Quantum 6, 733 (2022). https://doi.org/10.22331/q-2022-06-09-733 Motivated by the many-body localization (MBL) phase in generic interacting disordered quantum systems, we develop a model simulating the same eigenstate structure like in MBL, but in the random-matrix setting. […]
Quantum 6, 732 (2022). https://doi.org/10.22331/q-2022-06-07-732 Starting from arbitrary sets of quantum states and measurements, referred to as the prepare-and-measure scenario, an operationally noncontextual ontological model of the quantum statistics associated with the prepare-and-measure scenario is […]
Quantum 6, 731 (2022). https://doi.org/10.22331/q-2022-06-07-731 The notion of topology in physical systems is associated with the existence of a nonlocal ordering that is insensitive to a large class of perturbations. This brings robustness to the […]
Quantum 6, 730 (2022). https://doi.org/10.22331/q-2022-06-07-730 We propose an algorithm based on variational quantum imaginary time evolution for solving the Feynman-Kac partial differential equation resulting from a multidimensional system of stochastic differential equations. We utilize the […]
Quantum 6, 729 (2022). https://doi.org/10.22331/q-2022-06-07-729 Qubit routing is a key problem for quantum circuit compilation. It consists in rewriting a quantum circuit by adding the least possible number of instructions to make the circuit compliant […]
Are quantum computers overhyped? A new study in Nature says no. A cleverly-designed quantum device developed by Xanadu, a company based in Toronto, Canada, obliterated conventional computers on a benchmark task that would otherwise take […]
Quantum 6, 728 (2022). https://doi.org/10.22331/q-2022-06-02-728 We introduce a new method for analysing the Bose-Hubbard model for an array of bosons with nearest neighbor interactions. It is based on a number-theoretic implementation of the creation and […]
Quantum 6, 727 (2022). https://doi.org/10.22331/q-2022-05-30-727 In this work we present the Scaled QUantum IDentifier (SQUID), an open-source framework for exploring hybrid Quantum-Classical algorithms for classification problems. The classical infrastructure is based on PyTorch and we […]
Quantum 6, 726 (2022). https://doi.org/10.22331/q-2022-05-30-726 Using quantum algorithms to simulate complex physical processes and correlations in quantum matter has been a major direction of quantum computing research, towards the promise of a quantum advantage over […]
Quantum 6, 725 (2022). https://doi.org/10.22331/q-2022-05-30-725 Oblivious transfer is a cryptographic primitive where Alice has two bits and Bob wishes to learn some function of them. Ideally, Alice should not learn Bob’s desired function choice and […]
