While superconducting qubits are great at fast calculations, they struggle to store information for long periods. A team at Caltech has now developed a clever solution: converting quantum information into sound waves. By using a […]
The same technology behind MRI images of injury or disease also powers nuclear magnetic resonance (NMR) spectroscopy, which is used to analyze biological molecules for research on diseases and therapeutics. While NMR spectroscopy produces valuable […]

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 […]
