Global Precision Bounds and Success-Probability Guarantees in Quantum Parameter Learning
Federico Belliardo, James W. Gardner, Liang Jiang +1
Quantum metrology offers the possibility of quantum enhancements of the precision of various sensing tasks. In this manuscript, we tackle two open problems in the theory of single-…
Integer Linear Programming Decoder for Abelian and Non-Abelian Topological Codes
Dian Jing, Aubrey Zhang, Liang Jiang +1
Topological orders (TOs) are widely used as quantum error-correcting codes, with anyon excitations serving as error syndromes. For certain Abelian TOs, decoding can be performed by…
Quantum superresolution and noise spectroscopy with quantum computing
James W. Gardner, Federico Belliardo, Gideon Lee +2
Quantum metrology of an incoherent signal is a canonical sensing problem related to superresolution and noise spectroscopy. We show that quantum computing can accelerate searches f…
Quantum Advantage in Learning Mixed Unitary Channels
Yue Tu, Liang Jiang
We study the task of learning mixed unitary channels using Fisher information, under different quantum resource assumptions including ancilla and concatenation. Our result shows th…
Intrinsic Heralding and Optimal Decoders for Non-Abelian Topological Order
Dian Jing, Pablo Sala, Liang Jiang +1
Topological order (TO) provides a natural platform for storing and manipulating quantum information. However, its stability to noise has only been systematically understood for Abe…
Local unitary decomposition of tripartite arbitrary leveled qudit stabilizer states into -level-qudit EPR and GHZ state
Yat Wong, Liang Jiang
We study the entanglement structure of tripartite stabilizer states on qudits of dimension , distributed across parties , , and , under arbitrary local unitaries. P…
Timescales, Squeezing and Heisenberg Scalings in Many-Body Continuous Sensing
Gideon Lee, Ron Belyansky, Liang Jiang +1
The continuous monitoring of driven-dissipative systems offers new avenues for quantum advantage in metrology. This approach mixes temporal and spatial correlations in a manner dis…
Implementation of a quantum addressable router using superconducting qubits
Connie Miao, Sébastien Léger, Ziqian Li +3
The implementation of a quantum router capable of performing both quantum signal routing and quantum addressing (a Q2-router) represents a key step toward building quantum networks…
Analysis and Suppression of Errors in Quantum Random Access Memory under Extended Noise Models
Rohan Mehta, Gideon Lee, Liang Jiang
Quantum random access memory (QRAM) is required for numerous quantum algorithms and network architectures. Previous work has shown that the ubiquitous bucket-brigade QRAM is highly…
Performance and achievable rates of the Gottesman-Kitaev-Preskill code for pure-loss and amplification channels
Guo Zheng, Wenhao He, Gideon Lee +2
Quantum error correction codes protect information from realistic noisy channels and lie at the heart of quantum computation and communication tasks. Understanding the optimal perf…
Coordinating Decisions via Quantum Telepathy
Dawei Ding, Liang Jiang
Quantum telepathy is the phenomenon where two non-communicating parties can exhibit correlated behaviors that are impossible to achieve using classical resources. This is also know…
