Enhanced quantum capacity thresholds from symmetry
Avantika Agarwal, Amolak Ratan Kalra, Sungjai Lee +4
The quantum capacity captures the value of a quantum channel for transmitting quantum information, establishing the fundamental limits on quantum communication. In spite of its cen…
On Error Thresholds for Pauli Channels: Some answers with many more questions
Avantika Agarwal, Alan Bu, Amolak Ratan Kalra +3
This paper focuses on error thresholds for Pauli channels. We numerically compute lower bounds for the thresholds using the analytic framework of coset weight enumerators pioneered…
Buildings for Synthesis with Clifford+R
Mark Deaconu, Nihar Gargava, Amolak Ratan Kalra +2
We study the problem of exact synthesis for the Clifford+R gate set and give the explicit structure of the underlying Bruhat-Tits building for this group. In this process, we also…
Stabilizer Ranks, Barnes Wall Lattices and Magic Monotones
Amolak Ratan Kalra, Pulkit Sinha
In 2024, Kliuchnikov and Schönnenbeck showed a connection between the Barnes Wall lattices, stabilizer states and Clifford operations. In this work, we study their results and rela…
Invariant Theory, Magic State Distillation, and Bounds on Classical Codes
Amolak Ratan Kalra, Shiroman Prakash
We show that the physical consistency of magic state distillation imposes new constraints on the weight enumerators of classical error-correcting codes. We establish that for $|T\r…
Multi-qutrit exact synthesis
Amolak Ratan Kalra, Manimugdha Saikia, Dinesh Valluri +2
We present an exact synthesis algorithm for qutrit unitaries in over the Clifford gate set with at most one ancilla. This extends…
