Quantum codes in the Lee metric
Jinkang Guo, Yiqiu Han, Aranya Chakraborty +4
We introduce a quantum coding framework for discrete small-shift noise, in which errors on qudits are modeled as low-weight - and -type Pauli shifts, analogous to small phase…

Achieving the limits of automorphism gates
Jin Ming Koh, Shayan Majidy, Aranya Chakraborty +3
Universal fault-tolerant quantum computing combines versatile but expensive operations with specialized but cheap ones. Its efficiency depends on how much computation can be pushed…

No-Go Theorem on Fault Tolerant Gadgets for Multiple Logical Qubits
Aranya Chakraborty, Daniel Gottesman
Identifying stabilizer codes that admit fault-tolerant implementations of the full logical Clifford group would significantly advance fault-tolerant quantum computation. Motivated…
