Résumé :

A simplified Toffoli gate coincides with the Toffoli gate except that the result is allowed to differ on one computational basis state by a phase factor. We prove that the simplified Toffoli gate implementation by Margolus is optimal, in the sense that it attains a lower bound of {\em three} controlled-not gates, and subject to that, a sharp lower bound of {\em four} single-qubit gates. We also discuss optimal implementations of other simplified Toffoli gates, and explain why the phase factor $-1$ invariably occurs in such implementations.

Résumé :

We present a scheme for implementing a Toffoli gate. The superconducting quantum interference devices are coupled to a resonant cavity with nonidentical SQUID–cavity coupling constants. So only one interaction between SQUID and cavity is required, and a Toffoli gate can be obtained. The method can be generalized to the N-qubit case easily and the scheme is insensitive to systematic coupling error.

Résumé :

This paper analyzes and proves that the relationship between the output results of the homotypic Toffoli gate which is series cascade and the number of the gates which are series cascade. In order to guarantee the convergence of the process of the series cascade, we gave the counting results of the series cascade network for Toffoli gates, and proved that in the input vector (0, 1, …, 2n-1), the number of the bit vectors with Hamming weight H(w)≥n-1 is equal to the bit number of bit vectors plus 1, and obtained the conclusion that there are (n+1)! kinds of transformation for Toffoli gate series cascade network. Simultaneously we provide the series cascade network algorithm of the Toffoli gates. The reversible network cascade system designed by the above algorithm verified the validity of this algorithm.

Résumé :

There are various gate sets used for describing quantum computation. A particularly popular one consists of Clifford gates and arbitrary single-qubit phase gates. Computations in this gate set can be elegantly described by the ZX-calculus, a graphical language for a class of string diagrams describing linear maps between qubits. The ZX-calculus has proven useful in a variety of areas of quantum information, but is less suitable for reasoning about operations outside its natural gate set such as multi-linear Boolean operations like the Toffoli gate. In this paper we study the ZH-calculus, an alternative graphical language of string diagrams that does allow straightforward encoding of Toffoli gates and other more complicated Boolean logic circuits. We find a set of simple rewrite rules for this calculus and show it is complete with respect to matrices over Z[12], which correspond to the approximately universal Toffoli+Hadamard gateset. Furthermore, we construct an extended version of the ZH-calculus that is complete with respect to matrices over any ring R where 1+1 is not a zero-divisor.

Résumé :

Set Intersection Cardinality (SI-CA) computes the intersection cardinality of two parties’ sets, which has many important and practical applications such as data mining and data analysis. However, in the face of big data sets, it is difficult for two parties to execute the SI-CA protocol repeatedly. In order to reduce the execution pressure, a Private Set Intersection Cardinality (PSI-CA) protocol based on a quantum homomorphic encryption scheme for the Toffoli gate is proposed. Two parties encode their private sets into two quantum sequences and encrypt their sequences by way of a quantum homomorphic encryption scheme. After receiving the encrypted results, the semi-honest third party (TP) can determine the equality of two quantum sequences with the Toffoli gate and decrypted keys. The simulation of the quantum homomorphic encryption scheme for the Toffoli gate on two quantum bits is given by the IBM Quantum Experience platform. The simulation results show that the scheme can also realize the corresponding function on two quantum sequences.

Résumé :

L'application des résonances de Förster à plusieurs corps est étudiée pour réaliser des circuits de portes quantiques multi-qbits. Deux nouveaux types de transitions borroméennes à trois atomes utilisant un atome relais ont été proposées et étudiées numériquement. En particulier, une résonance de Förster à trois atomes non isolée et contrôlée par effet Stark entre des états S et P de niveaux élevés n = 80, 81, 82 avec des atomes de Rb isolés dans des pièges optiques a été modélisée. Une résonance de Förster isolée à trois atomes a également été démontrée pour les états n = 70, 71 des atomes Rb. Les résonances ont été étudiées dans une configuration spatiale fixe, ce qui nous a permis de démontrer l'évolution cohérente de la population et de la phase des états collectifs impliqués. Des schémas de portes de Toffoli à trois qubits ont été développés et modélisés numériquement sur la base des résonances démontrées dans des ensembles à trois atomes. En outre, un schéma généralisé de porte de phase doublement contrôlée CCPHASE a été développé sur la base de la résonance de Förster à trois corps induite par radiofréquence. De plus, un schéma de porte quantique similaire a été proposé sur la base de la résonance de Förster induite par radiofréquence à deux atomes avec un déplacement contrôlé par interaction avec le troisième. Les performances rapides et la grande fidélité des schémas proposés, ainsi que leur robustesse potentielle aux erreurs, nous permettent d'espérer le succès d'une réalisation expérimentale prochainement
Application of few-body Förster resonances for implementation of multiqubit quantum gate circuits has been investigated. New types of three-atom Borromean transitions based on the relay atom have been proposed and numerically studied. In particular, a Stark-controlled non-isolated three-atom Förster resonance between high-lying n = 80, 81, 82 S − P states of Rb atoms isolated in individual optical traps has been modeled. Isolated three-atom Förster resonance has also been demonstrated for n = 70, 71 states of Rb atoms. The resonances were investigated in a fixed spatial configuration, allowing us to demonstrate the coherent population and phase dynamics of the collective states involved. Three-qubit Toffoli gates schemes have been developed and numerically modeled based on the demonstrated resonances. Also, a generalized doubly controlled phase CCPHASE gate scheme has been developed based on the radiofrequency-induced three-body Förster resonance. Additionally, a similar quantum gate scheme has been proposed based on two-atom RF-induced Förster resonance with controlled displacement. The fast performance and high fidelity of the proposed schemes, as well as their potential robustness to errors, allow us to expect a successful experimental implementation in the near future

Résumé :

Most promising implementations in quantum computing are based on Linear Nearest Neighbor (LNN) architectures, where qubits only interact with neighbors. Multi-control Toffoli gates are used in many quantum applications such as error correction and algorithms like Shor's factorization. Typically, to implement a multi-control Toffoli gate in an LNN architecture, additional operations called swap gates are required to bring the qubits adjacent to each other. This may increase the total number of quantum gates and computational overhead of the circuit. Here, we propose a new method to implement multi-control Toffoli gates in LNN arrays without using swap gates. The circuit reduction techniques discussed here are based on 3 lemmas. Using the lemmas, we show how to implement multi-control Toffoli gates in LNN arrays with different separations between the control and target qubits. The key feature of our scheme is to involve qubits other than control and target qubits to take part in gate operations. We call these qubits auxiliary" qubits and they are used in our gate decomposition protocols. Auxiliary qubits can be in any arbitrary states, a|0>+beta|1> , and are always restored back to their original states. Since we do not use swap gates to bring qubits adjacent to each other, compared to circuits using swap gates, the total number of gate operations used in our method is decreased, and the quantum cost is lowered. In addition, for implementing multi-control Toffoli gate operations efficiently in LNN arrays, we also show how to extend our protocols to 2D arrays. Here, in addition to translating our gate reduction techniques, directly from 1D to 2D, we use further simplification techniques for particular arrangements of qubits.

Résumé :

AbstractVerifying equivalence between two quantum circuits is a hard problem, that is nonetheless crucial in compiling and optimizing quantum algorithms for real-world devices. This paper gives a Turing reduction of the (universal) quantum circuits equivalence problem to weighted model counting (WMC). Our starting point is a folklore theorem showing that equivalence checking of quantum circuits can be done in the so-called Pauli-basis. We combine this insight with a WMC encoding of quantum circuit simulation, which we extend with support for the Toffoli gate. Finally, we prove that the weights computed by the model counter indeed realize the reduction. With an open-source implementation, we demonstrate that this novel approach can outperform a state-of-the-art equivalence-checking tool based on ZX calculus and decision diagrams.
