The simplest decomposition of a Toffoli gate acting on 3 qubits requires five 2-qubit gates. If
we restrict ourselves to controlled-sign (or controlled-not) gates this number climbs to 6. We …

Minimizing the resources required to build logic gates into useful processing circuits is key to
realizing quantum computers. Although the salient features of a quantum computer have …

By harnessing weak cross‐Kerr nonlinearities, it proposes two deterministic hyperparallel
quantum control gates, including the hyperparallel controlled‐NOT (hyper‐CNOT) gate and …

The quantum Toffoli gate is one of the most important three-qubit gates, but it is challenging
to construct a chip according to the complicated traditional circuit. Using the optimized 3D …

In this paper, with the weak cross-Kerr nonlinearity, we first present a special experimental

Implementation of quantum logic gates with linear optical elements plays a prominent role in
quantum computing due to their relatively easy manipulation and realization. We present …

Quantum gates designed with minimized resources overhead have a crucial role in quantum
information processing. Here, based on the degrees of freedom (DoFs) of photons and Λ …

To date, all work concerning the construction of quantum logic gates, an essential part of
quantum computing, has focused on operating in one degree of freedom (DOF) for quantum …

We present an error-detected hyperparallel Toffoli (hyper-Toffoli) gate for a three-photon
system based on the interface between polarized photon and cavity-nitrogen-vacancy (NV) …

High‐efficiency quantum information processing is equivalent to the fewest quantum
resources and simplest operations by means of logic qubit gates. Based on the reflection …
