High-Distance Error-Correcting Codes for Fermion-to-Qubit Mappings in 2D and 3D
Ruby Wei, Aqua Chung, Luke Coffman +2
Quantum simulation of fermionic systems is a leading application of quantum computers. One promising approach is to represent fermions with qubits via fermion-to-qubit mappings. In…
Entanglement Renormalization Circuits for Chiral Topological Order
Su-Kuan Chu, Guanyu Zhu, Alexey V. Gorshkov
Entanglement renormalization circuits are quantum circuits that can be used to prepare large-scale entangled states. For years, it has remained a mystery whether there exist scale-…
Implementing a Fast Unbounded Quantum Fanout Gate Using Power-Law Interactions
Andrew Y. Guo, Abhinav Deshpande, Su-Kuan Chu +6
The standard circuit model for quantum computation presumes the ability to directly perform gates between arbitrary pairs of qubits, which is unlikely to be practical for large-sca…
Destructive Error Interference in Product-Formula Lattice Simulation
Minh C. Tran, Su-Kuan Chu, Yuan Su +2
Quantum computers can efficiently simulate the dynamics of quantum systems. In this paper, we study the cost of digitally simulating the dynamics of several physically relevant sys…
Photon pair condensation by engineered dissipation
Ze-Pei Cian, Guanyu Zhu, Su-Kuan Chu +4
Dissipation can usually induce detrimental decoherence in a quantum system. However, engineered dissipation can be used to prepare and stabilize coherent quantum many-body states.…
Scale-Invariant Continuous Entanglement Renormalization of a Chern Insulator
Su-Kuan Chu, Guanyu Zhu, James R. Garrison +5
The multi-scale entanglement renormalization ansatz (MERA) postulates the existence of quantum circuits that renormalize entanglement in real space at different length scales. Cher…
Two-Dimensional Dilaton Gravity Theory and Lattice Schwarzian Theory
Su-Kuan Chu, Chen-Te Ma, Chih-Hung Wu
We report a holographic study of a two-dimensional dilaton gravity theory with the Dirichlet boundary condition for the cases of non-vanishing and vanishing cosmological constants.…
Maximally Entangled State and Bell's Inequality in Qubits
Su-Kuan Chu, Chen-Te Ma, Rong-Xin Miao +1
A maximally entangled state is a quantum state which has maximum von Neumann entropy for each bipartition. Through proposing a new method to classify quantum states by using concur…
Bell's Inequality, Generalized Concurrence and Entanglement in Qubits
Po-Yao Chang, Su-Kuan Chu, Chen-Te Ma
It is well known that the maximal violation of the Bell's inequality for a two-qubit system is related to the entanglement formation in terms of a concurrence. However, a generaliz…
Bell's Inequality and Entanglement in Qubits
Po-Yao Chang, Su-Kuan Chu, Chen-Te Ma
We propose an alternative evaluation of quantum entanglement by measuring the maximum violation of the Bell's inequality without performing a partial trace operation. This proposal…
