Characterizing Coherent Errors using Matrix-Element Amplification
Jonathan A. Gross, Elie Genois, Dripto M. Debroy +4
Repeating a gate sequence multiple times amplifies systematic errors coherently, making it a useful tool for characterizing quantum gates. However, the precision of such an approac…
Ever more optimized simulations of fermionic systems on a quantum computer
Qingfeng Wang, Ze-Pei Cian, Ming Li +2
Despite using a novel model of computation, quantum computers break down programs into elementary gates. Among such gates, entangling gates are the most expensive. In the context o…
Extracting Wilson loop operators and fractional statistics from a single bulk ground state
Ze-Pei Cian, Mohammad Hafezi, Maissam Barkeshli
An essential aspect of topological phases of matter is the existence of Wilson loop operators that keep the ground state subspace invariant. Here we present and implement an \it un…
Shadow Distillation: Quantum Error Mitigation with Classical Shadows for Near-Term Quantum Processors
Alireza Seif, Ze-Pei Cian, Sisi Zhou +2
Mitigating errors in quantum information processing devices is especially important in the absence of fault tolerance. An effective method in suppressing state-preparation errors i…
Cross-Platform Comparison of Arbitrary Quantum Computations
Daiwei Zhu, Ze-Pei Cian, Crystal Noel +14
As we approach the era of quantum advantage, when quantum computers (QCs) can outperform any classical computer on particular tasks, there remains the difficult challenge of how to…
Light-matter interactions in synthetic magnetic fields: Landau-photon polaritons
Daniele De Bernardis, Ze-Pei Cian, Iacopo Carusotto +2
We study light-matter interactions in two dimensional photonic systems in the presence of a spatially homogeneous synthetic magnetic field for light. Specifically, we consider one…
Entanglement entropy scaling transition under competing monitoring protocols
Mathias Van Regemortel, Ze-Pei Cian, Alireza Seif +2
Dissipation generally leads to the decoherence of a quantum state. In contrast, numerous recent proposals have illustrated that dissipation can also be tailored to stabilize many-b…
Extraction of many-body Chern number from a single wave function
Hossein Dehghani, Ze-Pei Cian, Mohammad Hafezi +1
The quantized Hall conductivity of integer and fractional quantum Hall (IQH and FQH) states is directly related to a topological invariant, the many-body Chern number. The conventi…
Engineering Quantum Hall Phases in Synthetic Bilayer Graphene System
Ze-Pei Cian, Tobias Grass, Abolhassan Vaezi +2
Synthetic quantum Hall bilayer (SQHB), realized by optically driven monolayer graphene in the quantum Hall regime, provides a flexible platform for engineering quantum Hall phases…
Many-body Chern number from statistical correlations of randomized measurements
Ze-Pei Cian, Hossein Dehghani, Andreas Elben +5
One of the main topological invariants that characterizes several topologically-ordered phases is the many-body Chern number (MBCN). Paradigmatic examples include several fractiona…
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.…
