-2023-05-22-1012 Metric adjusted skew information, induced from quantum Fisher information, is a well-known family of resource measures in the resource theory of asymmetry. However, its asymptotic rates are not valid asymmetry […]
Quantum 7, 1011 (2023). https://doi.org/10.22331/q-2023-05-22-1011 We introduce a classical algorithm to approximate the free energy of local, translation-invariant, one-dimensional quantum systems in the thermodynamic limit of infinite chain size. While the ground state problem (i.e., […]
Quantum 7, 1010 (2023). https://doi.org/10.22331/q-2023-05-22-1010 Communication complexity is the amount of communication needed to compute a function when the function inputs are distributed over multiple parties. In its simplest form, one-way communication complexity, Alice and […]
Quantum 7, 1009 (2023). https://doi.org/10.22331/q-2023-05-22-1009 We introduce a new framework for contextuality based on simplicial sets, combinatorial models of topological spaces that play a prominent role in modern homotopy theory. Our approach extends measurement scenarios […]
Quantum 7, 1008 (2023). https://doi.org/10.22331/q-2023-05-15-1008 We describe a complete method for a precise study of gravitational interaction between two nearby quantum masses. Since the displacements of these masses are much smaller than the initial separation […]
Quantum 7, 1007 (2023). https://doi.org/10.22331/q-2023-05-15-1007 We propose, formulate and examine novel quantum systems and behavioral phases in which momentary choices of the system’s memories interact in order to source the internal interactions and unitary time […]
Quantum 7, 1006 (2023). https://doi.org/10.22331/q-2023-05-15-1006 Quantum computing testbeds exhibit high-fidelity quantum control over small collections of qubits, enabling performance of precise, repeatable operations followed by measurements. Currently, these noisy intermediate-scale devices can support a sufficient […]
