Reliable Quantum Communication
2023 23rd International Conference on Transparent Optical Networks (ICTON), 2023 The quantum internet, which will be a hybrid of quantum and classical networks, is expected to provide information-theoretic security for data transmission. Classical networks have well-established protocols for reliable end-to-end transmission that use duplicating the classical bits implicitly.

Supersonic Quantum Communication [PDF]
Physical Review Letters, 2009 When locally exciting a quantum lattice model, the excitation will propagate through the lattice. The effect is responsible for a wealth of non-equilibrium phenomena, and has been exploited to transmit quantum information through spin chains. It is a commonly expressed belief that for local Hamiltonians, any such propagation happens at a finite "speed ...

Sensors, 2021 In this study, we focus on the 3D surface measurement and reconstruction of translucent objects. The proposed approach of surface-shape determination of translucent objects is based on the combination of the projected laser-beam-based sinusoidal ...

Enhancing the precision limits of interferometric satellite geodesy missions
npj Microgravity, 2022 Satellite geodesy uses the measurement of the motion of one or more satellites to infer precise information about the Earth’s gravitational field. In this work, we consider the achievable precision limits on such measurements by examining approximate ...

How Quantum is Quantum Counterfactual Communication? [PDF]
Foundations of Physics, 2021 AbstractQuantum Counterfactual Communication is the recently-proposed idea of using quantum physics to send messages between two parties, without any matter/energy transfer associated with the bits sent. While this has excited massive interest, both for potential ‘unhackable’ communication, and insight into the foundations of quantum mechanics, it has ...

Quantum steering with vector vortex photon states with the detection loophole closed
npj Quantum Information, 2022 Violating a nonlocality inequality enables the most powerful remote quantum information tasks and fundamental tests of quantum physics. Loophole-free photonic verification of nonlocality has been achieved with polarization-entangled photon pairs, but not

Quantum channel correction outperforming direct transmission
Nature Communications, 2022 Quantum channel correction could provide a remedy to unavoidable losses in long-distance quantum communication, but the break-even point has escaped demonstration so far.
