Quantum Magic in early FTQC: From Diagonal Clifford Hierarchy No-Go Theorems to Architecture Design Blueprints
Hsueh-Hao Lu, Yasunari Suzuki, Yasunobu Nakamura +1
We address the circuit-design problem of maximizing quantum magic in early fault-tolerant quantum computing (early FTQC), where logical dynamics natively take the form of alternati…

Learning magic in the Schwinger model
Samuel Crew, Hsueh Hao Lu
We demonstrate the use of variational neural network quantum states to study non-stabilizerness in qubit-regularised quantum field theory. Applying the methodology recently introdu…

Biorthogonal quench dynamics of entanglement and quantum geometry in PT-symmetric non-Hermitian systems
Hsueh-Hao Lu, Po-Yao Chang
We explore the quench dynamics of PT-symmetric non-Hermitian systems by utilizing the biorthogonal formalism. We analyze quench dynamics of observable quantities, the quantum geome…
