Arbitrary-Distance Quantum Error Correction with Gauss's Law for Lattice Gauge Theory
Neel S. Modi, Lento Nagano, Masazumi Honda +2
It has previously been shown by Rajput, Roggero, and Wiebe that Gauss's law constraints can be used to build efficient quantum error-correcting codes (QECCs) that are…
Gauss law codes and vacuum codes from lattice gauge theories
Javier P. Lacambra, Aidan Chatwin-Davies, Masazumi Honda +1
We develop a comprehensive framework for constructing quantum error correcting codes (QECCs) from Abelian lattice gauge theories (LGTs) using quantum reference frames (QRFs) as a u…
Evidence of a CP broken deconfined phase in 4D SU(2) Yang-Mills theory at from imaginary simulations
Mitsuaki Hirasawa, Masazumi Honda, Akira Matsumoto +2
The spontaneous breaking of CP symmetry in 4D SU() pure Yang-Mills theory at has recently attracted much attention in the context of the higher-form symmetry and the 't…
Numerical evidence for a CP broken deconfined phase at in 4D SU(2) Yang-Mills theory through simulations at imaginary
Mitsuaki Hirasawa, Masazumi Honda, Akira Matsumoto +2
We investigate the possibility of the spontaneous breaking of CP symmetry in 4D SU(2) Yang-Mills at , which has recently attracted much attention in the context of the highe…
Digital Quantum Simulation for Spectroscopy of Schwinger Model
Dongwook Ghim, Masazumi Honda
This note discusses a method for computing the energy spectra of quantum field theory utilizing digital quantum simulation. A quantum algorithm, called coherent imaging spectroscop…
