Quantum Economics AI Lab

Research at the intersection of economics, artificial intelligence, and quantum-inspired mathematical formalism.

Core Insight

Price is not a fixed value.

Before a transaction occurs, market prices exist as a probability distribution.

A trade acts as a measurement collapsing uncertainty into an observed price.

Research Programs
01

Quantum Finance

Theoretical

Applying quantum probability to asset pricing and portfolio theory. We develop non-Kolmogorovian probability models and path-integral methods to capture interference effects in market dynamics and option pricing under non-Gaussian distributions.

Selected Research

A Probabilistic Framework for Asset Valuation under Quantum Formalism

Liu, Y. (2025)Quantum Finance ProgramWork in Progress

We develop a quantum-inspired framework for asset valuation, where prices are modeled as probabilistic states rather than fixed quantities. Transactions act as measurements that collapse these states into observed market prices, providing a new perspective on valuation under uncertainty.

Blockchain Network Analysis: A Comparative Study of Decentralized Banks

Liu, Y., et al. (2023)Decentralized Finance ProgramScience and Information ConferenceDOI: 10.48550/arXiv.2212.05632

A comparative study of core-periphery network structure across four decentralized banks — Liquity, Aave, MakerDao, and Compound — finding that MakerDao and Compound exhibit greater decentralization in transactions, while all four protocols show concentration around primary external addresses such as Huobi, Coinbase, and Binance.
