Factory-based Fault-tolerant Preparation of Quantum Polar Codes Encoding One logical Qubit
Ashutosh Goswami, Mehdi Mhalla, Valentin Savin
A fault-tolerant way to prepare logical code-states of Q1 codes, i.e., quantum polar codes encoding one qubit, has been recently proposed. The fault tolerance therein is guaranteed…
Fault-Tolerant Preparation of Quantum Polar Codes Encoding One Logical Qubit
Ashutosh Goswami, Mehdi Mhalla, Valentin Savin
This paper explores a new approach to fault-tolerant quantum computing (FTQC), relying on quantum polar codes. We consider quantum polar codes of Calderbank-Shor-Steane type, encod…
Quantum Polarization of Qudit Channels
Ashutosh Goswami, Mehdi Mhalla, Valentin Savin
We provide a generalization of quantum polar codes to quantum channels with qudit-input, achieving the symmetric coherent information of the channel. Our scheme relies on a channel…
Multilevel Polarization for Quantum Channels
Ashutosh Goswami, Mehdi Mhalla, Valentin Savin
Recently, a purely quantum version of polar codes has been proposed in [1] based on a quantum channel combining and splitting procedure, where a randomly chosen two-qubit Clifford…
Polarization of Quantum Channels using Clifford-based Channel Combining
Frédéric Dupuis, Ashutosh Goswami, Mehdi Mhalla +1
We provide a purely quantum version of polar codes, achieving the symmetric coherent information of any qubit-input quantum channel. Our scheme relies on a recursive channel combin…
Quantum Coherence and Holevo Bound
Ashutosh K. Goswami, Prasanta K. Panigrahi
We establish the equivalence between the loss of coherence due to mixing in a quantum system and the loss of information after performing a projective measurement. Subsequently, it…
