Emergence of spacetime and gravity from quantum information
A central direction is the emergence of spacetime from quantum information, with a particular focus on how geometry changes when the underlying quantum state contains non-stabilizer structure, or magic. Stabilizer-based holographic codes capture important kinematic features of holography, such as entanglement wedge reconstruction and quantum error-correcting structure, but they are too rigid to describe genuinely dynamical geometry. In particular, they do not naturally capture gravitational backreaction or state-dependent changes in the bulk. This motivates the study of magic-enriched holographic codes, where non-stabilizer resources are introduced as controlled deformations of otherwise well-understood code constructions. In these models, the effective geometry is no longer determined solely by the stabilizer structure, but can depend on finer properties of the encoded quantum state.
A key question in this program is whether non-local magic plays a distinctive role in gravity. The aim is not simply to measure the amount of magic in a state, but to understand how its multipartite structure influences reconstruction, entropy, and the effective bulk description. In particular, this work explores whether non-local magic can act as a signature of gravitational backreaction, capturing how bulk geometry responds to the quantum state rather than remaining fixed in advance.
This perspective is developed using holographic quantum error-correcting codes, especially HaPPY-type models, where bulk and boundary entropies, recovery maps, and extremal-surface-like behavior can be studied explicitly. By introducing controlled non-stabilizer deformations into these codes, the goal is to determine which features of emergent spacetime follow from entanglement and error correction alone, and which require genuinely non-stabilizer quantum structure. More broadly, this provides a concrete route for moving beyond static toy models of holography toward a more dynamical picture of spacetime emerging from quantum information.
Experimental probes of quantum gravity
Another major direction is the development of experimental probes of quantum gravity using quantum information platforms. The goal is to translate abstract ideas from holography and quantum gravity into concrete protocols that can be implemented on quantum hardware. This includes designing noisy quantum circuits and tensor-network-based experiments that can test signatures of emergent geometry, entanglement structure, and recovery properties, making it possible to study aspects of quantum gravity in controlled laboratory settings rather than only through formal theory.
A central motivation is to lay the groundwork for future experimental tests of quantum gravity. Since any realistic implementation will necessarily involve noise, loss, and imperfect control, this also requires understanding the fault tolerance of the underlying protocols. In this context, holographic codes provide a useful setting for studying how information can remain protected under erasure and decoherence, and for learning which recovery mechanisms are robust enough to survive on real devices. Developing this understanding now is essential for moving from conceptual proposals to future experiments in which ideas from quantum gravity can be tested with controlled quantum systems.
Holography-inspired protocols for quantum technologies
Holography-inspired protocols for quantum technologies are studied by using insights from holographic quantum error correction, entanglement wedge reconstruction, and state-dependent/independent recovery to develop new ways of encoding, protecting, and processing quantum information. The goal is to identify principles from holography that are not only useful for understanding spacetime, but also valuable for quantum communication, decoding, and robust quantum architectures.
Quantum Error Correction
I also study practical quantum error correction as a separate research direction, focused on how quantum information can be encoded, protected, and recovered in the presence of noise. This includes the study of quantum codes, decoding and recovery protocols, and the principles of fault tolerance. The goal is to better understand robust quantum information storage and to develop tools for future quantum technologies. This direction is motivated by the fact that large-scale quantum computation and simulation will require reliable operation despite errors and decoherence. My work in this area contributes to the foundations of fault-tolerant quantum computing, robust quantum communication, and scalable quantum architectures. I am also interested in using ideas from holography, especially redundancy and reconstruction, to inform the study and design of quantum error-correcting codes.
