Maximum-Likelihood Quantum State Tomography by Cover's Method with Non-Asymptotic Analysis
Chien-Ming Lin, Hao-Chung Cheng, Yen-Huan Li
We propose an iterative algorithm that computes the maximum-likelihood estimate in quantum state tomography. The optimization error of the algorithm converges to zero at an $O ( (…
Qubit-efficient encoding scheme for quantum simulations of electronic structure
Yu Shee, Pei-Kai Tsai, Cheng-Lin Hong +2
Simulating electronic structure on a quantum computer requires encoding of fermionic systems onto qubits. Common encoding methods transform a fermionic system of spin-orbitals…
Minimizing Quantum Renyi Divergences via Mirror Descent with Polyak Step Size
Jun-Kai You, Hao-Chung Cheng, Yen-Huan Li
Quantum information quantities play a substantial role in characterizing operational quantities in various quantum information-theoretic problems. We consider numerical computation…
On the Existence of the Augustin Mean
Hao-Chung Cheng, Baris Nakiboglu
The existence of a unique Augustin mean and its invariance under the Augustin operator are established for arbitrary input distributions with finite Augustin information for channe…
Learning quantum circuits of some gates
Ching-Yi Lai, Hao-Chung Cheng
In this paper, we study the problem of learning an unknown quantum circuit of a certain structure. If the unknown target is an -qubit Clifford circuit, we devise an efficient al…
