Entanglement between superconducting qubits and a tardigrade

K. S. Lee, Y. P. Tan, L. H. Nguyen +8

Quantum and biological systems are seldom discussed together as they seemingly demand opposing conditions. Life is complex, "hot and wet" whereas quantum objects are small, cold an…

Moderate deviation expansion for fully quantum tasks

Navneeth Ramakrishnan, Marco Tomamichel, Mario Berta

The moderate deviation regime is concerned with the finite block length trade-off between communication cost and error for information processing tasks in the asymptotic regime, wh…

Incompatible measurements in quantum information science

Otfried Gühne, Erkka Haapasalo, Tristan Kraft +2

Some measurements in quantum mechanics disturb each other. This has puzzled physicists since the formulation of the theory, but only in recent decades has the incompatibility of me…

Optimal gain sensing of quantum-limited phase-insensitive amplifiers

Ranjith Nair, Guo Yao Tham, Mile Gu

Phase-insensitive optical amplifiers uniformly amplify each quadrature of an input field and are of both fundamental and technological importance. We find the quantum limit on the…
