Two-Layer Verification for Fault-Tolerant Magic-State Preparation in High-Rate Quantum Codes
Naoyuki Kanomata, Hayato Goto
Encoded magic states are essential for universal fault-tolerant quantum computation, but their resource-efficient preparation in high-rate quantum codes remains challenging. To add…
Fault-tolerant quantum computing with a high-rate symplectic double code
Naoyuki Kanomata, Hayato Goto
High-rate and large-distance quantum codes are expected to make fault-tolerant quantum computing more efficient, but most of them lack efficient fault-tolerant encoded-state prepar…
Relationship between a matrix model and harmonic oscillator systems
Harald Grosse, Naoyuki Kanomata, Akifumi Sako +1
A Hermitian matrix model with a Kontsevich-type kinetic term is studied. It was recently discovered that the partition function of this matrix model satisfies the Schrödinger…
Real symmetric -matrix model as Calogero-Moser model
Harald Grosse, Naoyuki Kanomata, Akifumi Sako +1
We study a real symmetric -matrix model whose kinetic term is given by , where is a positive diagonal matrix without degenerate eigenvalues. We show t…
Exact Solutions v.s. Perturbative Calculations of Finite - Hybrid-Matrix-Model
Naoyuki Kanomata, Akifumi Sako
There is a matrix model corresponding to a scalar field theory called Grosse-Wulkenhaar model, which is renormalizable by adding a harmonic oscillator potential to scalar t…
Exact solution of the finite matrix model
Naoyuki Kanomata, Akifumi Sako
We find the exact solutions of the finite matrix model (Grosse-Wulkenhaar model). In the finite matrix model, multipoint correlation functions are expressed…
