Parity-unfolded distillation architecture for noise-biased platforms

Konstantin Tiurev, Christoph Fleckenstein, Christophe Goeller +6

We introduce the parity-unfolded architecture, a fault-tolerant quantum computing scheme that relies on direct preparation and teleportation of small-angle rotations

YZ-plane measurement-based quantum computation: Universality and Parity Architecture implementation

Jaroslav Kysela, Katharina Ludwig, Nitica Sakharwade +2

We define the class of register-logic graphs and prove that any uniformly deterministic measurement-based quantum computation (MBQC) where the inputs coincide with the outputs must…

The Parity Flow Formalism: Tracking Quantum Information Throughout Computation

Berend Klaver, Katharina Ludwig, Anette Messinger +4

We propose the Parity Flow formalism, a method for tracking the information flow in quantum circuits. This method adds labels to quantum circuit diagrams such that the action of Cl…

SWAP-less Implementation of Quantum Algorithms

Berend Klaver, Stefan Rombouts, Michael Fellner +4

We present a formalism based on tracking the flow of parity quantum information to implement algorithms on devices with limited connectivity without qubit overhead, SWAP operations…

Fault-tolerant multi-qubit gates in Parity Codes

Anette Messinger, Christophe Goeller, Wolfgang Lechner

We present a set of efficiently implementable logical multi-qubit gates in concatenated quantum error correction codes using parity qubits. In particular, we show how fault-toleran…

Fault-tolerant quantum computing with the parity code and noise-biased qubits

Anette Messinger, Valentin Torggler, Berend Klaver +2

We present a fault-tolerant universal quantum computing architecture based on a code concatenation of biased-noise qubits and the parity architecture. The parity architecture can b…
