Quantum Fisher Information as the Speed Limit for Multipartite Entanglement
Zain H. Saleem, Da-Wei Luo, Anjala M. Babu +3
We derive a universal upper bound on the speed of multipartite entanglement generation. For arbitrary differentiable pure multipartite states undergoing parameter-dependent evoluti…
Quantum Fisher Information and the Curvature of Entanglement
Zain H. Saleem, Anil Shaji, Anjala M Babu +4
We explore the relationship between quantum Fisher information (QFI) and the negative of the second derivative of concurrence with respect to the coupling between two qubits, refer…
Fault Tolerant Quantum Error Mitigation
Alvin Gonzales, Anjala M Babu, Ji Liu +2
Typically, fault-tolerant operations and code concatenation are reserved for quantum error correction due to their resource overhead. Here, we show that fault tolerant operations h…
Finding good quantum codes using the Cartan form
Akshaya Jayashankar, Anjala M Babu, Hui Khoon Ng +1
We present a simple and fast numerical procedure to search for good quantum codes for storing logical qubits in the presence of independent per-qubit noise. In a key departure from…
