Quantum channel learning with limited parallel access
Mahadevan Subramanian, Hyukgun Kwon, Liang Jiang
Quantum channels can characterized by their action on an orthogonal operator basis, where these operators are related to observable properties of the quantum system. For qudit and…

Achievable rates for concatenated square Gottesman-Kitaev-Preskill codes
Mahadevan Subramanian, Guo Zheng, Liang Jiang
The Gottesman-Kitaev-Preskill (GKP) codes are known to achieve optimal rates under displacement noise and pure loss channels, which establishes theoretical foundations for its opti…

Resonant weak-value enhancement for solid-state quantum metrology
Mahadevan Subramanian, Amal Mathew, Bhaskaran Muralidharan
Quantum metrology that employs weak-values can potentially effectuate parameter estimation with an ultra-high sensitivity and has been typically explored across quantum optics setu…
