Q-CTRL has been selected for two awards under the DARPA Robust Quantum Sensors (RoQS) program, receiving contracts valued at A$38M (US$24.4M). The funding will support the development of next-generation quantum sensors for navigation on high-performance […]
According to Albert Einstein’s general theory of relativity, the behavior of a black hole depends on two numbers: how heavy it is, and how fast it is rotating. And that’s it. Black holes are said […]
Quantum 9, 1837 (2025). https://doi.org/10.22331/q-2025-08-27-1837 We derive a set of genuine multi-mode entanglement criteria for second moments of the quadrature operators. The criteria have a common form of the uncertainty relation between sums of variances […]
Quantum 9, 1836 (2025). https://doi.org/10.22331/q-2025-08-27-1836 Ground state energy estimation in physical, chemical, and materials sciences is one of the most promising applications of quantum computing. In this work, we introduce a new hybrid approach that […]
Quantum 9, 1835 (2025). https://doi.org/10.22331/q-2025-08-27-1835 We propose a two step strategy for estimating one-dimensional dynamical parameters of a quantum Markov chain, which involves quantum post-processing the output using a coherent quantum absorber and a “pattern […]
Quantum 9, 1834 (2025). https://doi.org/10.22331/q-2025-08-27-1834 Quantum signal processing (QSP) is a methodology for constructing polynomial transformations of a linear operator encoded in a unitary. Applied to an encoding of a state $rho$, QSP enables the […]
Postdoc position in bosonic quantum error correction, Paris (France) Submitted by frarzani on Wed, 27/08/2025 – 13:55. Application deadline: Sunday, November 30, 2025 A postdoctoral position is open to work with Francesco Arzani and the […]
Quantum technologies, devices that work by leveraging quantum mechanical effects, could outperform classical technologies in some fields and settings. The so-called spin (i.e., intrinsic angular momentum) carried by quantum particles is central to the functioning […]
Quantum 9, 1833 (2025). https://doi.org/10.22331/q-2025-08-27-1833 We significantly enhance the simulation accuracy of initial Trotter circuits for Hamiltonian simulation of quantum systems by integrating first-order Riemannian optimization with tensor network methods. Unlike previous approaches, our method […]
