Surface ion traps are among the most promising technologies for scaling up quantum computing machines, but their complicated multi-electrode geometry can make some tasks, including compensation for stray electric fields, challenging both at the level of ...

Quantum steering with vector vortex photon states with the detection loophole closed
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

Implications of Local Friendliness Violation for Quantum Causality
We provide a new formulation of the Local Friendliness no-go theorem of Bong et al. [Nat. Phys. 16, 1199 (2020)] from fundamental causal principles, providing another perspective on how it puts strictly stronger bounds on quantum reality than Bell’s ...

Quantum channel correction outperforming direct transmission
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.

Quantifying Athermality and Quantum Induced Deviations from Classical Fluctuation Relations
In recent years, a quantum information theoretic framework has emerged for incorporating non-classical phenomena into fluctuation relations. Here, we elucidate this framework by exploring deviations from classical fluctuation relations resulting from the

Path integral formulation for quantum nonadiabatic dynamics and the mixed quantum-classical limit [PDF]
This work identifies geometric effects on dynamics due to nonadiabatic couplings in Born Oppenheimer systems and provides a systematic method for deriving corrections to mixed quantum-classical methods. Specifically, an exact path integral formulation of

Time-reversal symmetric work distributions for closed quantum dynamics in the histories framework [PDF]
A central topic in the emerging field of quantum thermodynamics is the definition of thermodynamic work in the quantum regime. One widely used solution is to define work for a closed system undergoing non-equilibrium dynamics according to the two-point ...

Nonlocality in Bell’s Theorem, in Bohm’s Theory, and in Many Interacting Worlds Theorising
“Locality” is a fraught word, even within the restricted context of Bell’s theorem. As one of us has argued elsewhere, that is partly because Bell himself used the word with different meanings at different stages in his career.

Scalable ion–photon quantum interface based on integrated diffractive mirrors
Quantum computing: high-resolution optics built directly into a micro-fabricated ion trap Building large-scale quantum computers or distributed networks of quantum computers requires small-scale nodes to be readily replicated and effectively connected ...
