Optimizing sparse quantum state preparation with measurement and feedforward
Yao-Cheng Lu, Han-Hsuan Lin
Quantum state preparation (QSP) is a key component in many quantum algorithms. In particular, the problem of sparse QSP (SQSP) $\unicode{x2013}$ the task of preparing the states wi…

Getting almost all the bits from a quantum random access code
Han-Hsuan Lin, Ronald de Wolf
A quantum random access code (QRAC) is a map that encodes -bit strings into -qubit quantum states , in a way that allows us to recover any one bit of $…

D-commuting SYK model: building quantum chaos from integrable blocks
Ping Gao, Han Lin, Cheng Peng
We construct a new family of quantum chaotic models by combining multiple copies of integrable commuting SYK models. As each copy of the commuting SYK model does not commute with o…
