The role of permutation gates for universal quantum computing is investigated. The “magic” of computation is clarified in the permutation gates, their eigenstates, the Wootters discrete Wigner function, and state-dependent contextuality (following many contributions on this subject). A first classification of a few types of resulting magic states in low dimensions is performed.

Representation Matching For Remote Quantum Computing

It is shown that the representation matching protocol is capable of reducing the communication or memory cost to almost minimum in various tasks, including delegated execution of unitary gate arrays, permutation gates, and unitary conjugation, as well as the storage and retrieval ofunitary gates.

Magic informationally complete POVMs with permutations

It is shown that a subset of such magic states, when acting on the generalized Pauli group, define (asymmetric) informationally complete POVMs, investigated in dimensions 2–12, and exhibit simple finite geometries in their projector products.

Contextuality as a resource for qubit quantum computation

We describe a scheme of quantum computation with magic states on qubits for which contextuality is a necessary resource possessed by the magic states. More generally, we establish contextuality as a

Universal quantum computation with ideal Clifford gates and noisy ancillas (14 pages)

We consider a model of quantum computation in which the set of elementary operations is limited to Clifford unitaries, the creation of the state |0>, and qubit measurement in the computational basis.

The resource theory of stabilizer quantum computation

A resource theory, analogous to the theory of entanglement, is developed that is relevant for fault-tolerant stabilizer computation and introduces two quantitative measures for the amount of non-stabilizer resource, including the sum of the negative entries of the discrete Wigner representation of a quantum state.

Contextuality supplies the ‘magic’ for quantum computation

This work proves a remarkable equivalence between the onset of contextuality and the possibility of universal quantum computation via ‘magic state’ distillation, which is the leading model for experimentally realizing a fault-tolerant quantum computer.
