Satellite-Relayed Global Quantum Communication without Quantum Memory Sumit Goswami and Sayandip Dhara Phys. Rev. Applied 20, 024048 (2023) – Published 18 August 2023 Physics logo Synopsis: Global Quantum Communication via a Satellite Train Long-distance quantum communication can usher in hack-proof communication, enable precision quantum sensing technologies, and ultimately yield a quantum Internet. Existing protocols for global-scale quantum communication demand high-performance quantum memories, which have limited communication distance. This study proposes a chain of satellites in low Earth orbit to directly transmit photonic qubits through space, using the satellites like optical lenses to counter diffraction loss. Simulations and analysis of different quantum communication protocols using this relay system show the feasibility of building a global quantum network of only satellites, without requiring quantum memories.

Applied 20, 024052 (2023) – Published 21 August 2023 Because any unitary operation is a rotation, in a sense measuring rotation is the most universal sort of measurement. In practice, precise rotation measurements are essential, from magnetometry to inertial navigation to fundamental tests of physics. The ultimate limits for simultaneously measuring all of the components of a rotation are dictated by quantum theory, and here are tested using light’s orbital angular momentum and multiplane light conversion. Rotated states are projected onto a set of coherent states to deduce the rotation parameters, using a method inspired by GPS. The results are near the ultimate limits of quantum precision.

This quantum-time-transfer technique can quickly achieve picosecond-level clock synchronization despite relatively low-performance quantum-photon sources and detection equipment.

Although quantum protocols have enabled remarkable breakthroughs here, their limitations have spurred classical alternatives undergirded by the physics of superposition of coherent waves, but these are extremely difficult to implement under realistic noisy environments. The authors propose and demonstrate with random optical waves a factoring protocol that is free from this shortcoming. Their theory also exposes a fundamental link between statistical optics and number theory. This protocol may trigger advances in factoring with acoustic and matter waves as well.

Applied 20, 024052 (2023) – Published 21 August 2023 Because any unitary operation is a rotation, in a sense measuring rotation is the most universal sort of measurement. In practice, precise rotation measurements are essential, from magnetometry to inertial navigation to fundamental tests of physics. The ultimate limits for simultaneously measuring all of the components of a rotation are dictated by quantum theory, and here are tested using light’s orbital angular momentum and multiplane light conversion. Rotated states are projected onto a set of coherent states to deduce the rotation parameters, using a method inspired by GPS. The results are near the ultimate limits of quantum precision.

Nicholas Lanning Phys. Rev. Applied 20, 024064 (2023) – Published 25 August 2023 Precise clock synchronization is important for quantum networking, enhanced position, navigation, timing, and other applications that require clock synchronization better than GPS, but remains an ongoing challenge. The authors propose a solution using hardware native to quantum networking. This quantum-time-transfer technique can quickly achieve picosecond-level clock synchronization despite relatively low-performance quantum-photon sources and detection equipment. Furthermore, it is robust against the high loss and high noise channel conditions representative of daytime space-Earth links, and could provide high-precision secure timing in GPS-denied environments.

Rev. Applied 20, 024072 (2023) – Published 29 August 2023 This work demonstrates experimentally that the advantage gained in sensing using quantum photonic resources can be sustained, and even amplified, through complex classical post-processing aimed at extracting relevant features. Despite the very different architectures of the classical algorithms tested here, the quantum advantage in classification performance appears to be robust and qualitatively very consistent. Thus the results argue for widespread use of quantum sensing technologies, in any field that deals with pattern recognition in large datasets.

Rev. Applied 20, 024073 (2023) – Published 29 August 2023 Know your enemy: In practical inline systems for continuous-variable quantum key distribution, the local oscillator (LO) is particularly vulnerable to being controlled by hackers. The authors propose a modified LO intensity attack with random fluctuations, which has the advantage of evading the commonly used monitoring technologies. Moreover, similar quantum hacking could also target the pilot intensity in a LO system, which indicates the strong adaptability and practicability of the proposed attack. This work could be of great significance to the practical security of continuous-variable quantum key distribution.
