Optimal two-mode bosonic loss codes from finite group symmetry
Argyris Giannisis Manes, Mahadevan Subramanian, Liang Jiang
Photon loss is a dominant noise process in bosonic quantum hardware, including superconducting cavities. Fixed-total-photon-number qubit encodings in two bosonic modes retain the l…
Quantum channel learning with limited parallel access
Mahadevan Subramanian, Hyukgun Kwon, Liang Jiang
Quantum channels can be characterized by their action on an orthogonal operator basis, where these operators are related to observable properties of the quantum system. For qudit a…
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…
Efficient two-qutrit gates in superconducting circuits using parametric coupling
Mahadevan Subramanian, Adrian Lupascu
Recently, significant progress has been made in the demonstration of single qutrit and coupled qutrit gates with superconducting circuits. Coupled qutrit gates have significantly l…
Shallow-Depth Variational Quantum Hypothesis Testing
Mahadevan Subramanian, Sai Vinjanampathy
We present a variational quantum algorithm for differentiating several hypotheses encoded as quantum channels. Both state preparation and measurement are simultaneously optimized u…
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…
