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…
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…
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…
