Kobayashi Lab
Machine-translated · View original
A theory lab that explores quantum many-body systems and quantum error correction through the lens of “symmetry.”
AboutAbout the lab
Understanding the quantum world through symmetry
The Kobayashi Lab studies, through theory, quantum many-body systems (the quantum states formed by large numbers of particles) and the foundations of error correction for quantum computers.
In particular, the lab takes “symmetry” as its guiding principle and aims to systematically understand the fundamental properties of quantum many-body systems and error-correcting codes.
Its themes are broadly connected, ranging from abstract theory such as symmetry and field theory to lattice models, quantum error-correcting codes, and quantum computation.
Key terms
- Quantum error correction
- A mechanism that detects and corrects errors occurring during computation on a quantum computer by encoding information in a carefully designed way
- Topological phase
- A state of matter characterized by a mathematical property (topology) that does not change under smooth deformation
- Quantum anomaly
- A phenomenon in which a symmetry that holds in a classical theory is no longer preserved in the quantum theory

ResearchResearch themes
The lab works on condensed matter physics and fundamental problems in quantum error correction. Recently, its goal has been to systematically understand the fundamental properties of quantum many-body systems and error-correcting codes through the lens of “symmetry.”
*Illustrative imageSymmetries and Logical Gates of Error-Correcting Codes
In quantum error correction, it is important not only to have codes that are robust against errors but also to implement computation on the code (logical gates). The lab investigates the connection between the generalized symmetries hidden in codes and logical gates.
*Illustrative imageExtracting Invariants of Quantum Many-Body Systems
In materials in topological phases, special states appear at the edges. The lab studies methods to extract the “invariants” responsible for this as quantities that can actually be computed and measured.
*Illustrative imageHigher-Form Symmetries and Quantum Anomalies
The lab develops methods to directly define and compute, on lattice models, the “higher-form symmetry” that appears in topological order and elsewhere, together with the quantum anomalies associated with it.
*Illustrative imagePhysics of Symmetries Without Inverses
The lab studies quantum many-body systems with “non-invertible symmetries,” which have no inverse operation. It examines how responses resembling those of fractional quantum Hall systems, as well as phase classifications, emerge.
