• Unifying and benchmarking state-of-the-art quantum error mitigation techniques
  June 6, 2023 by Quantum journal
  Quantum 7, 1034 (2023). https://doi.org/10.22331/q-2023-06-06-1034 Error mitigation is an essential component of achieving a practical quantum advantage in the near term, and a number of different approaches have been proposed. In this work, we recognize that many state-of-the-art error mitigation methods share a common feature: they are data-driven, employing classical data obtained from runs of […]

• Researchers demonstrate secure information transfer using spatial correlations in quantum entangled beams of light
  June 6, 2023 by ScienceDaily | Quantum Computing News
  Researchers have demonstrated the principle of using spatial correlations in quantum entangled beams of light to encode information and enable its secure transmission.
• Measurement disturbance and conservation laws in quantum mechanics
  June 5, 2023 by Quantum journal
  Quantum 7, 1033 (2023). https://doi.org/10.22331/q-2023-06-05-1033 Measurement error and disturbance, in the presence of conservation laws, are analysed in general operational terms. We provide novel quantitative bounds demonstrating necessary conditions under which accurate or non-disturbing measurements can be achieved, highlighting an interesting interplay between incompatibility, unsharpness, and coherence. From here we obtain a substantial generalisation of […]
• The $2T$-qutrit, a two-mode bosonic qutrit
  June 5, 2023 by Quantum journal
  Quantum 7, 1032 (2023). https://doi.org/10.22331/q-2023-06-05-1032 Quantum computers often manipulate physical qubits encoded on two-level quantum systems. Bosonic qubit codes depart from this idea by encoding information in a well-chosen subspace of an infinite-dimensional Fock space. This larger physical space provides a natural protection against experimental imperfections and allows bosonic codes to circumvent no-go results that […]
