Gaussian quantum information [PDF]
Reviews of Modern Physics, 2012 The science of quantum information has arisen over the last two decades centered on the manipulation of individual quanta of information, known as quantum bits or qubits. Quantum computers, quantum cryptography and quantum teleportation are among the most celebrated ideas that have emerged from this new field.

Characterizing noise correlation and enhancing coherence via qubit motion
Fundamental Research, 2021 The identification of spacial noise correlation is of critical importance in developing error-corrected quantum devices, but it has barely been studied so far. In this work, we utilize an effective method called qubit motion, to efficiently determine the

Strategies for achieving high key rates in satellite-based QKD
npj Quantum Information, 2021 Quantum key distribution (QKD) is a pioneering quantum technology on the brink of widespread deployment. Nevertheless, the distribution of secret keys beyond a few 100 km at practical rates remains a major challenge.

Explaining the Unobserved: Why Quantum Mechanics Is Not only About Information [PDF]
, 2005 A remarkable theorem by Clifton, Bub and Halverson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance of the theorem is that quantum theory should be ...

Quantum-enhanced radiometry via approximate quantum error correction
Nature Communications, 2022 Exotic quantum states can be advantageous for sensing, but are very fragile, so that some form of quantum error correction is needed. Here, the authors show how approximate QEC helps overcoming decoherence due to noise when measuring the excitation ...

Strategies for Positive Partial Transpose (PPT) States in Quantum Metrologies with Noise
, 2021 Quantum metrology overcomes standard precision limits and has the potential to play a key role in quantum sensing. Quantum mechanics, through the Heisenberg uncertainty principle, imposes limits on the precision of measurements.

Quantum advantages for transportation tasks - projectiles, rockets and quantum backflow
npj Quantum Information, 2023 Consider a scenario where a quantum particle is initially prepared in some bounded region of space and left to propagate freely. After some time, we verify if the particle has reached some distant target region.
