GAN Decoder on a Quantum Toric Code for Noise‐Robust Quantum Teleportation

Advanced Quantum Technologies, Volume 8, Issue 11, November 2025.
This study proposes a novel quantum topological code decoder using generative adversarial networks (GANs). By training the GAN with eigenvalue datasets, an enhanced decoding threshold and robust quantum teleportation under depolarizing noise are achieved.

When strings surprise

Journal of High Energy Physics
We argue that on-shell excitations with large negative energies are created rapidly when the string coupling increases with time. This does not indicate an inconsistency in string theory since the negative energy on-shell excitation is always entangled ...

Stringy scaling of n-point Regge string scattering amplitudes

Journal of High Energy Physics, 2023
We discover a stringy scaling behavior for a class of n-point Regge string scattering amplitudes (RSSA). The number of independent kinematics variables is found to be reduced by dim M $$ \mathcal{M} $$ .

Symmetrization of Berezin Star Product and Path-Integral Quantization [PDF]

, 1999
We propose a new star pruduct which interpolates the Berezin and Moyal quantization. A multiple of this product is shown to reduce to a path-integral quantization in the continuous time limit.

Energy Symmetry Breaking of Dirac and Weyl Fermions in Magnetized Spinning Conical Geometries

Advanced Theory and Simulations, Volume 8, Issue 10, October 2025.
Exact solutions for relativistic fermions in magnetized, spinning conical geometries reveal defect‐induced symmetry breaking between fermion and antifermion energies. Energy levels depend on the magnetic field, background geometry, and fractionalized spin. When the defect's spin dominates, quantum effects diminish.

Moduli Space Dimensions of Multi-Pronged Strings [PDF]

, 1999
The numbers of bosonic and fermionic zero modes of multi-pronged strings are counted in ${\cal N}=4$ super-Yang-Mills theory and compared with those of the IIB string theory.

Spinor and Twistor Formulations of Tensionless Bosonic Strings in Four Dimensions [PDF]

, 2010
Spinor and twistor formulations of tensionless bosonic strings in 4-dimensional Minkowski space are constructed. We begin with a first-order action that is equivalent to the Nambu-Goto action in the tensionful case and that leads to a spinorial action in

Holomorphic field theories and higher algebra

Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware

Advanced Quantum Technologies, Volume 8, Issue 9, September 2025.
Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

Effective potential for revolving D-branes

Journal of High Energy Physics, 2019
We quantize an open string stretched between D0-branes revolving around each other. The worldsheet theory is analyzed in a rotating coordinate system in which the worldsheet fields obey simple boundary conditions, but instead the worldsheet Lagrangian ...
