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…
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…
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…
