Comparing two-qubit and multiqubit gates within the toric code

چکیده

In some quantum computing architectures, entanglement of an arbitrary number qubits can be generated in a single operation. This property has many potential applications, and may specifically useful for error correction (QEC). Stabilizer measurements then implemented using multiqubit gate instead several two-qubit gates, thus reducing circuit depth. this study, the toric code is used as benchmark to compare performance five-qubit gates within parity-check circuits. We consider trapped ion that are controlled via Raman transitions, where primary source assumed spontaneous photon scattering. show M\o{}lmer-S\o{}rensen offers approximately $40%$ improvement over terms fault tolerance threshold. result indicates advantage context QEC.

Randomized benchmarking of multiqubit gates.

We describe an extension of single-qubit gate randomized benchmarking that measures the error of multiqubit gates in a quantum information processor. This platform-independent protocol evaluates the performance of Clifford unitaries, which form a basis of fault-tolerant quantum computing. We implemented the benchmarking protocol with trapped ions and found an error per random two-qubit Clifford...

Hybrid topological-spin qubit systems for two-qubit-spin gates

We investigate a hybrid quantum system involving spin qubits, based on the spins of electrons confined in quantum dots, and topological qubits, based on Majorana fermions. In such a system, gated control of the charge on the quantum dots allows transfer of quantum information between the spin and topological qubits, and the topological system can be used to facilitate transfer of spin qubits be...

Two-qubit gates for resonant exchange qubits.

A new approach to single-qubit operations using exchange interactions of single electrons in gate-defined quantum dots has recently been demonstrated: the resonant exchange qubit. We show that two-qubit operations, specifically the controlled phase gate, can be performed between resonant exchange qubits very straightforwardly, using a single exchange pulse. This is in marked contrast to the bes...

Improving the purity of one- and two-qubit gates

The experimental realization of one-qubit gates in solid state setups [1–3] and two-qubit gates in ion traps [4, 5] and Josephson junctions [6] has demonstrated that these systems provide remarkable coherence properties although the goal of 10−5 errors per gate operation [7] has not yet been accomplished experimentally. The unavoidable coupling to external degrees of freedomand the thereby caus...

Coherent error suppression in multiqubit entangling gates.

We demonstrate a simple pulse shaping technique designed to improve the fidelity of spin-dependent force operations commonly used to implement entangling gates in trapped ion systems. This extension of the Mølmer-Sørensen gate can theoretically suppress the effects of certain frequency and timing errors to any desired order and is demonstrated through Walsh modulation of a two qubit entangling ...
