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…

Pretty good state transfer via adaptive quantum error correction
Akshaya Jayashankar, Prabha Mandayam
We examine the role of quantum error correction (QEC) in achieving pretty good quantum state transfer over a class of -d spin Hamiltonians. Recasting the problem of state transf…
