Hyperentanglement in Nanophotonic Systems With Discrete Rotational Symmetry

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
This work introduces a nanophotonic scheme leveraging discrete rotational symmetry to unlock two quantum capabilities: generation of hyperentangled photon pairs in spin and spatial degrees of freedom; and isomorphic mapping that preserves free‐space degrees of freedom, overcoming the information loss in non‐paraxial photonic systems.

Simulating Quantum State Transfer Between Distributed Devices Using Noisy Interconnects

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Noisy connections challenge future networked quantum computers. This work presents a practical method to address this by simulating an ideal state transfer over noisy interconnects. The approach reduces the high sampling cost of previous methods, an advantage that improves as interconnect quality gets better.

Asynchronous quantum computation through port-based teleportation

New Journal of Physics
In standard quantum teleportation, the receiver must wait for a classical message from the sender before subsequently processing the transmitted quantum information.

Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Photonic Unitary Circuits for Quantum Information Processing

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Unitary transformations are the cornerstone of quantum computing, enabling reversible manipulation of quantum states. This review evaluates photonic waveguide architectures as an evolving solution for quantum computing, exploiting the unique properties of photons. It investigates current theoretical frameworks, material platforms, and design strategies.

Relativistic Quantum Teleportation with Superconducting Circuits

, 2012
We study the effects of relativistic motion on quantum teleportation and propose a realizable experiment where our results can be tested. We compute bounds on the optimal fidelity of teleportation when one of the observers undergoes nonuniform motion for

Enhanced Spectral Range of Strain‐Induced Tuning of Quantum Dots in Circular Bragg Grating Cavities

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Experimental measurements and finite element simulations together reveal how stiff coating restores strain tunability in circular Bragg grating (CBG) quantum dot devices. Filling the CBG trenches with Al2O3 coating recovers up to 98% of the planar strain (εxx) while preserving cavity performance, enabling bright and tunable quantum light sources ...
